THE ITEMS IN THE FOLLOWING SUMMARY ARE DESCRIBED IN MORE DETAIL LATER IN THIS
PROSPECTUS. THIS SUMMARY PROVIDES AN OVERVIEW OF SELECTED INFORMATION AND DOES
NOT CONTAIN ALL THE INFORMATION YOU SHOULD CONSIDER. THEREFORE, YOU SHOULD ALSO
READ THE MORE DETAILED INFORMATION SET OUT IN THIS PROSPECTUS, THE FINANCIAL

INTERNET.COM
 
internet.com owns and operates a leading network of integrated
business-to-business Web sites and related Internet media properties focused
solely on the Internet industry. Our network of Internet media properties
consists of 61 Web sites, 43 e-mail newsletters, 55 online discussion forums and
52 moderated e-mail discussion lists. Our network is organized into nine
vertical content channels to serve our Internet users, which include Internet
industry and Internet technology professionals, Web developers and experienced
Internet users. We provide our audience, or community of Internet users, with
the following resources:
 
- -  real-time Internet industry news
 
- -  tutorials, training and skills development
 
- -  Internet market research
 
- -  buyer's guides and products reviews
 
- -  archives of definitive industry publications
 
- -  discussion forums
 
- -  software downloads
 
- -  expert advice
 
The Internet has emerged as a global distribution network for real-time news and
information, an environment for online communities and a marketplace in which
commerce is conducted. International Data Corporation, or IDC, estimates that
the number of Uniform Resource Locators, or URLs, will grow from approximately
925 million in 1998 to 13.1 billion in 2003. This growth has created a rapidly
expanding group of Internet professionals with a critical need for timely
content, community and commerce resources to assist them in their daily work and
purchasing decisions. Our network provides a comprehensive source of the latest
Internet news and information for our community of Internet users. It also
provides the ability to share information and evaluate, compare and purchase
Internet-related products and services.
 
We also provide advertisers and vendors with focused channels to reach our
community of Internet industry and Internet technology professionals, many of
whom either make or influence Internet technology purchasing decisions. We have
had over 450 advertisers on our network, including Biztravel.com, Dell Computer
Corporation, International Business Machines Corporation, Lucent Technologies
Inc., Macromedia Inc., Microsoft Corporation, Nortel Networks Corporation,
Oracle Corporation, OrderTrust LLC and Surfree.com Inc.
 
We have rapidly built a large and focused network of Internet media properties,
through internal development and acquisitions. We have experience identifying,
evaluating, acquiring and integrating Internet media properties which are
complementary to our content, community and commerce offerings. Since July 1995,
we have made 28 acquisitions of Internet media properties, consisting of 37 Web
sites, 29 e-mail newsletters, 16 online discussion forums and four

moderated e-mail discussion lists. We have made 17 of these 28 acquisitions
since March 1998. Our size and recent growth are illustrated by the following
statistics for the months of April 1998 and April 1999:

Our objective is to maintain and strengthen our position as a leading provider
of integrated business-to-business vertical content focused solely on the
Internet industry. We intend to achieve this objective by continuing to execute
the following strategies:
 
      -      increase our proprietary content offerings and services;
 
      -      grow through targeted acquisitions;
 
      -      increase traffic and enhance worldwide brand recognition;
 
      -      expand revenue opportunities; and
 
      -      increase our international presence.
 
Prior to the acquisition of Mecklermedia Corporation by Penton Media, Inc. in
November 1998, we operated since December 1994 as one of three divisions which
comprised Mecklermedia. Our predecessor Web sites, MECKLERWEB.COM and
IWORLD.COM, were also dedicated to covering the Internet industry. In connection
with this acquisition, Penton Media determined that Mecklermedia's Internet
business was not consistent with its planned strategic direction. To address
this issue, Alan M. Meckler, Mecklermedia's Chairman and Chief Executive
Officer, purchased an 80.1% interest in internet.com LLC, a business formed by
Penton Media to hold the Internet business acquired from Mecklermedia. See
"Certain Transactions--Formation Transactions."
 
internet.com Corporation was incorporated on April 5, 1999 in the State of
Delaware. internet.com LLC will be merged with and into internet.com Corporation
immediately preceding the consummation of the offering. Our principal executive
offices are located at 20 Ketchum Street, Westport, Connecticut 06880 and our
telephone number is (203) 226-6967.
 
The information on our Web sites, e-mail newsletters, online discussion forums
and moderated e-mail discussion lists is not a part of this prospectus.
"internet.com" and the internet.com logo are two of our trademarks and service
marks. We have numerous other trademarks and service marks as well. See
"Business--Intellectual Property." This prospectus also references trademarks

                                  RISK FACTORS
 
YOU SHOULD CAREFULLY CONSIDER THE RISKS DESCRIBED BELOW BEFORE MAKING AN
INVESTMENT DECISION. THE RISKS AND UNCERTAINTIES DESCRIBED BELOW ARE NOT THE
ONLY ONES FACING OUR COMPANY. OUR BUSINESS, FINANCIAL CONDITION OR RESULTS OF
OPERATIONS COULD BE HARMED BY ANY OF THE FOLLOWING RISKS. THE TRADING PRICE OF
OUR COMMON STOCK COULD DECLINE DUE TO ANY OF THE FOLLOWING RISKS, AND YOU MIGHT
LOSE ALL OR PART OF YOUR INVESTMENT.
 
RISKS RELATED TO OUR BUSINESS
 
WE HAVE A LIMITED OPERATING HISTORY. Although our predecessor business, iWorld,
began operating in December 1994, internet.com was only formed in November 1998.
Thus, we have a limited operating history upon which you can evaluate our
business. We are subject to the risks, expenses and uncertainties frequently
encountered by companies in the new and rapidly evolving markets for Internet
products and services. For example:
 
      -      we might fail to continue to develop and extend our Internet-based
             content offerings and services;
 
      -      our services may be rejected by Internet users, vendors or
             advertisers;
 
      -      we might be unable to maintain and increase the levels of traffic
             on our network;
 
      -      our competitors may develop or may already have developed similar
             or superior services or products;
 
      -      the market might fail to continue to accept the Internet as an
             advertising medium;
 
      -      we might not be able to successfully sell Internet advertising;
 
      -      market prices for Internet advertising may drop as a result of
             competition or other factors;
 
      -      we might not effectively integrate the technology and operations of
             any acquired businesses or technologies with our operations;
 
      -      the technologies we use in our operations might fail or operate
             poorly; and
 
      -      we might be unable to identify, attract, retain and motivate
             qualified personnel.
 
We might not be successful in addressing these risks or other risks we may face.
If we are unable to adequately address these risks, our business, results of
operations and financial condition would suffer.
 
WE ANTICIPATE CONTINUED LOSSES. We had net losses of approximately $1.2 million
for the year ended September 30, 1996, $2.1 million for the year ended September
30, 1997, $2.7 million for the year ended September 30, 1998 and $3.2 million
for the three months ended March 31, 1999. As of March 31, 1999, we had an
accumulated deficit of approximately $6.1 million and, as a result of the
formation of internet.com in November 1998, we had intangible assets, net, of
$18.6 million. We cannot assure you that our revenues will continue at their
current level or increase in the future. We have not achieved profitability on a
quarterly or annual basis to date and we anticipate that we will continue to
incur net losses for the foreseeable future. Our failure to achieve
profitability could deplete our current capital resources and reduce our ability
to raise additional capital. We expect to increase our operating expenses
significantly, expand our sales and marketing operations and continue to develop
and expand our content offerings and services. If these expenses are not
accompanied by increased revenues, we
 
                                       8
<PAGE>
may not be able to recover the recorded amounts of our intangible assets and our
business, results of operations and financial condition would suffer.
 
OUR QUARTERLY OPERATING RESULTS ARE SUBJECT TO SIGNIFICANT FLUCTUATIONS. Our
quarterly operating results may fluctuate significantly in the future because of
a variety of factors, many of which are outside our control. These factors
include:
 
      -      the level of Internet usage;
 
      -      traffic levels on our network;
 
      -      the demand for advertising on our network, as well as on the
             Internet in general;
 
      -      changes in rates paid for Internet advertising resulting from
             competition or other factors;
 
      -      our ability to enter into or renew key agreements with our
             advertisers and vendors;
 
      -      the amount and timing of costs related to marketing efforts or
             other initiatives;
 
      -      costs incurred as we expand operations;
 
      -      our ability to successfully introduce new content offerings and
             services;
 
      -      new services introduced by us or our competitors;
 
      -      technical difficulties or system downtime affecting the Internet
             generally or the operation of our network; and
 
      -      economic conditions specific to the Internet as well as general
             economic conditions.
 
Therefore, operating results for any particular quarter might not be indicative
of future operating results. We expect to depend primarily on advertising
revenues for the foreseeable future. As a result, the level of advertising
revenues in each quarter is likely to significantly affect our quarterly
revenues and operating results. Our advertising, promotion and selling and
general and administrative expenses are based on expectations of future revenues
and are relatively fixed in the short term. These expenses totaled approximately
$1.7 million during the three months ended March 31, 1999. If our advertising
and other revenues are lower than expected, we might not be able to quickly
reduce spending. In addition, we intend to significantly increase operating
expenses to expand our business. Any shortfall in revenues would have a direct
impact on operating results for a particular quarter and these fluctuations
could affect the market price of our common stock.
 
THERE ARE RISKS ASSOCIATED WITH OUR BUSINESS, WHICH IS DEPENDENT ON INTERNET
ADVERTISING. We have derived approximately 99% of our revenues from
impression-based advertising for each of the three years ended September 30,
1996, 1997 and 1998. No standards have been widely accepted to measure the
effectiveness of Internet advertising. If such standards do not develop,
existing advertisers might not continue their current levels of Internet
advertising. Furthermore, advertisers that have traditionally relied upon other
advertising media may be reluctant to advertise on the Internet. In addition,
advertisers that have already invested substantial resources in other
advertising methods may be reluctant to adopt a new strategy. Our business would
suffer if the market for Internet advertising fails to continue to develop or
develops more slowly than expected. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Business--Our Business
Strategy" and "--Marketing and Sales."
 
                                       9
<PAGE>
It is difficult to predict which, if any, of the pricing models currently used
to sell advertising on the Internet will emerge as the industry standard, which
makes it difficult to project future advertising rates and revenues. For
example, insistence by advertisers that advertising rates be based on the number
of click throughs, or user requests for additional information made by clicking
on the advertisement, instead of rates based solely on the number of advertising
impressions, or the number of times an advertisement is displayed, could
adversely affect revenues. Advertising revenues would suffer if we cannot adapt
to new Internet advertising pricing models. Moreover, filtering software
programs that limit or prevent advertising from being delivered to an Internet
user's computer are available. Widespread adoption of this filtering software by
Internet users could adversely affect the commercial viability of Internet
advertising, which would harm our business.
 
It is important to advertisers that we accurately measure the size and
demographics of our user base and accurately verify the number of advertising
impressions we deliver. We depend on third parties to provide these measurement
services. If they cannot provide these services in the future, we will be
required to perform them ourselves or obtain them from another provider. This
could cause us to incur additional costs or cause interruptions in business
during the time we are replacing these services.
 
WE DEPEND ON A LIMITED NUMBER OF ADVERTISERS. Our largest advertiser,
International Business Machines Corporation, accounted for 17% of our total
revenues for the six months ended March 31, 1999. Our top 20 advertisers
together accounted for 50% of our total revenues during the same period. We
expect that a limited number of advertisers will continue to account for a
significant portion of our revenues. Moreover, we typically sell advertisements
under purchase order agreements. These agreements are subject to cancellation by
our advertisers with no minimum notice requirement. If we lose one or more of
the advertisers that represent a material portion of the revenues we have
generated to date, our business, results of operations and financial condition
would suffer. In addition, if a significant advertiser fails to pay amounts it
owes us, or does not pay those amounts on time, our business, results of
operations and financial condition would suffer. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations."
 
THE SEASONALITY OF OUR ADVERTISING REVENUES COULD CAUSE OUR OVERALL REVENUES TO
FLUCTUATE. We believe that advertising sales in traditional media, such as print
publishing, generally are lower in the first and third calendar quarters of each
year due to buying patterns of advertisers. Therefore, we believe that the
growth of our advertising revenues, which constitute a significant portion of
our total revenues, may be lower in the first and third quarters of each year.
If the Internet makes the transition from an emerging to a more developed
advertising medium, we may experience similar seasonal patterns as those in the
traditional media industry. As a result, our stock price may be lower after the
announcement of our results for the first and third quarters than at other times
of the year.
 
WE DEPEND ON AN EFFECTIVE DIRECT SALES FORCE. We depend on our direct sales
force to sell advertising on our Web sites, e-mail newsletters, online
discussion forums and moderated e-mail discussion lists. We also depend on our
sales force to enter into e-commerce agreements. This dependence involves a
number of risks, including:
 
      -      the need to increase the size of our direct sales force;
 
      -      the need to hire, retain, integrate and motivate additional sales
             and sales support personnel;
 
      -      lack of experience at internet.com of our new sales personnel; and
 
      -      competition from other companies in hiring and retaining sales
             personnel.
 
                                       10
<PAGE>
Our business may suffer if we do not maintain an effective direct sales force.
 
WE FACE INTENSE COMPETITION. The market for Internet-based content offerings and
services is relatively new, intensely competitive and rapidly changing. Since
the advent of commercial services on the Internet, the number of online services
competing for users' attention and spending has proliferated. We expect that
competition will continue to intensify. We compete with other companies that
direct some of their overall Web content and services at the Internet
professional community, such as Ziff-Davis Inc.'s ZDNet, C/NET, Inc., CMP Media
Inc., EarthWeb Inc. and Wired Digital Inc. We also compete for circulation and
advertising impressions with general interest portal and destination Web sites
as well as traditional media.
 
An important part of our strategy is to develop and increase the reputation of
our brand names. If we are unable to do so, or if our competitors develop their
brand names more successfully than we do, our future growth, and our business,
results of operations and financial condition would suffer.
 
Many of our current and potential competitors have longer operating histories,
larger customer bases, greater brand recognition and significantly greater
financial, marketing and other resources than we have. These competitors may be
able to respond more quickly to new or emerging technologies and changes in
customer requirements and to devote greater resources to the development,
promotion and sale of their products and services than we can. We might not be
able to compete successfully against our current or future competitors. See
"Business--Competition."
 
WE MIGHT NOT BE ABLE TO ADEQUATELY MANAGE OUR GROWTH. Our recent growth has
placed, and will continue to place, a significant strain on our managerial,
operational and financial resources. We must continue to implement and improve
our operational and financial systems and to expand, train and manage our
employee base to manage this future growth. We also intend to establish or
acquire additional Web sites, e-mail newsletters, online discussion forums and
moderated e-mail discussion lists which will create additional operational and
management complexities. In addition, we expect that our operational and
management systems will face increased strain as a result of the expansion of
our content offerings and services. We might not be able to manage effectively
the expansion of our operations and systems, and our procedures and controls
might not be adequate to support our operations. In addition, our management
might not be able to make and execute decisions rapidly enough to exploit market
opportunities for the expansion of our content offerings and services. If we are
unable to manage growth effectively, our business, results of operations and
financial condition would suffer.
 
WE MIGHT BE UNABLE TO SUCCESSFULLY IMPLEMENT OUR ACQUISITION STRATEGY. We have
acquired and intend to continue to acquire complementary Web sites, e-mail
newsletters, online discussion forums and moderated e-mail discussion lists,
companies, technologies, services or products as appropriate opportunities
arise. If we identify an appropriate acquisition opportunity, we might not be
able to negotiate the terms of that acquisition successfully, finance it, or
integrate its personnel and operations. We may also have difficulty continuing
to acquire Web sites and other Internet media properties at the prices
historically paid due to the escalation of Internet media valuations. If we make
acquisitions outside of our core business, assimilating the acquired technology,
services or products into our operations could be difficult. This may cause a
disruption in our ongoing business, distract management and make it difficult to
maintain standards, controls and procedures. In addition, we might be required
to incur debt or issue equity securities to pay for any future acquisitions. If
the market price for acquisition targets increases substantially, our future
growth could be harmed.
 
OUR SYSTEMS ARE SUBJECT TO DAMAGE FROM NATURAL DISASTERS, TELECOMMUNICATION
FAILURES, ELECTRONIC BREAK-INS AND SIMILAR PROBLEMS. Most of our communications
and other computer hardware operations are located
 
                                       11
<PAGE>
at our facility in Westport, Connecticut. These systems could be damaged by
fire, floods, earthquakes, power loss, telecommunication failures, electronic
break-ins and similar events. Our network could also be affected by computer
viruses, electronic break-ins or other similar disruptive problems. Any of these
occurrences could harm our business. Our insurance policies have limited
coverage levels and therefore insurance may not adequately compensate us for any
losses that may occur due to any failures or interruptions in our systems. See
"--The failure of computer systems and software products to be Year 2000
compliant could hurt our business" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Year 2000 Compliance."
 
OUR SYSTEMS MAY FAIL OR EXPERIENCE A SLOWDOWN AND OUR USERS DEPEND ON OTHERS FOR
ACCESS TO OUR NETWORK. Our network of Web sites, e-mail newsletters, online
discussion forums and moderated e-mail discussion lists must accommodate a high
volume of traffic and deliver frequently updated information. Our network has in
the past, and may in the future, experience slower response times or decreased
traffic for a variety of reasons. There have been two instances where
internet.com as a whole has been inaccessible, in each instance for
approximately 30 minutes. Slower response times, which have occurred more
frequently, can result from general Internet problems, routing and equipment
problems by third-party Internet access providers, problems with third-party
advertising servers and increased traffic to our servers. We also depend on
information providers to provide information and data feeds on a timely basis.
Our network could experience interruptions in service due to the failure or
delay in the transmission or receipt of this information. In addition, our
community of Internet users depends on Internet service providers, online
service providers and other Web sites' operators for access to our network.
Those providers have experienced outages in the past, and may experience outages
or delays in the future. Moreover, our Internet infrastructure might not be able
to support continued growth of our network. Any of these problems could harm our
business.
 
THE FAILURE OF COMPUTER SYSTEMS AND SOFTWARE PRODUCTS TO BE YEAR 2000 COMPLIANT
WOULD HURT OUR BUSINESS. Our business will suffer if the computer systems we
use, as well as the computer systems used by our Internet users, advertisers and
vendors, do not correctly process the change in year from "99" to "00" on
January 1, 2000. We are working to avoid such problems and to obtain assurances
from our advertisers, vendors and other service providers that they are taking
similar steps. We believe that our computer systems will successfully handle the
Year 2000 issue, but there may be parts of our computer systems and aspects of
the Year 2000 issue, including the potential cost of addressing the Year 2000
issue, that we have failed to consider. If our efforts and the efforts of our
users, advertisers, vendors and other service providers to address the Year 2000
issue are not successful, our business will be harmed. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--Year
2000 Compliance."
 
WE DEPEND ON THE CONTINUED SERVICE OF OUR CHAIRMAN AND CHIEF EXECUTIVE OFFICER,
AND OUR PRESIDENT AND CHIEF OPERATING OFFICER, AND WE FACE INTENSE COMPETITION
FOR PERSONNEL. We depend on the continued service of Alan M. Meckler, our
Chairman and Chief Executive Officer, and Christopher S. Cardell, our President
and Chief Operating Officer. While we maintain key person life insurance for
Messrs. Meckler and Cardell, our business would suffer if we were to lose their
services.
 
We expect that we will need to hire additional personnel in all areas. The
competition for personnel in the Internet industry is intense. Any of our
personnel may terminate their employment at any time for any reason. If we do
not succeed in attracting new personnel or retaining and motivating our current
personnel, our business would be harmed.
 
WE HAVE LIMITED PROTECTION OF OUR INTELLECTUAL PROPERTY. Trademarks, copyrights
and other proprietary rights are important to our success and competitive
position. We seek protection of our editorial content,
 
                                       12
<PAGE>
logos, brands and software relating to our Web sites, e-mail newsletters, online
discussion forums and moderated e-mail discussion lists, but our actions may be
inadequate to protect our trademarks, copyrights and other proprietary rights or
to prevent others from claiming violations of their trademarks and other
proprietary rights. In seeking to protect our trademarks, copyrights and other
proprietary rights, or defending ourselves against claims of infringement
brought by others, with or without merit, we could face costly litigation and
the diversion of our management's attention and resources. This could harm our
business. We are currently involved in proceedings opposing the application of
International Data Group, Inc., or IDG, to register the "internet.com"
trademark. See "Business--Intellectual Property" and "--Legal Proceedings." If
we are unable to successfully oppose this trademark application, we might be
required to cease using the "internet.com" trademark, as a result of which our
business would suffer.
 
THERE ARE A NUMBER OF RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS THAT COULD
HARM OUR BUSINESS. One component of our growth strategy is to further expand
into international markets. We have launched Web sites for Canada, the United
Kingdom, Israel, Australia and Asia. Our international operations are at an
early stage of development and have an extremely limited operating history. In
addition, the markets in which we have undertaken international expansion have
technology and online industries that are less developed than in the United
States.
 
There are risks inherent in doing business in international markets, such as the
following:
 
      -      uncertainty of product acceptance by different cultures;
 
      -      unforeseen changes in regulatory requirements;
 
      -      difficulties in staffing and managing multinational operations;
 
      -      government-imposed restrictions on the repatriation of funds;
 
      -      currency fluctuations;
 
      -      difficulties in finding appropriate foreign licensees or joint
             venture partners; and
 
      -      potentially adverse tax consequences.
 
These factors could harm our ability to successfully operate internationally and
could harm our business.
 
RISKS RELATED TO THE INTERNET INDUSTRY
 
OUR FUTURE RESULTS DEPEND ON CONTINUED GROWTH IN THE USE OF THE INTERNET. Our
market is new and rapidly evolving. Our business could suffer if Internet usage
does not continue to grow. Internet usage may be inhibited for a number of
reasons, including:
 
      -      inadequate network infrastructure;
 
      -      security concerns;
 
      -      inconsistent quality of service;
 
      -      lack of availability of cost-effective and high-speed service; and
 
      -      changes in government regulation of the Internet.
 
                                       13
<PAGE>
If Internet usage grows, the Internet infrastructure might not be able to
support the demands placed on it by this growth or its performance and
reliability may decline. In addition, future outages and other interruptions
occurring throughout the Internet could lead to decreased use of our network and
would therefore harm our business.
 
WE COULD BE SUED FOR INFORMATION RETRIEVED FROM THE INTERNET. We may face
liability for defamation, negligence, copyright or trademark infringement,
personal injury, or other claims due to the nature of content on our network of
Web sites, e-mail newsletters, online discussion forums and moderated e-mail
discussion lists, including content placed on our network by others. Such claims
may also include, among others, claims that by providing hypertext links to Web
sites operated by third parties, we are liable for wrongful actions by those
third parties through such Web sites. Similar claims have been brought, and
sometimes successfully asserted, against online services. It is also possible
that users could make claims against us for losses incurred in reliance on
information provided on our network. Although we carry general liability
insurance, and set forth our terms and conditions of use on our network, our
insurance might not cover potential claims of this type or might not be adequate
to fully protect us. Also, the legal effectiveness of our terms and conditions
of use is uncertain. Any liability or legal defense expenses that are not
covered by insurance would harm our business, results of operations and
financial condition.
 
GOVERNMENT REGULATION AND LEGAL UNCERTAINTIES COULD ADD ADDITIONAL COSTS AND
RISKS TO DOING BUSINESS ON THE INTERNET. There are currently few laws or
regulations that specifically regulate communications or commerce on the
Internet. However, laws and regulations may be adopted in the future that
address issues such as user privacy, pricing and the characteristics and quality
of products and services. For example, although it was held unconstitutional,
the Telecommunications Act of 1996 prohibited certain types of information and
content from being transmitted over the Internet. Several other nations have
taken actions to restrict the free flow of material deemed to be objectionable
on the Internet. In addition, local telephone carriers have argued before the
Federal Communications Commission, or FCC, that Internet service providers and
online service providers should be required to pay fees for access to local
telephone networks in a manner similar to long distance telephone carriers. If
these efforts are successful, costs for Internet access could increase sharply.
Moreover, it may take years to determine the extent to which existing laws
relating to issues such as property ownership, libel and personal privacy are
applicable to the Internet. Any new laws or regulations relating to the Internet
could harm our business.
 
REGULATION COULD REDUCE THE VALUE OF OUR DOMAIN NAMES. We own the Internet
domain name "internet.com," as well as numerous other domain names both in the
United States and internationally. Domain names generally are regulated by
Internet regulatory bodies. The regulation of domain names in the United States
and in foreign countries is subject to change. Regulatory bodies could establish
additional top-level domains, appoint additional domain name registrars or
modify the requirements for holding domain names. As a result, we might not
acquire or maintain the "internet.com" or comparable domain names in all the
countries in which we conduct business, which could harm our business.
Furthermore, the relationship between regulations governing domain names and
laws protecting trademarks and similar proprietary rights is unclear and still
evolving. Therefore, we might be unable to prevent third parties from acquiring
domain names that infringe or otherwise decrease the value of our trademarks and
other proprietary rights. If this occurred, our business would suffer.
 
THE INTERNET INDUSTRY IS CHARACTERIZED BY RAPID TECHNOLOGICAL CHANGE. Rapid
technological developments, evolving industry standards and user demands, and
frequent new product introductions and enhancements characterize the market for
Internet products and services. These market characteristics are exacerbated by
the emerging nature of the market and the fact that many companies are expected
 
                                       14
<PAGE>
to introduce new Internet products and services in the near future. Our future
success will depend on
our ability to continually improve our content offerings and services. In
addition, the widespread adoption of developing multimedia-enabling technologies
could require fundamental and costly changes in our technology and could
fundamentally affect the nature, viability and measurability of Internet-based
advertising, which could harm our business.
 
RISKS RELATED TO THIS OFFERING
 
THERE HAS BEEN NO PUBLIC TRADING MARKET FOR OUR STOCK PRIOR TO THIS OFFERING AND
OUR STOCK PRICE COULD BE EXTREMELY VOLATILE. There has not previously been a
public market for our common stock. We cannot predict the extent to which
investor interest in our company will lead to the development of a trading
market or how liquid any trading market might become. The initial public
offering price for the shares of our common stock will be determined by
negotiations between internet.com and the representatives of our underwriters
and might not reflect prices that will prevail in the trading market. The stock
market has experienced extreme price and volume fluctuations and the market
prices of securities of technology companies, particularly Internet-related
companies, have been highly volatile. Investors might not be able to resell
their shares at or above the initial public offering price. In the past,
following periods of volatility in the market price of a company's securities,
securities class action litigation has often been instituted against such a
company. Such litigation could result in substantial costs and a diversion of
our management's attention and resources.
 
OUR STOCK OWNERSHIP WILL BE CONCENTRATED IN ALAN M. MECKLER, OUR CHAIRMAN AND
CHIEF EXECUTIVE OFFICER. As of March 31, 1999, the present directors, executive
officers, greater than 5% stockholders and their affiliates beneficially owned
approximately 80.8% of our outstanding common stock, after giving effect to this
offering. As of March 31, 1999, Alan M. Meckler beneficially owned approximately
55.2% of our outstanding common stock, after giving effect to this offering. As
a result of his beneficial ownership, Mr. Meckler, acting alone or with others,
will be able to control all matters requiring stockholder approval, including
the election of directors and approval of significant transactions. This
concentration of ownership may also have the effect of delaying or preventing a
change in control of internet.com. See "Principal and Selling Stockholders."
 
OUR CHARTER DOCUMENTS AND THE DELAWARE GENERAL CORPORATION LAW MAY INHIBIT A
TAKEOVER. Our Amended and Restated Certificate of Incorporation, bylaws and the
Delaware General Corporation Law could make it more difficult for a third party
to acquire us, even if a change in control would be beneficial to our
stockholders. Our Amended and Restated Certificate of Incorporation allows our
board of directors to issue preferred stock which may have rights and
preferences that are superior to those of our common stock, thereby deterring a
potential acquiror. Our bylaws provide that a special meeting of stockholders
may only be called by our Board, Chairman of the Board, Chief Executive Officer
or President or at the request of the holders of a majority of the outstanding
shares of our common stock. See "Description of Capital Stock--Delaware
Anti-takeover Law and Certain Charter and Bylaw Provisions."
 
SHARES ELIGIBLE FOR PUBLIC SALE AFTER THIS OFFERING WOULD HURT OUR STOCK PRICE.
After this offering there will be outstanding 23,400,000 shares of our common
stock. Of these shares, the shares sold in this offering will be freely
tradeable except for any shares purchased by our "affiliates" as that term is
defined in Rule 144 under the Securities Act of 1933, as amended. The remaining
20,000,000 shares held by our directors, officers, employees, current outside
stockholders, greater than 5% stockholders and their affiliates will be
"restricted securities" and will become eligible for sale on the first
anniversary of the closing of this offering, subject to the volume limitations
and other conditions of Rule 144. In addition, 180 days after this offering, at
least 13,500 shares will be issuable upon the exercise of options (based
 
                                       15
<PAGE>
on options outstanding as of May 18, 1999). Sales of a large number of shares
would hurt the market price for our common stock. See "Certain Transactions" and
"Shares Eligible for Future Sale."
 
None of our directors, officers or greater than 5% stockholders has any
restrictions on selling any of our securities held by him or her, other than as
provided in lock-up agreements with U.S. Bancorp Piper Jaffray Inc., William
Blair & Company, L.L.C. and DLJDIRECT Inc. and under applicable securities laws.
In addition, Internet World Media, a wholly-owned subsidiary of Penton Media,
can require us to register its shares of our common stock for public sale if we
register any more of our equity securities after this offering (with some
exceptions, such as if we register securities issuable under our stock incentive
plan). Any sales by Internet World Media following this offering could hurt the
trading price of our common stock. See "Certain Transactions--Registration
Rights Agreement" and "Shares Eligible for Future Sale."
 
   
YOU WILL INCUR IMMEDIATE DILUTION IN THIS OFFERING. The initial public offering
price of our common stock is substantially higher than the net tangible book
value per share of the outstanding common stock immediately after this offering.
Therefore, if you purchase our common stock in this offering, you will incur
immediate dilution of $9.46 in the net tangible book value per share of common
stock from the price you pay for such common stock (based upon an assumed
initial public offering price of $11.00 per share). See "Dilution."

<PAGE>
                                USE OF PROCEEDS
 
   
The net proceeds from the sale of the 3,400,000 shares of our common stock
offered by internet.com are estimated to be $33.5 million. This assumes an
initial public offering price of $11.00 per share and also reflects a deduction
for the estimated underwriting discounts and commissions and estimated offering
expenses. The principal purposes of this offering are to obtain additional
capital, create a public market for internet.com common stock and facilitate our
future access to the public capital markets.
    
 
We intend to use a portion of the net proceeds for repayment of debt incurred
under our line of credit agreement (approximately $3.1 million as of April 30,
1999). This debt matures on November 15, 1999 and bears interest at a rate based
on the lower of prime plus 1% or LIBOR plus .65% (5.7% as of April 30, 1999). We
expect to use the remainder of the net proceeds for potential strategic
acquisitions and general corporate purposes, including working capital and
expansion of editorial, marketing and sales activities. The amounts actually
expended for such working capital purposes may vary significantly and will
depend on a number of factors, including the amount of our future revenues and
the other factors described under "Risk Factors." Accordingly, our management
will retain broad discretion in the allocation of the net proceeds of this
offering. Pending such uses, the net proceeds of this offering will be invested
in short-term, interest-bearing, investment grade securities.
 
                                DIVIDEND POLICY
 
We have not in the past paid any dividends on our equity securities and
anticipate that we will retain any future earnings for use in the expansion and
operation of our business. We do not anticipate paying any cash dividends in the
foreseeable future. Any determination to pay dividends in the future will be at
the discretion of our board of directors and will depend upon our financial
condition, results of operations and capital requirements.

The following table sets forth our historical capitalization (assuming the
conversion of internet.com LLC into internet.com Corporation) as of March 31,
1999, which has been adjusted, on a pro forma basis, to reflect the sale of
3,400,000 shares of common stock offered hereby at an assumed offering price of
$11.00 per share and the exercise by Internet World Media of its warrant to
purchase 2,075,634 shares of our common stock immediately prior to the closing
of this offering.

                                    DILUTION
 
   
Our net tangible book value as of March 31, 1999, assuming the conversion of
internet.com LLC into internet.com Corporation as of that date, was $(539,000),
or $(0.03) per share of common stock. Pro forma net tangible book value per
share represents the amount of total tangible assets less total liabilities,
divided by the pro forma shares of common stock outstanding as of March 31,
1999. Our pro forma net tangible book value as of March 31, 1999 would have been
$36.0 million, or $1.54 per share. These amounts reflect the issuance and sale
of our common stock offered hereby at an assumed initial public offering price
of $11.00 per share and deductions for estimated underwriting discounts,
commissions and offering expenses, and the exercise by Internet World Media of
its warrant to purchase 2,075,634 shares of our common stock immediately prior
to the closing of this offering for a total of $3.0 million. This represents an
immediate increase in pro forma net tangible book value of $1.57 per share to
existing stockholders and an immediate dilution of $9.46 per share to new
investors. The following table illustrates this per share dilution:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
The following discussion should be read in conjunction with our financial
statements and the accompanying notes which appear elsewhere in this prospectus.
This prospectus contains forward-looking statements that involve risks and
uncertainties. These statements relate to our future plans, objectives, beliefs,
expectations and intentions. These statements may be identified by the use of
words such as "expects," "anticipates," "believes," "intends," "plans" and
similar expressions. Our actual results could differ materially from those
discussed in these statements. Factors that could cause or contribute to these
differences include those discussed below and in "Risk Factors" and elsewhere in
this prospectus.
 
OVERVIEW
 
We own and operate a leading network of integrated business-to-business vertical
content Web sites, e-mail newsletters, online discussion forums and moderated
e-mail discussion lists focused solely on the Internet industry. Our network
consists of nine integrated business-to-business vertical content channels that
contain 61 Web sites, 43 e-mail newsletters, 55 online discussion forums and 52
moderated e-mail discussion lists focused solely on the Internet industry.
During the month of April 1999, we delivered 42.1 million page views to
approximately 1.7 million unique visitors and 8.1 million copies of our e-mail
newsletters to 700,000 subscribers, and 31.2 million postings were generated by
51,000 subscribers to our moderated e-mail discussion lists.
 
We were formed in November 1998 following the acquisition of Mecklermedia by
Penton Media. As part of the acquisition, Penton Media agreed to contribute all
the assets of Mecklermedia's Internet media business division, iWorld, to a
newly formed limited liability company, internet.com LLC. As part of this
acquisition agreement, we reserved 4% of our total membership units for
discretionary grants to our employees. The grants were completed in March 1999,
at which time the fair value of the membership units granted was $1.6 million.
As these membership units will vest upon the completion of an initial public
offering, we will record a $1.6 million compensation charge concurrent with the
completion of this offering. Prior to the acquisition of Mecklermedia by Penton
Media, iWorld operated as one of three business lines which comprised
Mecklermedia. Our predecessor Web sites, MecklerWeb and iWorld.com, were also
dedicated to covering Internet developments. See "Certain
Transactions--Formation Transactions."
 
We generate revenues from the following primary sources:
 
      -      advertising on our Web sites, e-mail newsletters, online discussion
             forums and moderated e-mail discussion lists;
 
      -      e-commerce agreements;
 
      -      paid subscription services; and
 
      -      licensing of our editorial content, brands and software.
 
We barter portions of the unsold advertising impressions generated by our
network for advertising and promotion in media properties owned by Penton Media
and other third parties. We do not record any revenues or expenses for such
barter because we do not receive or expend any cash, nor do we incur any costs
to fulfill such barter, and because such unsold advertising impressions would
otherwise have no value. Therefore, the recording of any barter would result in
an overstatement of revenues and expenses. We also believe that not recording
any revenues or expenses for barter more accurately
 
                                       21
<PAGE>
reflects our actual results of operations and as a result provides a more
meaningful presentation to the users of our financial statements.
 
   
For the three months ended March 31, 1999, approximately 87% of our revenues
were from the sale of advertising. We recognize advertising revenue ratably in
the period the advertising is displayed, provided that no significant company
obligations remain outstanding and collection of the resulting receivable is
probable. Such obligations typically include guarantees of a minimum number of
advertising impressions, or times an advertisement is displayed. We use a direct
sales force to sell advertising to companies and advertising agencies.
    
 
Our e-commerce agreements generally include advertising on our Web sites or
revenue sharing for sales made by the e-commerce vendors as a result of links
from our network, or in some cases both advertising and revenue sharing. We
recognize the advertising component of these agreements ratably in the period
the advertising is displayed, provided that no significant company obligations
remain and collection of the remaining receivable is probable. We recognize the
revenue sharing component of these agreements as revenue in the period that the
underlying sales are made by the e-commerce vendor.
 
Paid subscription services relate to customer subscriptions to our paid e-mail
newsletters, Internet Stock Report's Monthly HotWatch, Internet StockTracker and
SearchEngineWatch, which are sold through our network and through affiliate
relationships. Revenue from subscriptions is recognized ratably over the
subscription period. Deferred revenues relate to the portion of collected
subscription fees which has not yet been recognized as revenue.
 
Our licensing agreements vary in structure, with internet.com generating fixed
fees, royalties or both for access to our editorial content, brands or software.
We generally license our editorial content, brands and software to offline and
online media companies.
 
Since July 1995, we have made 28 acquisitions of Internet media properties,
consisting of 37 Websites, 29 e-mail newsletters, 16 online discussion forums
and four moderated e-mail discussion lists. We have made 17 of these 28
acquisitions since March 1, 1998. We expect to continue to pursue strategic
acquisitions to strengthen our content, community and commerce offerings.
 
We believe that advertising sales in traditional media, such as print
publishing, generally are lower in the first and third calendar quarters of each
year due to buying patterns of advertisers. If the Internet makes the transition
from an emerging to a more developed advertising medium, we may experience
similar seasonal patterns as those in the traditional media industry. See "Risk
Factors--The seasonality of our advertising revenues could cause our overall
revenues to fluctuate."
 
We have sustained losses on a quarterly and annual basis in the past. We expect
to incur significantly higher costs, particularly advertising, promotion and
selling expense, to grow our business. As a result, we expect to incur
significant operating losses for the foreseeable future and because costs are
largely fixed in the short term, we expect to be vulnerable to significant
fluctuations in operating losses if actual revenues fall below anticipated
levels. Furthermore, given the rapidly evolving nature of our business and our
limited operating history, our operating results are difficult to forecast and
period-to-period comparison of our operating results will not be meaningful and
should not be relied upon as any indication of future performance. Due to these
and other factors, many of which are outside our control, quarterly operating
results may fluctuate significantly in the future. See "Risk Factors--We have a
limited operating history," "--We anticipate continued losses" and "--Our
quarterly operating results are subject to significant fluctuations."

RESULTS OF OPERATIONS
 
Costs have been allocated to the iWorld division of Mecklermedia based on our
management's estimate of the costs attributable to its operations. Such
allocations are not necessarily indicative of the costs that would have been
incurred if the iWorld division of Mecklermedia had been a stand-alone entity.
The following table sets forth certain statement of operations data as a
percentage of revenues for the periods indicated:

THREE MONTHS ENDED MARCH 31, 1998 AND 1999
 
REVENUES. We generate revenues from advertising on our Web sites, e-mail
newsletters, online discussion forums and moderated e-mail discussion lists;
e-commerce agreements; licensing of our editorial content, brands and software;
and paid subscription services. Revenues were $831,000 for the three months
ended March 31, 1998 and approximately $1.6 million for the three months ended
March 31, 1999, representing an increase of 94%. This increase was primarily due
to increased advertising on our network of Web sites, e-mail newsletters, online
discussion forums and moderated e-mail discussion lists. While we anticipate
that advertising revenues will continue to represent a substantial majority of
our revenues for the foreseeable future, we believe that revenues from e-
commerce agreements, licensing, paid subscription services, seminars, opt-in
e-mail list rentals and venture fund management will expand and diversify our
future revenue streams.
 
COST OF REVENUES. Cost of revenues primarily consists of expenses associated
with editorial, communications infrastructure and Web site hosting. Cost of
revenues was $567,000 for the three months ended March 31, 1998 and
approximately $1.1 million for the three months ended March 31, 1999,
representing an increase of 97%. This change was primarily due to the increased
hiring of editorial, technology and operations personnel and expenses for
freelance contributors. As a percentage of revenues, cost of revenues was 68%
for the three months ended March 31, 1998 and 69% for the three months ended
March 31, 1999. We anticipate that our cost of revenues will continue to
increase in absolute dollars as we continue to strengthen our existing content
offerings and services. We anticipate hiring additional editorial, technology
and operations personnel, as well as freelance
 
                                       23
<PAGE>
contributors, as we acquire additional Web sites, e-mail newsletters, online
discussion forums and moderated e-mail discussion lists and expand our
proprietary content.
 
ADVERTISING, PROMOTION AND SELLING. Advertising, promotion and selling expenses
primarily consist of costs related to sales and marketing staff, sales
commissions and promotion costs. Advertising, promotion and selling expenses
were $283,000 for the three months ended March 31, 1998 and $928,000 for the
three months ended March 31, 1999, representing a 228% increase. This change was
primarily due to increased hiring of advertising sales personnel. As a
percentage of revenues, advertising, promotion and selling expenses were 34% for
the three months ended March 31, 1998 and 58% for the three months ended March
31, 1999. We anticipate that our advertising, promotion and selling expenses
will continue to increase in absolute dollars, primarily due to our planned
hiring of additional sales personnel in an effort to increase our advertising
sales as well as increased expenses for the promotion of our content offerings
and services to our community of Internet users, advertisers and vendors.
 
GENERAL AND ADMINISTRATIVE. General and administrative expenses primarily
consist of salaries, professional fees, facilities costs and bad debt expense.
General and administrative expenses were $348,000 for the three months ended
March 31, 1998 and $773,000 for the three months ended March 31, 1999,
representing a 122% increase. This change was primarily due to the hiring of
additional personnel and increased professional fees. As a percentage of
revenues, general and administrative expenses were 42% for the three months
ended March 31, 1998 and 48% for the three months ended March 31, 1999. We
expect that our general and administrative expenses will continue to increase in
absolute dollars, but these expenses are expected to decrease as a percentage of
revenues. We anticipate hiring additional personnel and incurring additional
costs related to being a public company, including directors' and officers'
liability insurance, investor relations programs and professional services fees.
 
DEPRECIATION AND AMORTIZATION. Depreciation of property and equipment was
$102,000 for the three months ended March 31, 1998 and $82,000 for the three
months ended March 31, 1999, representing a 20% decrease. As a percentage of
revenues, depreciation of property and equipment was 12% for the three months
ended March 31, 1998 and 5% for the three months ended March 31, 1999.
Amortization of intangibles was $222,000 for the three months ended March 31,
1998 and approximately $1.9 million for the three months ended March 31, 1999,
representing a 742% increase. This increase was primarily due to the
amortization of the goodwill associated with the formation of internet.com LLC.
As a percentage of revenues, amortization of intangibles was 27% for the three
months ended March 31, 1998 and 116% for the three months ended March 31, 1999.
We anticipate that depreciation and amortization will continue to increase as we
acquire additional Web sites, e-mail newsletters, online discussion forums and
moderated e-mail discussion lists. We also anticipate increasing our capital
expenditures to support the current and expected growth of our business.
 
INTEREST EXPENSE, NET. Interest expense, net of interest income, related to
borrowings under our line of credit was $32,000 for the three months ended March
31, 1999.

1998. As a percentage of revenues, amortization of intangibles was 73% for the
period from November 24, 1998 through December 31, 1998.
 
PURCHASED IN-PROCESS RESEARCH AND DEVELOPMENT. In connection with our formation
on November 24, 1998, we recorded a $2.0 million charge for purchased in-process
research and development projects initiated by our predecessor entity that had
not reached technological feasibility and had no probable alternative future
uses. This amount, which was determined by an independent appraiser, was
expensed at our date of inception. Management believes that the assumptions used
in the independent appraiser's valuation of the purchased in-process research
and development are reasonable. However, no assurance can be given that
commercial or technological viability of these projects will be achieved or that
actual results will not deviate from those assumptions in future periods.

borrowings under our line of credit was $8,000 for the period from November 24,

$67,000 for the period from October 1, 1998 through November 23, 1998. As a
percentage of revenues, depreciation of property and equipment was 8% for the
period from October 1, 1998 through November 23, 1998. Amortization of

from fiscal 1996 to fiscal 1997 and 140% from fiscal 1997 to fiscal 1998. The
197% increase from fiscal 1996 to fiscal 1997 was primarily due to an increase

    Corporation.

Our revenues have increased sequentially from quarter to quarter throughout the
periods since January 1, 1997 due to increased advertising on our network of Web
sites, e-mail newsletters, online
 
                                       27

discussion forums and moderated e-mail discussion lists. Quarterly revenues and
operating results depend substantially upon the advertising revenues received
within the quarter, which are difficult to forecast accurately. Accordingly, the
cancellation or deferral of a small number of advertising contracts could harm
our business, results of operations and financial condition. We believe that
advertising sales in traditional media, such as print publishing, generally are
lower in the first and third calendar quarters of each year due to buying
patterns of advertisers. If the Internet makes the transition from an emerging
to a more developed medium, we may experience similar seasonal patterns as those
in the traditional media industry. As a result, our stock price may be lower
after the announcement of our results for the first and third quarters than at
other times of the year.
 
Due to the foregoing factors, quarterly revenues and results of operations are
difficult to forecast. We do not believe that period-to-period comparison of our
operating results will necessarily be meaningful, and they should not be relied
upon as indicators of future performance. In one or more future quarters,
results of operations may fall below the expectations of securities analysts and
investors. In such event, the trading price of our common stock could decrease
significantly.
 
LIQUIDITY AND CAPITAL RESOURCES
 
Since inception, we have funded operations primarily with cash from borrowings
under our line of credit, the capital contributions of members of internet.com
LLC and cash from revenues. As of March 31, 1998, internet.com had total current
assets of $2.4 million and total current liabilities of $4.6 million, or a
working capital deficit of $2.2 million.
 
Net cash used in operating activities was approximately $1.1 million for the
year ended September 30, 1996, $1.1 million for the year ended September 30,
1997, $1.8 million for the year ended September 30, 1998, $1.4 million for the
period from October 1, 1998 through November 23, 1999, $612,000 for the period
from November 24, 1998 through December 31, 1998, $495,000 for the three months
ended March 31, 1998 and $73,000 for the three months ended March 31, 1999. Net
cash used in operating activities was primarily a result of our net losses
adjusted for non-cash depreciation, amortization and purchased in-process
research and development, and increases in accounts receivable, offset by an
increase in accounts payable and accrued expenses.
 
Net cash used in investing activities was approximately $642,000 for the year
ended September 30, 1996, $2.4 million for the year ended September 30, 1997,
$5.0 million for the year ended September 30, 1998, $2.5 million for the period
from October 1, 1998 through November 23, 1998, $1.1 million for the period from
November 24, 1998 through December 31, 1998, $1.4 million for the three months
ended March 31, 1998 and $1.5 million for the three months ended March 31, 1999.
Net cash used in investing activities was primarily a result of acquisitions of
Web sites and related Internet media properties and capital expenditures.
 
Net cash provided by financing activities was approximately $1.8 million for the
year ended September 30, 1996, $3.5 million for the year ended September 30,
1998, $3.9 million for the period from October 1, 1998 through November 23,
1998, $1.9 million for the period from November 24, 1998 through December 31,
1998, $1.9 million for the three months ended March 31, 1998 and $1.6 million
for the three months ended March 31, 1999. Net cash provided by financing
activities was a result of borrowings under our line of credit, a private
placement of equity securities and contributions from Mecklermedia.
 
Capital expenditures were $315,000 for the year ended September 30, 1996,
$740,000 for the year ended September 30, 1997, $934,000 for the year ended
September 30, 1998, $91,000 for the period from October 1, 1998, through
November 23, 1998, $546,000 for the period from November 24, 1998
 
                                       28
<PAGE>
through December 31, 1998, $178,000 for the three months ended March 31, 1998
and $370,000 for the three months ended March 31, 1999. We anticipate that we
will increase our capital expenditures consistent with our anticipated growth in
operations, infrastructure and personnel.
 
We have a $6.0 million line of credit with a bank secured by a personal
guarantee from Alan M. Meckler, our Chairman and Chief Executive Officer. We had
outstanding borrowings under the line of credit of approximately $1.9 million as
of March 31, 1999. Interest expense on this line is based on the lower of prime
plus 1% or LIBOR plus .65% (5.7% as of March 31, 1999). This line of credit
expires on November 15, 1999. Upon completion of this offering, we anticipated
terminating this line of credit.
 
We believe that the net proceeds from this offering and our cash from revenues
will be sufficient to meet our anticipated cash needs for working capital and
capital expenditures for at least 12 months following this offering. Thereafter,
if cash generated from operations is insufficient to satisfy our liquidity
requirements, we might need to raise additional funds through public or private
financing, strategic relationships or other arrangements. There can be no
assurance that such additional funding, if needed, will be available on terms
which we believe are attractive to internet.com, or at all. If we fail to raise
capital when needed, it could harm our business, operating results and
finanacial condition. If we raise additional funds through the issuance of
equity securities, the percentage ownership of our stockholders would be
reduced.
 
YEAR 2000
 
The Year 2000 issue is the potential for system and processing failures of
date-related data as a result of computer-controlled systems using two digits
rather than four to define the applicable year. For example, computer programs
that have time-sensitive software may recognize a date using "00" as the year
1900 rather than the year 2000. This could result in system failure or
miscalculations causing disruptions of operations, including, among other
things, an inability to process transactions, send invoices or engage in similar
normal business activities. We may be affected by Year 2000 issues related to
non-compliant information technology systems or non-information technology
systems operated by us or third parties. Our information technology systems
consist of software and data developed either in-house or purchased from third
parties, and hardware purchased from vendors.
 
STATE OF READINESS. We have completed a preliminary assessment of our
information technology systems, which includes but is not limited to the
hardware and software necessary to provide and deliver our services. We are
continuing to perform assessments of our non-information technology systems,
which include many of the building and office equipment systems. To date, our
assessment has consisted of the following steps:
 
      -      identifying and evaluating all software and hardware upon which we
             are dependent;
 
      -      contacting third-party vendors of hardware, software and services
             that we utilize;
 
      -      contacting material non-information technology systems and service
             providers; and
 
      -      developing and formalizing procedures to implement necessary
             remedial measures.
 
As of the end of the first quarter of 1999 we have performed the following:
 
      -      our management has reviewed all functional areas of our business
             and has identified various systems and software programs that are
             not Year 2000 compliant;
 
      -      we will continue to perform Year 2000 simulations on our systems
             and services to test our system and service readiness;
 
                                       29
<PAGE>
      -      we have revised and continue to revise our systems as necessary to
             improve their Year 2000 compliance based on the results of our Year
             2000 simulation tests;
 
      -      we are continuing to upgrade and test all other hardware and
             software used in our operations;
 
      -      we have identified all vendors of material hardware and software
             components of our information technology systems, have contacted
             our principal vendors of hardware, software and data providers, and
             have obtained confirmation from these vendors, either in writing or
             from information available on their Web sites, regarding their Year
             2000 compliance;
 
      -      our management is continuing the process of working with our
             hardware and software providers to assure that we are prepared for
             the Year 2000; and
 
      -      we are currently assessing our non-information technology systems.
 
At this point in our assessment, we are not currently aware of any Year 2000
problems relating to these systems which would have a material effect on our
business, financial condition or results of operations. We plan to complete our
Year 2000 assessment during the summer of 1999.
 
COST. To date, we have not incurred any material costs in connection with
identifying and evaluating Year 2000 compliance issues. Most of our expenses
have been related to, and are expected to continue to relate to, the operating
costs associated with time spent by employees in the evaluation process and Year
2000 compliance matters. At this time, we do not possess the information
necessary to estimate the potential costs of the replacement of third party
software, hardware or services that are determined not to be Year 2000
compliant. Although we do not anticipate those amounts will be material, if such
expenses are higher than anticipated, our business, financial condition and
operating results would suffer.
 
RISKS. Although our assessment may be finalized without identifying any
additional material non-compliant information technology or systems operated by
us or by third parties, a systemic failure beyond our control, such as a
prolonged telecommunications or electrical failure, is possible. This type of
failure could prevent us from operating our business, prevent users from
accessing our network, or change the behavior of advertising customers or
persons accessing our network. We believe that the primary business risks, in
the event of such failure, would include but not be limited to lost advertising
revenues, lost business revenues, increased operating costs, loss of customers
or persons accessing our network and servers, or other business interruptions of
a material nature, as well as claims of mismanagement, misrepresentation or
breach of contract.
 
CONTINGENCY PLAN. As discussed above, we are engaged in an ongoing Year 2000
assessment. The results of our further testing and the responses we receive from
third-party vendors, service providers and customers will be taken into account
in determining the nature and extent of any contingency plans.
 
QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKS
 
We are exposed to market risk from changes in interest rates on borrowings under
our line of credit that bears interest from time to time at the lower of the
lending bank's prime rate plus 1% or LIBOR plus .65%. Because we do not believe
that the maximum available borrowings under the line of credit are material, and
because we anticipate terminating this line of credit upon the completion of
this offering, we do not believe this risk will be material.

We have no derivative financial instruments or derivative commodity instruments
in our cash and cash equivalents and investments. We invest our cash and cash
equivalents and investments in short-term, interest-bearing, investment grade
securities. We anticipate investing our net proceeds from this offering in
similar investment grade investments pending their use as described in this
prospectus. See "Use of Proceeds." Our transactions are generally conducted, and
our accounts are denominated, in United States dollars. Accordingly, we are not
exposed to significant foreign currency risk.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
In June 1997, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards No. 131, "Disclosures about Segments of an
Enterprise and Related Information" ("SFAS No. 131"), which establishes
standards for reporting information about operating segments in annual financial
statements. It also establishes standards for related disclosures about products
and services, geographic areas and major customers. SFAS No. 131 is effective
for fiscal years beginning after December 15, 1997. The adoption of this
standard is not expected to have an impact on the presentation of our financial
statements.
 
In March 1998, the American Institute of Certified Public Accountants ("AICPA")
issued Statement of Position 98-1, "Accounting for the Cost of Computer Software
Developed or Obtained for Internal Use" ("SOP 98-1"). SOP 98-1 is effective for
financial statements for years beginning after December 15, 1998. SOP 98-1
provides guidance over accounting for computer software developed or obtained
for internal use including the requirement to capitalize specified costs and
amortization of such costs. The adoption of this standard is not expected to
have a material effect on our capitalization policy.
 
In April 1998, the AICPA issued Statement of Position 98-5, "Reporting on the
Costs of Start-Up Activities" ("SOP 98-5"). SOP 98-5, which is effective for
fiscal years beginning after December 15, 1998, provides guidance on the
financial reporting of start-up costs and organization costs. It requires costs
of start-up activities and organization costs to be expensed as incurred. As we
have expensed these costs historically, the adoption of this statement is not
expected to have a significant impact on our results of operations, financial
position or cash flows.

700,000 subscribers, and 31.2 million postings were generated by 51,000
subscribers to our moderated e-mail discussion lists.
 
INDUSTRY BACKGROUND
 
GROWTH OF THE INTERNET.  The Internet has emerged as a global distribution
network for real-time news and information, an environment for online
communities and a market place in which commerce is conducted. IDC estimates
that the number of Internet users will grow from 159 million in 1998 to 509
million in 2003 and estimates that the number of URLs will grow from
approximately 925 million in 1998 to 13.1 billion in 2003. To best exploit the
rapid growth of the Internet, businesses must stay abreast of Internet-related
technologies and products as well as develop and maintain the skills necessary
to utilize these technologies and products. A broader set of executive
management and business professionals are increasingly participating in Internet
technology implementation decisions with information technology professionals.
As a result, Internet-related topics need to be addressed from a variety of
business as well as technology perspectives to effectively communicate the value
of deploying and integrating Internet technologies.
 
The increasing use of the Internet is dramatically affecting the operating
methods of profit and not-for-profit businesses and other organizations. These
businesses and organizations are dedicating an increasing amount of personnel
and financial resources to integrating and effectively using the Internet to
expand and enhance their operations. As a result, these businesses and
organizations have a rapidly growing need for personnel with specialized skills
and knowledge in Internet technologies who can effectively build and manage
their Internet infrastructures.
 
NEED FOR A COMPREHENSIVE RESOURCE FOR INTERNET INDUSTRY AND INTERNET TECHNOLOGY
PROFESSIONALS. With the rapid change and increasing complexity of Internet
technology and the industries surrounding it, Internet industry and Internet
technology professionals need a comprehensive resource to provide the most
recent Internet news and information as well as tutorials in Internet
technologies. To date, these professionals have relied upon general business and
information technology publishers, software and hardware vendors and training
service providers to stay abreast of the latest Internet industry
 
                                       32
<PAGE>
developments and Internet technology trends. We believe these traditional
resources are inadequate for Internet professionals for several reasons,
including an inability to provide real-time Internet news and information,
training in the latest Internet technologies and communities focused on specific
interests.
 
Internet industry and Internet technology professionals have developed a
critical need for a timely and comprehensive resource that provides a broad
range of independent, in-depth and easy-to-access content to keep them
up-to-date in the rapidly evolving Internet industry. Internet industry and
Internet technology professionals require current information covering Internet
business and technical information, including:
 
      -      news;
 
      -      analysis;
 
      -      tutorials, training and skills development;
 
      -      market information about emerging products and technologies;
 
      -      buyers' guides and product reviews;
 
      -      Internet market research; and
 
      -      expert advice.
 
These professionals also need a focused online community to share information
with one another, work together to find solutions to common problems, learn
about upcoming conferences and other industry events, seek employment and hire
personnel. In addition, Internet industry and Internet technology professionals
are frequently responsible for purchasing Internet technologies for their
companies. In order to make informed purchasing decisions, these professionals
must devote considerable time, effort and financial resources to researching new
Internet technologies. To date, they have had to rely on fragmented and
disparate sources, such as technical books and print magazines, and training
materials provided by service providers and traditional software retailers. None
of these sources has provided a comprehensive and timely solution for Internet
professionals' need for content, community and commerce.
 
NEED FOR ADVERTISERS AND VENDORS TO REACH INTERNET INDUSTRY AND INTERNET
TECHNOLOGY PROFESSIONALS. Advertisers and vendors have realized that Internet
industry and Internet technology professionals represent a highly attractive
audience and need a medium through which they can reach this audience in a
focused and effective manner. Internet advertising permits advertisers to gather
demographic information, through voluntary registration and user surveys, and
direct messages at targeted groups of users. It also enables advertisers to
measure the effectiveness of their advertising campaigns and revise them in
response to real-time feedback, market factors and current events. Traditional
forms of advertising are not as targeted and do not permit evaluation of results
in as timely and accurate a manner. Internet advertising is growing rapidly and
is projected to experience significant growth in the future. Forrester Research,
Inc. estimates that:
 
      -      worldwide Internet advertising will grow from $1.5 billion in 1998
             to $10.9 billion in 2002; and
 
      -      business-to-business Internet advertising will grow from $290
             million in 1998 to $2.6 billion in 2002.
 
Vendors of goods and services via the Internet benefit from the ability to reach
a global audience and to operate with minimal physical infrastructure, reduced
overhead and greater economies of scale. The number of transactions taking place
over the Internet is growing rapidly and is expected to increase as
 
                                       33
<PAGE>
vendors improve Internet-based transaction processing technology and as
consumers become more accustomed to buying online. Forrester Research estimates
that:
 
      -      e-commerce will grow from $55 billion in 1998 to $1.1 trillion in
             2002; and
 
      -      business-to-business e-commerce will grow from $17 billion in 1998
             to $327 billion in 2002.
 
In summary, the evolution and growth of the Internet has created a rapidly
expanding group of Internet professionals with a critical need for timely
content, community and commerce resources. These Internet professionals
represent a select, focused and attractive group of potential purchasers for
advertisers and vendors to target.

             categorized by vertical content areas for the Internet industry,
             that enable users to share information and resources in order to

                                       34
<PAGE>
      -      MODERATED E-MAIL DISCUSSION LISTS. We offer 52 moderated e-mail
             discussion lists and have over 51,000 subscribers to these lists,

             searchable formats.
 
      -      TECHNICAL JOB LISTINGS. Through SILICONALLEYJOBS.COM and an
             agreement with CareerBuilder, Inc., JOBS.INTERNET.COM, we provide
             our community of Internet users with access to Internet industry

BENEFITS FOR ADVERTISERS AND VENDORS
 
We provide advertisers and vendors with targeted channels to reach our highly
focused community of Internet users, many of whom either make or influence
purchasing decisions. We believe that our Internet users represent a large,
targeted and highly influential online community of Internet industry and
Internet technology professionals, Web developers and experienced Internet
users. We believe our advertisers and vendors can enhance the effectiveness of
their advertising by customizing advertisements and placing them on targeted
channels and pages on our network. We also provide vendors with a much needed
distribution channel and the ability to focus their marketing efforts cost
effectively.
 
Our Web sites, e-mail newsletters, online discussion forums and moderated e-mail
discussion lists attract a focused community of business and professional
Internet users, as compared to more broadly focused Web sites. According to a
survey we commissioned from Informative LLC, which was
 
                                       35
<PAGE>
conducted from August 1998 through February 1999, some key demographics of our
community of Internet users include:
 
      -      83% are involved in purchasing Internet products and services for
             their companies and organizations, including hardware, software,
             networking and Internet access;
 
      -      67% purchased products online in the six months ended February 28,
             1999;
 
      -      53% have Internet technology or information technology job titles;
             another 19% are in corporate management;
 
      -      the average household income of the group exceeds $65,000 annually;
 
      -      61% are in the desirable 25-44 age group; and
 
      -      72% have at least one college degree.
 
OUR BUSINESS STRATEGY
 
Our objective is to maintain and strengthen our position as a provider of
integrated, business-to-business vertical content focused solely on the Internet
industry. We intend to achieve this objective by continuing to execute the
following key strategies:
 
INCREASE OUR PROPRIETARY CONTENT OFFERINGS AND SERVICES. We will strengthen our
existing content offerings and services by continuing to improve our proprietary
content available for our community of Internet users. Our editorial team,
comprised of 33 employees and over 50 freelance contributors as of April 30,
1999, creates proprietary content for our network on a daily basis. In April
1999, our editorial team authored more than 700 news articles published in
InternetNews, over 50 technical tutorials, over 140 product or book reviews and
various other publications. We will continue to identify emerging topics of
interest and then create and aggregate content for those topics through internal
development and acquisitions of additional Web sites, e-mail newsletters, online
discussion forums and moderated e-mail discussion lists.
 
GROW THROUGH TARGETED ACQUISITIONS. Since July 1995, we have made 28
acquisitions, which included 37 Web sites, 29 e-mail newsletters, 16 online
discussion forums and four moderated e-mail discussion lists. Since March 1,
1998, we have made 17 acquisitions, which included 26 Web sites, 22 e-mail
newsletters, nine online discussion forums and three moderated e-mail discussion
lists. We expect to continue to pursue strategic acquisitions to strengthen our
content, community and commerce offerings. We may also acquire Internet media
properties to obtain valuable brands, expertise or access to new users,
advertisers and vendors. We believe that by acquiring Internet media properties,
we can integrate them into our network and improve their traffic and revenue
results. In addition, we believe that acquiring Web sites, e-mail newsletters,
online discussion forums and moderated e-mail discussion lists generally has
increased the overall traffic on our existing network. We intend to use our
experience gained from our numerous acquisitions in order to identify, evaluate,
acquire and integrate Web sites, e-mail newsletters, online discussion forums
and moderated e-mail discussion lists which are complementary to our network.
 
INCREASE TRAFFIC AND ENHANCE WORLDWIDE BRAND RECOGNITION. We will continue to
expand the combination of online and offline advertising and promotional
campaigns to enhance the brand recognition of internet.com. We intend to promote
the internet.com brand as a leading source of online content focused solely on
the Internet industry. In addition, we will promote our branded Internet
services, such as Web Developer and The Electronic Commerce Guide, under the
internet.com network through online and offline advertising, strategic marketing
relationships, such as our arrangement with Penton Media, and other promotional
activities. Our marketing and branding campaigns are designed to
 
                                       36
<PAGE>
increase overall brand awareness. This increased brand awareness will help drive
additional traffic to our network and create additional advertising impressions,
which in turn will create additional advertising and e-commerce revenue
opportunities. As a result, this growth in user traffic should make our network
more valuable to advertisers and vendors. Our marketing and branding campaigns
will reinforce to users, advertisers and vendors that the internet.com brand
represents technical competence, comprehensiveness, timeliness and objectivity.
 
EXPAND REVENUE OPPORTUNITIES. For the three months ended March 31, 1999, 74% of
our revenues were derived from banner advertising. We believe that the increase
in the number of advertising impressions available for sale resulting from the
growth of subscribers to our e-mail newsletters and moderated e-mail discussion
lists will increase advertising revenues in the future. We are continuing to
develop additional revenue sources, including e-commerce agreements; content,
brand and software licensing; paid subscription services; seminars; opt-in
e-mail list rentals; and venture capital management. See "--Revenue
Opportunities."
 
INCREASE OUR INTERNATIONAL PRESENCE. The Internet is also rapidly growing
internationally and we intend to utilize our experience to continue to develop
and acquire Web sites, e-mail newsletters, online discussion forums and
moderated e-mail discussion lists with an international focus in order to expand
our global presence. We currently have internet.com country and regional Web
sites for Asia, Australia, Canada, Israel and the United Kingdom. These English
language editions are produced by our employees and freelance contributors in
the geographic areas they serve and provide daily Internet news from the country
or region. We also have licensed the internet.com brand and content for
non-English language editions. We are aggressively seeking opportunities in
other countries and regions to produce additional non-English language editions.
We intend to continue to develop and acquire English and non-English language
Internet media properties to increase our global presence.
 
REVENUE OPPORTUNITIES
 
ADVERTISING. For the three months ended March 31, 1999, 87% of our revenues were
derived from advertising, of which 91% of these advertising revenues were
generated from advertising on our Web sites and online discussion forums. With
the growth in subscribers to our e-mail newsletters and moderated e-mail
discussion lists, these media properties are also expected to contribute to
increased advertising revenues in the future.
 
E-COMMERCE AGREEMENTS. We have entered into a number of e-commerce agreements,
which generally include a fixed fee for advertising or revenue sharing of up to
50% of the sales made by the e-commerce vendor as a result of links from our
network, or in some cases both advertising and revenue sharing. E-commerce
agreements typically are a minimum of six months in duration. During the three
months ended March 31, 1999, 7% of our revenues were derived from e-commerce
agreements. Our current e-commerce vendors include:
 
<TABLE>
<S>        <C>                          <C>        <C>
- -          Biztravel.com, Inc.          -          FatBrain.com, Inc. (formerly Computer Literacy, Inc.)
 
- -          CareerBuilder, Inc.          -          Hewlett-Packard Company
 
- -          CompuBank, N.A.              -          Internet Wire Inc.
 
- -          Digital River, Inc.          -          Jintek, LLC
</TABLE>
 
LICENSING AGREEMENTS. We license our editorial content and brands to third
parties for fixed fees and royalties based on the licensee's revenues generated
by the licensed content. We also provide access to limited versions of our
editorial content to others at no charge, to promote our brands and generate
 
                                       37
<PAGE>
traffic. We have paid licensing arrangements with America Online, Inc.,
Ziff-Davis Inc., One Galaxy Solution, Inc., Upside Media Inc.'s UPSIDE MAGAZINE
and MBNA America Bank, N.A., among others. We also license our editorial content
and brands in exchange for promotional consideration to other Web sites,
including YAHOO.COM and SNAP.COM.
 
We license selected portions of our editorial content to print publishers. In
March 1999, we entered into an agreement with the Los Angeles Times Syndicate
International to license our editorial content to print periodicals. We also
license one-time rights to reprint individual articles, online or in print, to
third parties through licensing of reprints and copyright permission requests.
We have licensed our ISDEX, The Internet Stock Index, to the Kansas City Board
of Trade for the creation of futures and futures options contracts which are
expected to be traded on this exchange. We also offer our proprietary software
for license to third parties that offer services that are similar to, but do not
compete with, internet.com. For example, our NewsLinx software provides a highly
efficient and cost-effective means by which Internet content publishers can
abstract and aggregate news and information for any vertical subject area. For
the three months ended March 31, 1999, 2% of our revenues were derived from
licensing agreements.
 
PAID SUBSCRIPTION SERVICES. We currently publish three paid e-mail subscription
publications, Internet Stock Report's Hotwatch, Internet StockTracker and
SearchEngineWatch, which have a combined total of more than 9,000 paying
subscribers. We believe that our other content areas may attract audiences with
specialized interests that would pay subscription fees for unique proprietary
content and we will launch additional paid subscription services when
appropriate. In particular, we anticipate launching additional paid subscription
services in our Internet Stock, Internet Marketing and Web Developer Channels.
For the three months ended March 31, 1999, 4% of our revenues were derived from
paid subscription services.
 
SEMINARS. As a result of recent acquisitions, we plan to offer offline seminars
focused on several Internet-specific topics which are of interest to our
community of Internet users. We are able to efficiently promote these seminars
through our network. We anticipate generating revenues from attendee
registrations as well as from advertiser and vendor sponsorships. We have not
yet generated any revenues from seminars.
 
OPT-IN E-MAIL LIST RENTALS. Through a third-party agent, we currently offer for
rental our opt-in e-mail list names relating to 25 Internet-specific topics.
Members of our community of Internet users volunteer, or "opt in," to be
included on these lists to receive e-mail product offerings and information
relevant to their Internet interests. Subscribers to these opt-in e-mail lists
receive e-mail announcements of special offers relating to each topic
subscribed. For the three months ended March 31, 1999, 1% of our revenues were
derived from opt-in e-mail list rentals.
 
VENTURE FUND MANAGEMENT. We are the portfolio manager of internet.com Venture
Fund I LLC, a $5.0 million venture fund formed in April 1999, that will invest
in early-stage content-based Internet properties that are not competitive with
internet.com. We earn management fees for the day to day operation and general
management of the fund. We also earn 20% of the realized gains on investments
made by this fund. We committed to invest $600,000 in this fund at its
inception. The remaining $4.4 million was committed to by third party investors.
internet.com and all other investors contributed 15% of their total investments
to the fund at its inception. Remaining commitments will be called by the fund
as investments are actually made by the fund. We have not yet generated any
revenues from the management of this fund. See "Certain Transactions--Venture
Capital Fund."

We offer a broad range of content offerings and services to serve the needs of
our community of Internet users for content, community and commerce, as well as

SELECTED CASE STUDIES
 
INTERNETNEWS.COM. We created internetnews.com in November 1995. internetnews.com
publishes, on a real-time basis throughout each business day, approximately 25
original Internet news items which are produced by our staff of over 25 editors,
freelance contributors and analysts, and supplemented by content from Reuters
NewMedia Inc. and USA TODAY. The editorial philosophy of internetnews.com is to
provide members of our community of Internet users with current Internet
industry information. Monthly page views for internetnews.com increased 275%
from 746,000 in March 1998 to approximately 2.8 million in March 1999.
 
WEBDEVELOPER.COM. We launched WebDeveloper.com as a print publication with a
companion Web site in September 1995. In May 1997, Web Developer.com was
reconstituted as an exclusively online resource. WebDeveloper.com provides news,
software and book reviews, tutorials, and question and answer features for Web
developers. WebDeveloper.com appeals to professionals who are responsible for
building and maintaining Web sites. WebDeveloper.com also provides links to
other resources, many of which are within our network, containing reference
information on Web development topics. Monthly page views for WebDeveloper.com
increased 203% from 288,000 in March 1998 to 873,000 in March 1999.
 
THE LIST--"THE DEFINITIVE ISP BUYER'S GUIDE". We acquired The List in August
1995 and have continued to enhance its content offerings and services, making
The List a leading directory of ISPs on the Internet. The List currently
provides access to information detailing the service offerings and rates of
6,700 ISPs in more than 200 countries worldwide. The List is based on a
contributory system that allows ISPs to enter information about rates and
services offered. The List offers ISPs a targeted method of acquiring
subscribers through sponsoring or providing advertising on specific pages
corresponding to area codes in which they provide service, allowing them to
effectively reach potential customers. In April 1999, we launched a program of
selling enhanced listings and sponsorships that allows ISPs to add their logos
to The List and more effectively target new customers. Monthly page views for
The List increased 69% from approximately 1.3 million in March 1998 to
approximately 2.2 million in March 1999.
 
SEARCHENGINEWATCH. We acquired SearchEngineWatch in November 1997.
SearchEngineWatch serves two audiences: marketers who want to have their
companies' Web sites listed prominently in search engines and sophisticated
Internet users who want to make informed selections when choosing a search
engine to use. In addition to advertising and sponsorship revenue,
SearchEngineWatch offers a paid subscription newsletter on its Web site. Since
acquiring and integrating SearchEngineWatch into our network in November 1997,
we have rapidly increased the number of paid subscribers while at the same time
increasing the annual subscription rate for this service from $25 to $44.
Monthly page views for SearchEngineWatch increased 109% from 573,000 in March
1998 to approximately 1.2 million in March 1999.
 
EDITORIAL
 
We maintain editorial offices in Westport, Connecticut; New York, New York;
Lexington, Kentucky; and Ann Arbor, Michigan. In addition, editorial personnel
work from home offices throughout the United States and in Hong Kong. Freelance
contributors and analysts are also located both domestically and in 13 countries
worldwide.
 
Our editorial team, comprised of 33 employees and over 50 freelance contributors
as of April 30, 1999, creates considerable proprietary content each month. For
example, in April 1999, our editorial team:
 
                                       44
<PAGE>
      -      authored more than 700 news articles published in InternetNews;
 
      -      authored more than 50 technical tutorials;
 
      -      authored more than 100 market analysis reports;
 
      -      reviewed more than 140 products and books;
 
      -      created more than 450 editions of 43 separate e-mail newsletters;
 
      -      moderated over 50 e-mail discussion lists and over 50 online
             discussion forums;
 
      -      catalogued and evaluated more than 1,300 software programs; and
 
      -      maintained more than 10,000 directory listings of Internet-related
             products, services and companies.
 
In addition, our editorial staff also maintains an online dictionary,
WWW.WEBOPEDIA.COM, of 7,500 Internet and technology terms, writes question and
answer columns and creates directories of scripts for major Internet
technologies. We also have an exclusive agreement to serve as the Internet
publisher of Penton Media's INTERNET WORLD, BOARDWATCH and DIRECTORY OF INTERNET
SERVICE PROVIDERS print publications, as well as information about Penton
Media's Internet World and ISPCON trade shows. See "Certain
Transactions--Services Agreement."
 
MARKETING AND SALES
 
MARKETING. We employ a combination of online and offline advertising and
promotional campaigns to promote our content offerings and services to our
community of Internet users, advertisers and vendors. User advertising includes
cross-promotion on our network, advertising in trade publications and at trade
shows and promotional links from Web sites that attract demographically similar
audiences. We believe that this strategy maintains the high quality and unique
focus of our community of Internet users. We have participated in various
Internet industry events, including Internet World and ISPCON trade shows. We
have also used print advertising, which has appeared in INTERNET WORLD,
BOARDWATCH, UPSIDE, INTERNET WEEK, DATA COMMUNICATIONS, TELE.COM, SILICON ALLEY
REPORTER and ADWEEK, among other publications.
 
Our marketing efforts are directed largely at acquiring advertising clients and
commerce agreements. We principally use offline and online advertising, direct
mail and event sponsorships for customer acquisition. ADVERTISING AGE, ADWEEK,
MARKETING COMPUTERS, CLICKZ, CHANNELSEVEN.COM and the ONLINE ADVERTISING
DISCUSSION LIST are among the venues used to deliver our promotional messages.
In addition, we have a strategic agreement with Penton Media, a significant
investor in internet.com, which provides for an exchange of services to be
provided by each party. This agreement expires on November 23, 2001 and is
automatically renewable for subsequent three year terms unless terminated by
either party.
 
Services provided by Penton Media to us under this agreement include the
following:
 
      -      one full-page advertisement at no charge in each issue of INTERNET
             WORLD newspaper and BOARDWATCH magazine;
 
      -      exhibit and sales office space at no charge for each U.S. Internet
             World and ISPCON trade show; and
 
      -      prominent listing as a sponsor in all promotional materials and for
             appropriate conference tracks, as well as prominent hanging media
             banners for Internet World and ISPCON trade shows.
 
                                       45
<PAGE>
Services we provide to Penton Media under this agreement include the following:
 
      -      Web site archives of INTERNET WORLD and BOARDWATCH print
             publications and information about Internet World and ISPCON trade
             shows and conferences; and
 
      -      a minimum of 2.3 million advertising impressions each month on our
             network.
 
ADVERTISING SALES. We believe that we have been able to obtain revenue from
advertising on our Web sites and online discussion forums because we enable
clients to efficiently and effectively reach targeted segments of the Internet
community. Based on a survey we commissioned which was conducted from August
1998 through February 1999, 83% of our community of Internet users report that
they either make or influence purchasing decisions. We believe that targeting
this influential audience allows us to sell advertising space at rates that are
higher than the average rates charged by online services aimed at more general
audiences. Based upon publicly available banner advertisement rate cards, we
believe that our actual rates are approximately 1.4 to 4.0 times higher than the
published rates of Go2Net, Inc., Netscape Communications Corp., Yahoo! Inc. and
Infoseek Corporation as of April 1999, which we believe to be a representative
group of Internet-based services aimed at more general audiences.
 
We also offer advertisers the opportunity to advertise on our e-mail newsletters
and moderated e-mail discussion lists. In April 1999, we distributed 8.1 million
copies of our e-mail newsletters to over 700,000 subscribers. We also
distributed 31.2 million messages to more than 51,000 moderated e-mail
discussion list subscribers.
 
Our sales force is organized by geographic regions as follows: New England, New
York Metro, Mid-Atlantic/Southeast, Midwest, West, Canada, Europe and Israel.
 
Over 450 advertisers have placed advertisements on our network. For the six
months ended March 31, 1999, International Business Machines Corporation
accounted for 17% of our revenues, and our top 20 advertisers together accounted
for 50% of our revenues during the same period. The following were our top 20
advertisers during the six months ended March 31, 1999:
 
       Allaire Corporation
       Apple Computer, Inc.
       Ariel Corporation
       Biztravel.com, Inc.
       Dell Computer Corporation
       Digital River, Inc.
       Earthlink Networks, Inc.
       GoTo.com, Inc.
       Hewlett-Packard Company
       Inktomi Corporation

       Macromedia Inc.
       Microsoft Corporation
       Northern Telecom Limited
       Oracle Corporation
       OrderTrust LLC
       Surfree.com Inc.
       Transarc Corporation
       Ubid, Inc.
 
E-COMMERCE SALES, LICENSING AND BUSINESS DEVELOPMENT. We offer e-commerce,
licensing and other business development arrangements to maximize the potential
of our proprietary content and community of Internet users. We identify
potential e-commerce vendors, licensees and other potential business development
opportunities and generally enter into contracts of six to 12 months' duration.
E-commerce agreements generally include a fixed fee for advertising as well as
revenue sharing of up to 50% of the sales made by the e-commerce vendor as a
result of links from our network. These activities are conducted by a staff of
three employees separate from our advertising sales force.
 
Licensing arrangements allow third parties to reproduce our editorial content
and brands either for print or online use. We are typically paid per-use in the
case of book and print rights, including reprints of articles published on our
network, and monthly in cases where our editorial content is published in
 
                                       46
<PAGE>
electronic form. We also offer our proprietary software for license to third
parties that offer services that are similar to, but do not compete with,
internet.com.
 
COMPETITION
 
We believe we compete on the basis of our brand recognition and our proprietary
content offerings and services focused solely on the Internet industry. We
believe that we are differentiated relative to our competitors due to our
vertical focus of providing content, community and commerce to Internet industry
and Internet technology professionals, Web developers and experienced Internet
users.
 
The market for Internet-based services is relatively new, intensely competitive
and rapidly changing. Since the advent of commercial services on the Internet,
the number of online services competing for users' attention and spending has
proliferated. We expect that competition will continue to intensify. We compete
with other companies which direct a portion of their overall Web content at the
Internet professional community, such as Ziff-Davis Inc.'s ZDNet, C/NET, CMP
Media Inc., EarthWeb Inc. and Wired Digital Inc. We also compete for circulation
and advertising impressions with general interest portal and destination Web
sites as well as traditional media.
 
Many of our current and potential competitors have longer operating histories,
larger customer bases, greater brand recognition and significantly greater
financial, marketing and other resources than we have. These competitors may be
able to respond more quickly to new or emerging technologies and changes in
customer requirements and to devote greater resources to the development,
promotion and sale of their products and services than we can. The number of
companies competing for the attention and spending of our community of Internet
users has increased and we expect it to continue to increase. See "--Industry
Overview" and "Risk Factors--We face intense competition."
 
TECHNOLOGY AND OPERATIONS
 
We have developed an expandable operations infrastructure using open standard
hardware and software systems. We make our Web sites, e-mail newsletters, online
discussion forums and moderated e-mail discussion lists available using multiple
Sun Microsystems, Inc. and Wintel-based servers that run on Sun Solaris and
Microsoft NT operating systems. We license software from the following parties,
among others: Web and e-mail servers from Netscape; Web and database servers
from Microsoft Corporation; an advertising management system from NetGravity,
Inc.; a content management system from Vignette Corporation; a log and traffic
analysis system from net.Genesis Corp.; a streaming media server from
RealNetworks, Inc.; a spidering, content indexing, personalization and
categorization system from Autonomy, Inc.; and a firewall from Network
Associates Inc.
 
We maintain a data center with redundant production and staging servers. In the
event that all of the production servers fail, the staging servers are capable
of supporting our services. Our redundant Internet circuits are diversely routed
to different points within our providers' networks, so that interruptions will
be minimized if a failure in one network segment occurs. All of our servers are
powered by uninterruptible power supplies. In addition, all of our production
systems are copied to backup tapes each night and stored at an off-site storage
facility each business day. In the event of a disaster at the production
facility, arrangements are in place to resume production at an off-site center
maintained by International Business Machines. We maintain a quality assurance
process to constantly monitor our servers, processes and network connectivity.
We have implemented these redundancies and backup systems in order to minimize
the risk associated with damage from fire, power loss, telecommunications
failure, break-ins, computer viruses and other events beyond our control. See
"Risk Factors--Our systems are subject to damage from natural disasters,
telecommunication failures, electronic break-ins and similar problems."

INTELLECTUAL PROPERTY
 
We regard our content, logos, brands and software as proprietary and attempt to
protect them by relying on trademark, copyright, trade secret and other laws and
restrictions. We currently have no patents or patents pending and do not
anticipate that patents will become a significant part of our intellectual
property in the foreseeable future. We pursue the registration of our trademarks
and service marks in the United States and internationally, and have applied for
registration in the United States and numerous other countries for a number of
our trademarks and service marks. We also pursue copyright registration of our
content in the United States. We might not be able to obtain effective
trademark, copyright and trade secret protection in every country in which we
distribute our services or make them available through the Internet, and it is
difficult for us to police unauthorized use of our proprietary information. We
seek protection of our content, logos, brands and software relating to our Web
sites, e-mail newsletters, online discussion forums and moderated e-mail
discussion lists.
 
We have applied for registration of our trademarks and service marks in the
United States and in over 60 other countries. We have encountered obstacles to
registration of some marks in several of these countries.
 
We are opposing an application by IDG to register the trademark "internet.com"
in the United States Patent and Trademark Office. IDG has filed an intent-to-use
application that predates our applications to register this trademark for
substantially similar goods and services. We have, however, been using this
trademark for several years, and we believe that our actual use predates IDG's
intent-to-use application. The Patent and Trademark Office must decide whether
our actual use of the internet.com trademark predates the IDG intent-to-use
application date and whether such use amounts to actual trademark use. We
believe that we will be successful in opposing IDG's intent-to-use application
on these grounds, but there can be no guarantee of this outcome. If we are
unsuccessful in opposing IDG's intent-to-use application, IDG could limit the
scope of our use of the internet.com trademark, could use the internet.com
trademark simultaneously with our use or could charge a fee for such use,
although we would have the option of pursuing our rights in federal court in
that event.
 
Legal standards relating to the validity, enforceability and scope of protection
of proprietary rights in Internet-related businesses are uncertain and still
evolving. As a result, we cannot assure the future viability or value of our
proprietary rights. We might not have taken adequate steps to prevent the
misappropriation or infringement of our intellectual property. Any such
infringement or misappropriation, should it occur, might harm our business,
results of operations and financial condition. In addition, we may have to file
lawsuits in the future to perfect or enforce our intellectual property rights,
to protect our trade secrets or to determine the validity and scope of the
proprietary rights of others. These lawsuits could result in substantial costs
and divert our resources and the attention of our management. As a result, our
business, results of operations and financial condition would suffer.
 
Our business activities may infringe upon the proprietary rights of others, and
other parties might assert infringement claims against us. From time to time, we
have been, and expect to continue to be, subject to claims in the ordinary
course of our business including claims of alleged infringement of the
trademarks, service marks and other intellectual property rights of third
parties. If similar claims are made against us in the future, those claims and
any resultant litigation might subject us to liability for damages, result in
invalidation of our proprietary rights and, even if not meritorious, could be
time consuming and expensive to defend and could result in the diversion of our
resources and the attention of our management. As a result, our business,
results of operations and financial condition would suffer.
 
                                       48
<PAGE>
We generally obtain our content and some of our technology from our employees or
pursuant to work-for-hire arrangements. We also license technology and content
from third parties. In such license arrangements, we generally obtain
representations as to origin and ownership of such content and technology and
the licensors have generally agreed to defend, indemnify and hold us harmless
from any third party claims that such technology or content violates the rights
of another. We cannot be sure that these third party technology and content
protections will be effective or sufficient or that we will be able to maintain
such content or technology on commercially reasonable terms. As a result, our
business, results of operations and financial condition would suffer.
 
We have licensed in the past, and expect to license in the future, proprietary
rights, such as trademarks or copyrighted material, to third parties. While we
attempt to ensure that the quality of our brands and content are maintained by
such licensees, we cannot be sure that such licensees will not take actions that
might decrease the value of our brands, proprietary rights or reputation, which
would harm our business, prospects, financial condition and results of
operations.
 
DOMAIN NAMES
 
We own the Internet domain name "internet.com," as well as numerous other domain
names both in the United States and internationally. Domain names generally are
regulated by Internet regulatory bodies. The regulation of domain names in the
United States and in foreign countries is subject to change. Regulatory bodies
could establish additional top-level domains, appoint additional domain name
registrars or modify the requirements for holding domain names. As a result, we
might not acquire or maintain the "internet.com" or comparable domain name in
all the countries in which we conduct business.
 
The relationship between regulations governing domain names and laws protecting
trademarks and similar proprietary rights is unclear and still evolving.
Therefore, we might be unable to prevent third parties from acquiring domain
names that infringe or otherwise decrease the value of our trademarks and other
proprietary rights. See "Risk Factors--Regulation could reduce the value of our
domain names."

1999 STOCK INCENTIVE PLAN
 
On April 15, 1999, we adopted the internet.com Corporation 1999 Stock Incentive
Plan. We will issue options to purchase 510,500 shares of our common stock to
our directors, officers and employees concurrently with the closing of this
offering. The exercise price of options granted under the 1999 Stock Incentive
Plan will not be less than the fair market value of the shares of our common
stock on the date of grant. The purpose of the plan is to provide stock-based
incentive compensation to these individuals to further align their interests
with the interests of our stockholders. We have reserved 2,000,000 shares of
common stock for issuance pursuant to the exercise or vesting of awards under
the plan.
 
The plan allows for the discretionary grant of restricted stock, non-qualified
stock options, incentive stock options as defined in Section 422 of the Internal
Revenue Code of 1986, as amended, and other stock-based awards. In addition, the
plan provides for the automatic grant of non-qualified stock options to our
directors who are not also employees or officers of internet.com. Only
directors, key employees and consultants may receive discretionary awards under
the plan.
 
The plan will be administered by the compensation committee of our board of
directors. The compensation committee will make the determination with respect
to the discretionary awards under the plan, including which eligible individuals
are to receive awards under the plan and the specific terms, vesting conditions,
if any, and number of shares of stock to which each award relates.
 
The compensation committee may grant awards with different terms and conditions.
The compensation committee can also accelerate the vesting of outstanding awards
and can reprice any option at any
 
                                       54

time. At the time options are granted, the compensation committee will set the
price at which options can be exercised to purchase shares of common stock.
 
Option holders will not have any rights as stockholders until and to the extent
they have exercised their options. The exercise price for options may either be
paid in cash or check or, at the discretion of the compensation committee, by
tendering shares having a value equal to the exercise price. The number of
shares of common stock covered by awards will be adjusted in the event of any
stock split, merger, recapitalization or similar corporate event.
 
The board of directors may terminate or amend the stock plan at any time, except
that the board may not, without the approval of our stockholders, increase the
maximum number of shares for which options may be granted under the stock plan
or expand the class of individuals eligible to participate in the plan.
 
Immediately after this offering, we intend to file a registration statement
under the Securities Act covering the 2,000,000 shares of common stock reserved
for issuance under the plan. See "Shares Eligible for Future Sale--Stock
Options."

INDEMNIFICATION OF DIRECTORS AND EXECUTIVE OFFICERS AND LIMITATION OF LIABILITY
 
Our Amended and Restated Certificate of Incorporation will include a provision
that eliminates the personal liability of our directors for monetary damages for
breach of fiduciary duty as a director, except for liability:
 
      -      for any breach of the director's duty of loyalty to internet.com or
             its stockholders;
 
      -      for acts or omissions not in good faith or that involve intentional
             misconduct or a knowing violation of law;
 
      -      under Section 174 of the Delaware General Corporation Law regarding
             unlawful dividends and stock purchases; and
 
      -      for any transaction from which the director derived an improper
             personal benefit.
 
Our Amended and Restated Certificate of Incorporation will also provide that:
 
      -      we must indemnify our directors, officers, other employees and
             agents to the fullest extent permitted by the Delaware General
             Corporation Law, subject to certain very limited exceptions; and
 
      -      we must pay expenses of our directors, and may pay expenses of our
             officers, other employees, agents or trustees, incurred in
             connection with a legal proceeding before the final disposition of
             such proceeding.
 
These provisions are permitted under the Delaware General Corporation Law. In
addition, our Bylaws provide that we must indemnify our directors and officers
to the fullest extent permitted by the Delaware General Corporation Law.
 
Prior to the completion of this offering, we intend to enter into indemnity
agreements with each of our directors and executive officers to give them
additional contractual assurances regarding the scope of the indemnification
described above and to provide additional procedural protections. In addition,
we intend to obtain directors' and officers' insurance providing indemnification
for our directors, officers and management employees for liabilities arising as
a result of their employment at internet.com. We believe that these
indemnification provisions and agreements are necessary to attract and retain
qualified directors and officers.
 
The limitation of liability and indemnification provisions in our Amended and
Restated Certificate of Incorporation and Bylaws may discourage stockholders
form bringing a lawsuit against directors for breach of their fiduciary duty.
They may also reduce the likelihood of derivative litigation against directors
and officers, even though such an action, if successful, might otherwise benefit
us and our stockholders. Furthermore, a stockholder's investment may be
adversely affected to the extent we pay the costs of settlement and damage
awards against directors and officers pursuant to these indemnification
provisions.
 
At present, there is no pending litigation or proceeding involving any of our
directors, officers or employees regarding which indemnification is sought, nor
are we aware of any threatened litigation that may result in claims for
indemnification.

                              CERTAIN TRANSACTIONS
 
FORMATION TRANSACTIONS
 
internet.com LLC was formed as part of the acquisition of Mecklermedia
Corporation by Internet World Media, a wholly-owned subsidiary of Penton Media
(a publicly-owned corporation). During the negotiation of this acquisition,
Penton Media indicated that it did not wish to retain all of iWorld Corporation,
Mecklermedia's Internet business, because it believed that the Internet business
was inconsistent with its planned strategic direction. However, Penton Media
indicated that it wanted Internet World Media to maintain a minority interest in
the Internet business due to its belief that the Internet business had the
potential to become profitable in the future. As a result, Alan M. Meckler,
Mecklermedia's Chairman and Chief Executive Officer, agreed to purchase an 80.1%
interest in the Internet business from Internet World Media for a total of $18.0
million in cash immediately following the acquisition of Mecklermedia by
Internet World Media. On November 24, 1998, Mecklermedia, was acquired by
Internet World Media in an all-cash tender offer. Following its purchase of
Mecklermedia, Internet World Media caused iWorld Corporation to be merged into
internet.com LLC, a newly-formed Delaware limited liability company. Internet
World Media then sold 80.1% of its membership interest in internet.com to Alan
M. Meckler (including four trusts for the benefit of his children) for a total
of $18.0 million in cash. Internet World Media retained a 19.9% interest in
internet.com LLC and a warrant to acquire up to an additional 128 membership
units in internet.com LLC (representing 2,075,634 shares of our common stock)
for up to $3.0 million. The following chart summarizes the organizational events
from the acquisition of Mecklermedia by Penton Media to the closing of this
offering:

In March 1999, internet.com sold additional membership units to Internet World
Media and to several additional investors, some of whom are employees, officers
or directors of internet.com. In addition, in March 1999, we granted 49.33, or
4%, of internet.com's total membership units at the time (assuming full
dilution, including the exercise of the Internet World Media warrant) to 15 of
our employees. The following table summarizes the number of units sold in March
1999, the number of shares of internet.com Corporation common stock into which
those units will be converted immediately prior to the consummation of this
offering, and the resulting price per share:

internet.com LLC were sold and granted after November 24, 1998, and a Second

WARRANT AGREEMENT. On November 24, 1998, we issued a warrant to Internet World
Media to acquire up to 128 additional membership units in internet.com LLC for
up to $3.0 million. Upon the conversion of internet.com LLC into a corporation,
this warrant will entitle Internet World Media to purchase up to 2,075,634
shares of our common stock at an exercise price of approximately $1.45 per
share. Internet World Media has informed us that it intends to exercise this
warrant prior to the closing of this offering of common stock. As a result of
such exercise, following this offering, Internet World Media will hold 5,483,383
shares of our common stock, or approximately 23.4% of the total shares of our
common stock which will be outstanding immediately following this offering
(assuming the underwriters do not exercise their over-allotment option). If
Internet World Media does not exercise its warrant prior to the consummation of
this offering, the warrant will expire upon consummation of this offering.

                          DESCRIPTION OF CAPITAL STOCK
 
Upon the closing of this offering, we will have authorized capital stock
consisting of 75,000,000 shares of common stock, $0.01 par value per share, and
4,000,000 shares of preferred stock, $0.01 par value per share. As of March 31,
1999, assuming the conversion of our business form into a corporation, the
simultaneous conversion of limited liability company membership units into
shares of common stock and the exercise by Internet World Media of a warrant to
purchase up to 2,075,634 shares of common stock, there were outstanding
20,000,000 shares of common stock, each with a par value of $0.01, held of
record by 25 stockholders.
 
The following description of internet.com's Amended and Restated Certificate of
Incorporation, Bylaws and the Registration Rights Agreement is only a summary,
and does not purport to be complete. For a full understanding of these documents
and the terms of our capital stock, you should read the original documents,
which are included as exhibits to the registration statement of which this
prospectus forms a part.
 
COMMON STOCK
 
Subject to preferences that may be applicable to any preferred stock outstanding
at the time, the holders of outstanding shares of common stock are entitled to
receive dividends out of assets legally available therefor at such times and in
such amounts as the board from time to time may determine. Holders of common
stock are entitled to one vote for each share held on all matters submitted to a
vote of shareholders. Cumulative voting for the election of directors is not
authorized by internet.com's Amended and Restated Certificate of Incorporation,
which means that the holders of a majority of the shares voted can elect all of
the directors then standing for election. The common stock is not entitled to
preemptive rights and is not subject to conversion or redemption. Upon
liquidation, dissolution or winding up of internet.com, the assets legally
available for distribution to stockholders are distributable ratably among the
holders of the common stock after payment of liquidation preferences, if any, on
any outstanding preferred stock and payment of other claims of creditors. Each
outstanding share of common stock is, and all shares of common stock to be
outstanding upon completion of this offering will upon payment therefor be, duly
and validly issued, fully paid and nonassessable.
 
PREFERRED STOCK
 
The board is authorized, subject to any limitations prescribed by the Delaware
General Corporation Law, to issue preferred stock in one or more series. The
board can fix the rights, preferences and privileges of the shares of each
series and any qualifications, limitations or restrictions thereon.
 
The board may authorize the issuance of preferred stock with voting or
conversion rights that could adversely affect the voting power or other rights
of the holders of common stock. The issuance of preferred stock, while providing
flexibility in connection with possible acquisitions and other corporate
purposes, could, among other things, have the effect of delaying, deferring or
preventing a change in control of internet.com. We have no current plans to
issue any shares of preferred stock. See "Risk Factors--Our charter documents
and the Delaware General Corporation Law may inhibit a takeover."
 
WARRANTS
 
On November 24, 1998, we issued a warrant to Internet World Media which will
entitle Internet World Media to acquire additional shares of common stock prior
to the closing of this offering. See "Certain Transactions--Formation
Transactions--Warrant Agreement."
 
                                       61

REGISTRATION RIGHTS
 
We entered into a Registration Rights Agreement with Internet World Media at the
closing of the acquisition of Mecklermedia by Internet World Media. Internet
World Media has piggyback registration rights if we register any of our equity
securities under the Securities Act of 1933, as amended, other than the common
stock offered by this prospectus, securities relating to employee benefits
plans, securities registered pursuant to Rule 145 of the Securities Act of 1933,
as amended, in connection with reclassifications, mergers, acquisitions and
asset transfers and registrations which do not permit secondary sales. If we
register additional equity securities in the future, Internet World Media will
have the right to have all or a part of its internet.com common stock included
in the registration, including any shares of common stock acquired by Internet
World Media by the exercise of its warrant. However, the managing underwriter,
if any, of any such offering has the right to limit the number of securities
that Internet World Media may include in such registration if the managing
underwriter determines that marketing factors require such a limitation.
Internet World Media is entitled to unlimited piggyback registrations.
 
We would bear all registration expenses incurred in connection with these
registrations. Internet World Media would pay all underwriting discounts and
selling commissions applicable to the sale of its securities.
 
DELAWARE ANTI-TAKEOVER LAW AND CERTAIN CHARTER AND BYLAW PROVISIONS
 
EFFECT OF DELAWARE ANTI-TAKEOVER STATUTE. We are subject to Section 203 of the
Delaware General Corporation Law, which, subject to certain exceptions,
prohibits a publicly held Delaware corporation from engaging in any "business
combination" with any "interested stockholder" for a period of three years
following the date that such stockholder became an interested stockholder,
unless:
 
      -      prior to such date, the board of directors of the corporation
             approved either the business combination or the transaction that
             resulted in the stockholder becoming an interested stockholder;
 
      -      upon consummation of the transaction that resulted in the
             stockholder becoming an interest stockholder, the interested
             stockholder owned at least 85% of the voting stock of the
             corporation outstanding at the time the transaction commenced; and
 
      -      on or subsequent to such date, the business combination is approved
             by the board of directors and authorized at an annual or special
             meeting of stockholders, and not by written consent, by the
             affirmative vote of at least 66 2/3% of the outstanding voting
             stock that is not owned by the interested stockholder.
 
Section 203 defines "business combination" to include:
 
      -      any merger or consolidation involving the corporation and the
             interested stockholder;
 
      -      any sale, transfer, pledge or other disposition of 10% or more of
             the assets of the corporation involving the interested stockholder;
 
      -      subject to certain exceptions, any transaction that results in the
             issuance or transfer by the corporation of any stock of the
             corporation to the interested stockholder;
 
      -      any transaction involving the corporation that has the effect of
             increasing the proportionate share of the stock of any class or
             series of the corporation beneficially owned by the interested
             stockholder; and
 
                                       62
<PAGE>
      -      the receipt by the "interested stockholder" of the benefit of any
             loans, advances, guarantees, pledges or other financial benefits
             provided by or through the corporation.
 
In general, Section 203 defines an interested stockholder as an entity or person
beneficially owning 15% or more of the outstanding voting stock of the
corporation and any entity or person affiliated with or controlling or
controlled by such entity or person.
 
This statute could prohibit or delay mergers or other takeover or
change-in-control attempts with respect to internet.com and, accordingly, may
discourage attempts to acquire us.
 
Our Bylaws provide that any action required or permitted to be taken by our
stockholders at an annual meeting or special meeting may only be taken if it is
properly brought before such meeting. The Amended and Restated Certificate of
Incorporation and the Bylaws provide that special meetings of the stockholders
may only be called by the Chairman of the board, the Chief Executive Officer,
the board or by the President, who will call a meeting at the request of any
stockholder or stockholders holding together at least a majority of the
outstanding voting stock. Such provisions may have the effect of delaying or
preventing a change-in-control.
 
The board is authorized, subject to any limitations prescribed by the Delaware
General Corporation Law, to issue preferred stock in one or more series. The
board can fix the rights, preferences and privileges of the shares of each
series and any qualifications, limitations or restrictions thereon. The board
may authorize the issuance of preferred stock with voting or conversion rights
that could adversely affect the voting power or other rights of the holders of
common stock. The issuance of preferred stock, while providing flexibility in
connection with possible acquisitions and other corporate purposes, could, among
other things, have the effect of delaying, deferring or preventing a change in
control of internet.com.

Amended and Restated Certificate of Incorporation and our Bylaws limit liability
of directors to the fullest extent permitted by the Delaware General Corporation

of Rule 144 and 701, the restricted securities will be available for sale in the

of the registration statement of which this prospectus forms a part, subject to
the volume limitations and other conditions of Rule 144.
 
LOCK-UP AGREEMENTS. Our officers, directors and all of our remaining
stockholders have signed lock-up agreements under which they agreed not to
transfer or dispose of, directly or indirectly, any shares of common stock or
any securities convertible into or exercisable or exchangeable for shares of

our common stock for at least one year would be entitled to sell within any
three-month period a number of shares that does not exceed the greater of:
 
      -      1% of the number of shares of common stock then outstanding, which
             will equal 234,000 shares immediately after this offering; or
 
      -      the average weekly trading volume of the common stock on the Nasdaq
             National Market during the four calendar weeks preceding the filing
             of a notice on Form 144 with respect to such sale.
 
Sales under Rule 144 are also subject to certain manner of sale provisions and
notice requirements and to the availability of current public information about
us.
 
RULE 144(K). Under Rule 144(k), a person who is not deemed to have been one of
our affiliates at any time during the 90 days preceding a sale, and who has

including the holding period of any prior owner other than an affiliate, is
entitled to sell such shares without complying with the manner of sale, public
information, volume limitation or notice provisions of Rule 144.

5,483,383 shares of our common stock, or its transferees, will be entitled to
rights with respect to the registration of such shares under the Securities Act
of 1933, as amended, if we register additional equity securities under the
Securities Act. See "Description of Capital Stock--Registration Rights." After
such a registration, any shares registered would become freely tradable without
restriction under the Securities Act of 1933, as amended. Internet World Media
would then not have any obligation or other restrictions on resale with respect
to our common stock, other than restrictions imposed by lock-up agreements
described above and applicable securities laws.
 
STOCK OPTIONS. Immediately after this offering, we intend to file a registration
statement under the Securities Act of 1933, as amended, covering the 2,000,000

internet.com estimates that the total expenses of this offering, excluding
underwriting discounts and commissions, will be approximately $        .
 
The underwriters propose to offer the shares of common stock directly to the
public at the initial public offering price set forth on the cover page of this
prospectus and to certain dealers at that price less a concession not in excess
of $        per share. The underwriters may allow and these dealers may reallow
a concession not in excess of $        per share to certain other dealers. After
the initial public offering of the shares has been completed, the offering price
and other selling terms may be changed by the representatives of the
underwriters. The representatives have informed internet.com that the
underwriters do not intend to confirm discretionary sales in excess of 5% of the
shares of common stock offered by this prospectus.
 
An electronic prospectus is available on the Web site maintained by DLJDIRECT
Inc., a selected dealer, which is facilitating the Internet distribution of the
shares of common stock being offered by this prospectus.
 
Internet World Media, a wholly-owned subsidiary of Penton Media, has granted to
the underwriters an option to purchase up to an additional 510,000 shares of our
common stock, at the same price to the public, and with the same underwriting
discount, as set forth in the table above. The underwriters may exercise this
option any time during the 30-day period after the date of this prospectus, but
only to cover over-allotments, if any. To the extent the underwriters exercise
the option, each underwriter will become obligated, subject to certain
conditions, to purchase approximately the same percentage of the additional
shares as it was obligated to purchase under the purchase agreement.

We and the selling stockholder have agreed to indemnify the underwriters against
certain liabilities, including civil liabilities under the Securities Act of
1933, as amended, or to contribute to payments that the underwriters may be
required to make in respect of those liabilities.
 
We and each of our directors, executive officers and stockholders have agreed to
certain restrictions on our ability to sell additional shares of our common
stock for a period of 180 days after the date of this prospectus. We have agreed
not to directly or indirectly offer for sale, sell, contract to sell, grant any
option for the sale of, or otherwise issue or dispose of, any shares of common
stock, options or warrants to acquire shares of common stock, or any related
security or instrument, without the prior written consent of the
representatives. The agreements provide exceptions for (1) sales to the
underwriters pursuant to the purchase agreement, (2) our sales in connection
with the exercise of options granted and the granting of options to purchase
shares under the existing stock option plan and (3) other exceptions specified
in the purchase agreement and lock-up agreements.
 
Of the 3,400,000 shares of common stock offered by us, 170,000 shares will be
reserved for sale to persons designated by us. Total shares reserved for sale to
persons designated by us will not exceed 5% of the total shares offered. Shares
not sold to these persons will be reoffered immediately by the underwriters to
the public at the initial public offering price.
 
Prior to the offering, there has been no established trading market for the
common stock. The initial public offering price for the shares of common stock
offered by this prospectus was negotiated by us and the underwriters. The
factors considered in determining the initial public offering price include the
history of and the prospects for the industry in which we compete, our past and
present operations, our historical results of operations, our prospects for
future earnings, the recent market prices of securities of generally comparable
companies and the general condition of the securities markets at the time of the
offering and other relevant factors. There can be no assurance that the initial
public offering price of the common stock will correspond to the price at which
the common stock will trade in the public market subsequent to this offering or
that an active public market for the common stock will develop and continue
after this offering.
 
PRICING OF THIS OFFERING
 
Prior to this offering, there has been no public market for our common stock.
Consequently, the initial public offering price for our common stock was
determined by negotiation among internet.com and the representatives of the
underwriters. Among the factors considered in determining the public offering
price were:
 
      -      prevailing market conditions;
 
      -      our results of operations in recent periods;
 
      -      the present stage of our development;
 
      -      the market capitalizations and stages of development of other
             companies which we and the representatives of the underwriters
             believe to be comparable to internet.com; and
 
      -      estimates of our business potential.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors of internet.com LLC:
 
We have audited the accompanying balance sheet of internet.com LLC (a Delaware
limited liability company) as of December 31, 1998, and the related statements
of operations, changes in members' capital and cash flows for the period from
inception (November 24, 1998) through December 31, 1998. These financial
statements are the responsibility of the company's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
 
We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of internet.com LLC as of December
31, 1998, and the results of its operations and its cash flows for the period
from inception (November 24, 1998) through December 31, 1998, in conformity with
generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
FOR THE PERIOD FROM INCEPTION (NOVEMBER 24, 1998) THROUGH DECEMBER 31, 1998 AND

1. ORGANIZATION AND NATURE OF BUSINESS
 
Immediately prior to the closing of this offering, internet.com LLC will convert
its business form to a corporation. This reorganization will be effected by
merging internet.com LLC into a newly-formed Delaware corporation called
internet.com Corporation. Each member of internet.com LLC will receive shares of
internet.com Corporation common stock in exchange for his or her membership
units at a rate of 16,215.891 shares per membership unit. internet.com
Corporation currently is a shell entity and will remain as such until the
conversion of internet.com LLC into a corporation. internet.com Corporation
currently has no assets, liabilities, revenues nor expenses.
 
HISTORY. internet.com LLC was formed as part of the acquisition of Mecklermedia
Corporation by Internet World Media, a wholly-owned subsidiary of Penton Media
(a publicly-owned corporation). During the negotiation of this acquisition,
Penton Media indicated that it did not wish to retain all of iWorld Corporation,
Mecklermedia's Internet business, because it believed that the Internet business
was inconsistent with its strategic direction. However, Penton Media indicated
that it wanted Internet World Media to maintain a minority interest in the
Internet business due to its belief that the Internet business had the potential
to become profitable in the future. As a result, Alan M. Meckler, Mecklermedia's
Chairman and Chief Executive Officer, agreed to purchase an 80.1% interest in
the Internet business from Internet World Media for a total of $18.0 million in
cash immediately following the acquisition of Mecklermedia by Internet World
Media which imputed a purchase price of $22.5 million. On November 24, 1998,
Mecklermedia was acquired by Internet World Media in an all-cash tender offer.
Following its purchase of Mecklermedia, Internet World Media caused iWorld
Corporation to be merged into internet.com LLC, a newly-formed Delaware limited
liability company. Internet World Media then sold 80.1% of its membership
interest in internet.com to Alan M. Meckler (including four trusts for the
benefit of his children) for a total of $18.0 million in cash. Internet World
Media retained a 19.9% interest in internet.com LLC and a warrant to acquire up
to an additional 128 membership units in internet.com LLC (representing
2,075,634 shares of our common stock) for up to $3.0 million.
 
The preliminary allocation of the purchase price is as follows (in thousands):

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
FOR THE PERIOD FROM INCEPTION (NOVEMBER 24, 1998) THROUGH DECEMBER 31, 1998 AND
             FOR THE THREE MONTHS ENDED MARCH 31, 1999 (UNAUDITED)
 
Upon consummation of the acquisition in November 1998, internet.com immediately
expensed $2.0 million, which was determined by an independent appraiser,
representing a purchased in-process research and development project that had
not yet reached technological feasibility and had no alternative future use.
This project related to a system that integrates Web site content management and
an application server environment. Estimated costs to complete this project,
which are expected to be incurred in 1999, are approximately $300,000. The
development of the in-process project is expected to be completed during 1999.
 
The value assigned to in-process technology was determined by estimating the
costs to develop the purchased in-process technology into a viable product,
estimating the percentage of completion of the project, estimating the resulting
net cash flows from the project and discounting the net cash flows back to their
present values. The discount rate includes a factor that takes into account the
uncertainty surrounding the successful development of the purchased in-process
technology. The following assumptions were used, among others, to estimate
discounted net cash flows:
 
      -      The project was approximately 75% complete at the time of the
             Second Merger. The remaining work to be performed relates to a
             combination of designing and coding, content conversion and
             testing.
 
      -      The projected cost savings were based on management's estimates of
             the time costs savings and life expectancy for the product. The
             average compound annual growth rates for the projected cost savings
             are estimated to be 200% in 2000 and 20% in 2001. The projected
             cost of revenues, advertising, promotion and selling expenses,
             general and administrative expenses and income taxes were estimated
             by management based on expected and historical operating
             characteristics. In addition, the appraiser performed due diligence
             on management's estimates to test their reasonableness.
 
      -      A risk-adjusted discount rate was used to discount the net cash
             flows back to their present value. Giving primary consideration to
             rates of return required for venture capital investments, an
             overall 50% after-tax discount rate was selected as the basis for
             discounting net cash flows to arrive at indications of value for
             determining the appropriate discount rate to be used in the
             valuation of the project. Cash flows were adjusted to reflect the
             75% completion level based on interpretation of recent guidance
             from the Securities and Exchange Commission regarding the
             allocation of purchased in-process research and development.
 
      -      If this project is not successfully developed within a reasonable
             period of time or on a timely basis, the results of operations of
             internet.com would suffer in future periods. Management believes
             that the assumptions used in the valuation of the purchased in-
             process research and development reasonably estimate the future
             benefits attributable to the purchased in-process technology.
             However, no assurance can be given that technological viability of
             this project will be achieved or that actual results will not
             deviate from those assumptions in future periods.
 
Since all of internet.com's products and services relate to providing
Internet-related information to Internet industry and Internet technology
professionals, Web developers and experienced Internet users, its success is
dependent on the continued growth of the Internet.

On April 13, 1999, the Board of Directors authorized internet.com to proceed

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
REVENUE RECOGNITION. internet.com barters portions of the unsold advertising
impressions generated by its Web sites, e-mail newsletters, online discussion
forums and moderated e-mail discussion lists for advertising and promotion in
media properties owned by Penton Media and other third parties. internet.com
does not record any revenues or expenses for such barter because it does not
receive or expend any cash, nor does it incur any costs to fulfill such barter
and because such unsold advertising impressions would otherwise have no value.
Therefore, the recording of any barter would result in an overstatement of
revenues and expenses. Management also believes that not recording any revenues
or expenses for barter more accurately reflects its actual results of operations
and as a result provides a more meaningful presentation to the users of its
financial statements.
 
internet.com generates its revenues from four primary sources: the sale of
advertising on its Web sites, e-mail newsletters, online discussion forums and
moderated e-mail discussion lists; e-commerce agreements; licensing of editorial
content, brands and software; and subscriptions to paid e-mail newsletters.
 
       ADVERTISING REVENUES. Advertising revenue is recognized ratably in the
       period the advertising is displayed, provided that no significant company
       obligations remain and collection of the resulting receivable is
       probable. Company obligations typically include guarantees of a minimum
       number of advertising impressions, or times that an advertisement is
       viewed by users of internet.com's Web sites and related Internet media
       properties.
 
       E-COMMERCE REVENUES. E-commerce agreements generally include a fixed fee
       for advertising and/or revenue sharing for sales made by the e-commerce
       vendors. The advertising component of these agreements is recognized
       ratably in the period the advertising is displayed, provided that no
       significant company obligations remain and collection of the remaining
       receivable is probable. The revenue sharing component of these agreements
       is recognized as revenue in the period that the underlying sale is made
       by the e-commerce vendor.
 
       LICENSING REVENUES. The licensing agreements vary, with internet.com
       generating fixed fees and royalties for monthly access to editorial
       content, brands and software produced by internet.com. Such amounts are
       recognized as revenue in the month earned.
 
       PAID SUBSCRIPTION REVENUES. Subscription revenue relates to customer
       subscriptions to our paid e-mail newsletters. Revenue from subscriptions
       is recognized ratably over the subscription period. Deferred revenues
       relate to the portion of collected subscription fees which have not yet
       been recognized as revenue.
 
USE OF ESTIMATES IN THE FINANCIAL STATEMENTS. The preparation of financial
statements in conformity with generally accepted accounting principles requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
FOR THE PERIOD FROM INCEPTION (NOVEMBER 24, 1998) THROUGH DECEMBER 31, 1998 AND
             FOR THE THREE MONTHS ENDED MARCH 31, 1999 (UNAUDITED)
 
INTERIM FINANCIAL DATA. The accompanying financial statements as of, and for the
three months ended, March 31, 1999 are unaudited. In the opinion of management,
these interim statements have been prepared on the same basis as the audited
financial statements and include all adjustments, consisting only of normal
recurring adjustments, necessary for the fair presentation of the results of the
interim periods. The financial and other data disclosed in these notes to the
financial statements for these periods are also unaudited. The results of the
operations for the interim periods are not necessarily indicative of the results
to be expected for any future periods.
 
CONCENTRATION OF CREDIT RISK. Financial instruments that potentially subject
internet.com to a significant concentration of credit risk consist primarily of
cash and accounts receivable. internet.com deposits all its cash with a single
financial institution. Most of internet.com's accounts receivable as of December
31, 1998 and March 31, 1999 are from Internet-related businesses.
 
At December 31, 1998, three customers accounted for 38% of accounts receivable.
At March 31, 1999, three customers accounted for 21% of accounts receivable. For
the period from inception (November 24, 1998) through December 31, 1998, one
customer accounted for 25% of revenues. For the three months ended March 31,
1999, one customer accounted for 13% of revenues.
 
CASH AND CASH EQUIVALENTS. internet.com considers all highly liquid investments
purchased with original maturities of three months or less to be cash
equivalents. At December 31, 1998 and March 31, 1999, internet.com had no
investments with maturities greater than three months.
 
FINANCIAL INSTRUMENTS. The recorded amounts of financial instruments such as
cash and cash equivalents, accounts receivable, accounts payable and debt
approximate their fair values due to their short maturities.
 
PROPERTY AND EQUIPMENT. Depreciation of computer equipment and software is
provided for by the straight-line method over estimated useful lives ranging
from three to five years. Depreciation of furniture, fixtures and equipment is
provided for by the straight-line method over estimated useful lives ranging
from five to ten years.
 
Maintenance and repair expenditures are charged to appropriate expense accounts
in the period incurred; replacements, renewals and betterments are capitalized.
Upon the sale or other disposition of property, the cost and accumulated
depreciation of such properties are eliminated from the accounts and the gains
or losses thereon are reflected in operations.
 
INTANGIBLE ASSETS. Intangible assets, primarily consisting of goodwill, are
being amortized using the straight-line method over three years.
 
IMPAIRMENT OF LONG-LIVED ASSETS. Long-lived assets and certain identifiable
intangibles are reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable. An impairment loss is recognized when the sum of undiscounted
expected future cash flows is less than the carrying amount of such assets. The
measurement for such impairment loss is based on the fair value of the assets.
internet.com believes no such impairment exists as of March 31, 1999.

             FOR THE THREE MONTHS ENDED MARCH 31, 1999 (UNAUDITED)
 
ACCRUED WEB SITE ACQUISITION PAYMENTS. Accrued Web site acquisition payments
consist of future amounts payable under purchase agreements for Web sites and
related Internet media properties.
 
INCOME TAXES. internet.com accounts for income taxes in accordance with the
provisions of Statement of Financial Accounting Standards No. 109, "Accounting
for Income Taxes" ("SFAS 109"). SFAS 109 requires an asset and liability
approach which requires the recognition of deferred tax assets and deferred tax
liabilities for the expected future tax consequences of temporary differences
between the carrying amounts and the tax bases of assets and liabilities.
Valuation allowances will be established when necessary to reduce deferred tax
assets to the amount expected to be realized.
 
No benefit for federal and state income taxes is reported in the financial
statements as internet.com has elected to be taxed as a partnership prior to the
reorganization of the limited liability company into a corporation, which will
take effect immediately prior to the closing of the IPO. Therefore, the federal
and state income tax effects of internet.com's results of operations are
recorded by the members in their respective income tax returns.
 
ADVERTISING COSTS. internet.com expenses advertising costs as incurred.
Advertising expense was $44,000 for the period from inception (November 24,
1998) through December 31, 1998 and $189,000 for the three months ended March
31, 1999.
 
RECENT ACCOUNTING PRONOUNCEMENTS. In June 1997, the Financial Accounting
Standards Board ("FASB") issued Statement of Financial Accounting Standards No.
131, "Disclosures about Segments of an Enterprise and Related Information"
("SFAS No. 131"), which establishes standards for reporting information about
operating segments in annual financial statements. It also establishes standards
for related disclosures about products and services, geographic areas and major
customers. SFAS No. 131 is effective for fiscal years beginning after December
15, 1997. The adoption of this standard is not expected to have an impact on the
presentation of the financial statements of internet.com.
 
In March 1998, the American Institute of Certified Public Accountants ("AICPA")
issued Statement of Position 98-1, "Accounting for the Cost of Computer Software
Developed or Obtained for Internal Use" ("SOP 98-1"). SOP 98-1 is effective for
financial statements for years beginning after December 15, 1998. SOP 98-1
provides guidance over accounting for computer software developed or obtained
for internal use including the requirement to capitalize specified costs and
amortization of such costs. The adoption of this standard is not expected to
have a material effect on internet.com's capitalization policy.
 
In April 1998, the AICPA issued Statement of Position 98-5, "Reporting on the
Costs of Start-Up Activities" ("SOP 98-5"). SOP 98-5, which is effective for
fiscal years beginning after December 15, 1998, provides guidance on the
financial reporting of start-up costs and organization costs. It requires costs
of start-up activities and organization costs to be expensed as incurred. As
internet.com has expensed these costs historically, the adoption of this
statement is not expected to have a significant impact on internet.com's results
of operations, financial position or cash flows.

5. ACQUISITIONS OF ASSETS
 
internet.com made two acquisitions for a total of $580,000 during the period
from inception (November 24, 1998) through December 31, 1998 and one acquisition
for $175,000 during the three months ended March 31, 1999. These acquisitions
were accounted for as purchases. Two of these acquisitions provide for
contingent payments to be made one year after the acquisition date based upon
the achievement of certain objectives. The acquired Web sites and related
Internet media properties had no tangible assets or liabilities. Therefore, the
entire purchase price has been recorded as goodwill and is being amortized over
its estimated useful life for these acquisitions. The pro forma results for the
period from inception (November 24, 1998) through December 31, 1998 and for the
three months ended March 31, 1999, assuming these acquisitions had been made at
the beginning of the period, would not be materially different from reported
results.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors of internet.com LLC:
 
We have audited the accompanying balance sheets of the iWorld division of
Mecklermedia Corporation, as of September 30, 1997 and 1998, and the related
statements of operations, changes in division equity and cash flows for each of
the three years in the period ended September 30, 1998 and for the period
October 1, 1998 through November 23, 1998. These financial statements are the
responsibility of the company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of the iWorld division of
Mecklermedia Corporation, as of September 30, 1997 and 1998, and the results of
its operations and its cash flows for each of the three years in the period
ended September 30, 1998, and for the period October 1, 1998 through November
23, 1998, in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
             FOR THE YEARS ENDED SEPTEMBER 30, 1996, 1997 AND 1998
       AND FOR THE PERIOD FROM OCTOBER 1, 1998 THROUGH NOVEMBER 23, 1998
           AND FOR THE THREE MONTHS ENDED MARCH 31, 1998 (UNAUDITED)
 
1. ORGANIZATION AND NATURE OF BUSINESS
 
The accompanying financial statements and related notes reflect the carved-out
historical results of operations and financial position of the iWorld division
of Mecklermedia Corporation ("iWorld"). The Statements of Operations include all
revenues and costs directly attributable to iWorld, including costs for
facilities, functions and services used by iWorld at shared sites and
allocations of costs for certain administrative functions and services performed
by centralized departments within Mecklermedia Corporation.
 
iWorld consisted of a network of Web sites and related Internet media properties
that delivered the latest news and resources for the Internet industry,
directories of Internet products and services, back issues of the Mecklermedia
Corporation's print publications, and information about Mecklermedia
Corporation's trade shows.
 
Costs were allocated to iWorld based on management's estimate of costs
attributable to the operation of the business. Such costs are not necessarily
indicative of the costs that would have been incurred if iWorld had been a
separate entity.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
REVENUE RECOGNITION. iWorld bartered portions of the unsold advertising
impressions generated by its Web sites, e-mail newsletters, online discussion
forums and moderated e-mail discussion lists for advertising and promotion in
media properties owned by third parties. iWorld did not record any revenues or
expenses for such barter because it did not receive or expend any cash, nor does
it incur any costs to fulfill such barter and because such unsold advertising
impressions would otherwise have no value. Therefore, the recording of any
barter would result in an overstatement of revenues and expenses. Management
also believed that not recording any revenues or expenses for barter more
accurately reflected its actual results of operations and as a result provided a
more meaningful presentation to the users of its financial statements.
 
iWorld generated its revenues from four primary sources: the sale of advertising
on its Web sites, e-mail newsletters, online discussion forums and moderated
e-mail discussion lists; e-commerce agreements; licensing of editorial content,
brands and software; and subscriptions to paid e-mail newsletters.
 
      ADVERTISING REVENUES. Advertising revenue is recognized ratably in the
      period the advertising is displayed, provided that no significant company
      obligations remain and collection of the resulting receivable is probable.
      Company obligations typically include guarantees of a minimum number of
      advertising impressions, or times that an advertisement is viewed by users
      iWorld's Web sites and related Internet media properties.
 
      E-COMMERCE REVENUES. E-commerce agreements generally include a fixed fee
      for advertising and/or revenue sharing for sales made by the e-commerce
      vendors. The advertising component of these agreements is recognized
      ratably in the period the advertising is displayed, provided

                             (PREDECESSOR BUSINESS)
 
                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
             FOR THE YEARS ENDED SEPTEMBER 30, 1996, 1997 AND 1998
       AND FOR THE PERIOD FROM OCTOBER 1, 1998 THROUGH NOVEMBER 23, 1998
           AND FOR THE THREE MONTHS ENDED MARCH 31, 1998 (UNAUDITED)
 
      that no significant company obligations remain and collection of the
      remaining receivable is probable. The revenue sharing component of these
      agreements is recognized as revenue in the period that the underlying sale
      is made by the e-commerce vendor.
 
      LICENSING REVENUES. The licensing agreements vary, with iWorld typically
      generating fixed fees and royalties for monthly access to editorial
      content produced by iWorld. Such amounts are recognized as revenue in the
      month earned.
 
      PAID SUBSCRIPTION REVENUES. Subscription revenue relates to customer
      subscriptions to our paid e-mail newsletters. Revenue from subscriptions
      is recognized ratably over the subscription period. Deferred revenues
      relate to the portion of collected subscription fees which have not yet
      been recognized as revenue.
 
USE OF ESTIMATES IN THE FINANCIAL STATEMENTS. The preparation of financial
statements in conformity with generally accepted accounting principles requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.
 
INTERIM FINANCIAL DATA. The accompanying financial statements for the three
months ended March 31, 1998 are unaudited. In the opinion of management, these
interim statements have been prepared on the same basis as the audited financial
statements and include all adjustments, consisting only of normal recurring
adjustments, necessary for the fair presentation of the results of the interim
periods. The financial and other data disclosed in these notes to the financial
statements for these periods are also unaudited. The results of the operations
for the interim periods are not necessarily indicative of the results to be
expected for any future periods.
 
CONCENTRATION OF CREDIT RISK. Financial instruments that potentially subject
iWorld to a significant concentration of credit risk consist primarily of cash
and accounts receivable. iWorld deposits all its cash primarily with a single
financial institution. Most of iWorld's accounts receivable as of September 30,
1996, 1997, and 1998 are from Internet-related businesses.
 
At September 30, 1997, and 1998, four and three customers accounted for 33% and
28% of accounts receivable, respectively. For the year ended September 30, 1996,
one customer accounted for 15% of revenues. For the year ended September 30,
1997, two customers accounted for 38% of revenues. For the year ended September
30, 1998, one customer accounted for 17% of revenues. For the three months ended
March 31, 1998, one customer accounted for 14% of revenues. For the period from
October 1, 1998 through November 23, 1998, one customer accounted for 21% of
revenues.
 
FINANCIAL INSTRUMENTS. The recorded amounts of financial instruments such as
cash and cash equivalents, accounts receivable and accounts payable approximate
their fair values due to their short maturities.
 
PROPERTY AND EQUIPMENT. Depreciation of computer equipment and software is
provided for by the straight-line method over estimated useful lives ranging
from three to five years. Depreciation of

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
             FOR THE YEARS ENDED SEPTEMBER 30, 1996, 1997 AND 1998
       AND FOR THE PERIOD FROM OCTOBER 1, 1998 THROUGH NOVEMBER 23, 1998
           AND FOR THE THREE MONTHS ENDED MARCH 31, 1998 (UNAUDITED)
 
furniture, fixtures and equipment is provided for by the straight-line method
over estimated useful lives ranging from five to ten years. Amortization of
leasehold improvements is provided for over the lesser of the term of the
related lease or the estimated useful life of the improvement.
 
Maintenance and repair expenditures are charged to appropriate expense accounts
in the period incurred; replacements, renewals and betterments are capitalized.
Upon the sale or other disposition of property, the cost and accumulated
depreciation of such properties are eliminated from the accounts and the gains
or losses thereon are reflected in operations.
 
INTANGIBLE ASSETS. Intangible assets, primarily consisting of goodwill,
resulting from acquisitions of Web sites and related Internet media properties
are being amortized using the straight-line method over periods ranging from
three to five years.
 
INCOME TAXES. The taxable losses of iWorld for each of the three years in the
period ended September 30, 1998 and for the period October 1, 1998 through
November 23, 1998 were included in the Mecklermedia Corporation's consolidated
income tax returns. For all periods presented, deferred income taxes and related
income tax expenses have been recorded by applying the asset and liability
approach to each component of iWorld as if it were a separate taxpayer. Under
this approach, deferred tax assets and liabilities represent the expected future
tax consequences of carryforwards and temporary differences between the carrying
amounts and the tax bases of assets and liabilities.
 
ADVERTISING COSTS. iWorld expensed advertising costs as incurred. Advertising
expense was $62,000, $163,000, $320,000, $41,000 and $167,000 for the three
years ended September 30, 1996, 1997, 1998, for the three months ended March 31,
1998 and for the period October 1, 1998 through November 23, 1998, respectively.

5. ACQUISITIONS OF ASSETS
 
iWorld acquired six, two, nine, two and four Web sites and related Internet
media properties for $230,000, $1.4 million, $3.9 million, $1.2 million and $2.4
million during the years ended September 30, 1996, 1997, 1998, the three months
ended March 31, 1998 and the period from October 1, 1998 through November 23,
1998, respectively. These acquisitions were accounted for as purchases. Certain
of these acquisitions provide for contingent payments to be made one year after
the acquisition dates based upon the achievement of certain objectives. The
acquired Web sites and related Internet media properties had no tangible assets
or liabilities and therefore the entire purchase price has been recorded as
goodwill and is being amortized over its estimated useful life. The pro forma
results for the years ended September 30, 1996, 1997 and 1998 and the period
from October 1, 1998 through November 23, 1998, assuming these acquisitions had
been made at the beginning of the period, would not be materially different from
reported results.
 
6. INCOME TAXES
 
The operating results of iWorld were included in the consolidated tax returns of
Mecklermedia. The methodology for allocating income tax expense to iWorld is set
forth in Note 2. For all periods presented, valuation allowances were recorded
against income tax benefits generated from the losses from iWorld.

7. EMPLOYEE BENEFIT PLAN
 
iWorld participated in Mecklermedia's defined contribution plan which qualified
under Section 401(k) of the Internal Revenue Code for employees meeting certain
service requirements. The plan allowed eligible employees to contribute up to
15% of their compensation to the plan. At the discretion of Mecklermedia's board
of directors, Mecklermedia was also able to make contributions dependent on
profits each year for the benefit of all eligible employees under the plan.
There were no discretionary contributions for any of the periods presented.
 
8. RELATED PARTY TRANSACTIONS
 
The accompanying financial statements include costs for cash management,
accounting, legal and network operations that were provided to iWorld by
Mecklermedia, in addition to allocated costs for facility charges at shared
sites, including rent and equipment usage. Costs for cash management accounting,
legal and network operations have been allocated to iWorld based on internet.com
management's estimated percentage of the time spent by Mecklermedia employees on
iWorld to total department time. The costs for facility charges are based on the
percentage of usage by the iWorld Division of Mecklermedia to the overall costs.
Such allocations are not necessarily indicative of the costs that would have
been incurred if iWorld had been a stand-alone entity.
 
Costs allocated to iWorld by Mecklermedia were approximately $440,000, $777,000,
$1,185,000, $331,000 and $150,000 for the years ended September 30, 1996, 1997,
1998, for the three months ended March 31, 1998 and for the period from October
1, 1998 through November 23, 1998, respectively. For the year ended September
30, 1996, allocated costs of $23,000 and $417,000 were included in cost of
revenues and general and administrative expenses, respectively. For the three
months ended March 31, 1998, allocated costs of $26,000 and $305,000 were
included in cost of revenues and general and administrative expenses,
respectively. For the year ended September 30, 1997, allocated costs of $67,000
and $710,000 were included in cost of revenues and general and administrative
expenses, respectively. For the year ended September 30, 1998, allocated costs
of $100,000 and $1,085,000 were included in cost of revenues and general and
administrative expenses, respectively. All of the allocated costs for the period
from October 1, 1998 through November 23, 1998, were included in general and
administrative expenses. Management believes the allocation methods used are
reasonable.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
Section 145 of the Delaware General Corporation Law authorizes a court to award,
or a corporation's board of directors to grant, indemnity to directors and
officers in terms sufficiently broad to permit such indemnification under
certain circumstances for liabilities including reimbursement for expenses
incurred arising under the Securities Act of 1933, as amended.
 
As permitted by the Delaware General Corporation Law, the Registrant's Amended
and Restated Certificate of Incorporation includes a provision that eliminates
the personal liability of its directors for monetary damages for breach of
fiduciary duty as a director, except for liability (i) for any breach of the
director's duty of loyalty to the Registrant or its stockholders, (ii) for acts
or omissions not in good faith or that involve intentional misconduct or a
knowing violation of law, (iii) under section 174 of the Delaware General
Corporation Law regarding unlawful dividends and stock purchases or (iv) for any
transaction from which the director derived an improper personal benefit.
 
As permitted by the Delaware General Corporation Law, the Bylaws of the
Registrant provide that (i) the Registrant is required to indemnify its
directors and officers to the fullest extent permitted by the Delaware General
Corporation Law, subject to certain very limited exceptions, (ii) the Registrant
may indemnify its other employees and agents as set forth in the Delaware
General Corporation Law, (iii) the Registrant is required to advance expenses,
as incurred, to its directors and executive officers in connection with a legal
proceeding to the fullest extent permitted by the Delaware General Corporation
Law, subject to certain very limited exceptions and (iv) the rights conferred in
the Bylaws are not exclusive.
 
The Registrant intends to enter into Indemnification Agreements with each of its
directors and executive officers to give such directors and officers additional
contractual assurances regarding the scope of the indemnification set forth in
the Registrant's Amended and Restated Certificate of Incorporation and to
provide additional procedural protections. At present, there is no pending
 
                                      II-1
<PAGE>
litigation or proceeding involving a director, officer or employee of the
Registrant regarding which indemnification is sought, nor is the Registrant
aware of any threatened litigation that may result in claims for
indemnification.
 
Reference is also made to Section 6 of the purchase agreement, which provides
for the indemnification of officers, directors and controlling persons of the
Registrant against certain liabilities. The indemnification provision in the
Registrant's Amended and Restated Certificate of Incorporation, Bylaws and the
Indemnification Agreements entered into between the Registrant and each of its
directors and executive officers may be sufficiently broad to permit
indemnification of the Registrant's directors and executive officers for
liabilities arising under the Securities Act of 1933, as amended.
 
The Registrant, with approval by the Registrant's Board of Directors, expects to
obtain directors' and officers' liability insurance.
 
Reference is made to the following documents filed as exhibits to this
registration statement regarding relevant indemnification provisions described
above and elsewhere herein:

ITEM 17. UNDERTAKINGS.
 
The undersigned Registrant hereby undertakes to provide to the underwriters at
the closing specified in the purchase agreement certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.
 
Insofar as indemnification for liabilities arising under the Securities Act of
1933, as amended, may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the provisions described under Item 14
above, or otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Securities Act of 1933, as amended, and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act of 1933, as amended, and will be
governed by the final adjudication of such issue.
 
The undersigned Registrant hereby undertakes that:
 
(1) For purposes of determining any liability under the Securities Act of 1933,
    as amended, the information omitted from the form of prospectus filed as
    part of this registration statement in reliance upon Rule 430A and contained
    in a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1)
    or (4) or 497(h) under the Securities Act of 1933, as amended, shall be
    deemed to be part of this registration statement as of the time it was
    declared effective.
 
(2) For the purpose of determining any liability under the Securities Act of
    1933, as amended, each post-effective amendment that contains a form of
    prospectus shall be deemed to be a new registration statement relating to
    the securities offered therein, and the offering of such securities at that
    time shall be deemed to be the initial bona fide offering thereof.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
                        ON FINANCIAL STATEMENT SCHEDULE
 
To the Board of Directors of internet.com LLC:
 
We have audited in accordance with generally accepted auditing standards the
financial statements of the iWorld division of Mecklermedia Corporation included
in this registration statement and have issued our report thereon dated April 5,
1999. Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The financial statement schedule on the
following page is the responsibility of the company's management and is
presented for purposes of complying with the Securities and Exchange
Commission's rules and is not part of the basic financial statements. This
schedule has been subjected to the auditing procedures applied in the audits of
the basic financial statements and, in our opinion, fairly states in all
material respects the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.
