  The following summary is qualified in its entirety by the information
appearing elsewhere in this Prospectus Supplement and the accompanying
Prospectus and in the documents and financial statements incorporated therein
by reference. An investment in the securities offered hereby involves
significant risks. See "Risk Factors" in this Prospectus Supplement.
 
                                  THE COMPANY
 
  The Company is one of the largest operators of cable television systems in
the United States, with approximately 2,752,000 subscribers in 19 states as of
March 31, 1996, based on the number of basic subscribers in systems which the
Company manages and which it owns or in which it has investments. The Company
also has ownership interests in companies that produce and distribute national
and regional programming services and provide advertising sales services for
the cable television industry. The Company was formed in 1985 to effect a
reorganization of its predecessors.
 
CABLE TELEVISION
 
  The cable television systems that are majority owned and managed by the
Company (the "Company's cable television systems") served approximately
2,085,000 subscribers as of March 31, 1996 in New York, Ohio, Connecticut, New
Jersey, Michigan and Massachusetts. In addition, the Company has non-majority
investments in and manages cable television systems which served approximately
667,000 subscribers as of March 31, 1996 in Alabama, Arkansas, Florida,
Illinois, Kansas, Kentucky, Maine, Massachusetts, Mississippi, Missouri, New
Jersey, New York, North Carolina, Oklahoma, Pennsylvania and Tennessee. The
Company's cable television systems have generally been characterized by
relatively high revenues per subscriber ($37.28 for March 1996) and a high
ratio of premium service units to basic subscribers (1.8:1 for March 1996). In
calculating revenue per subscriber, the Company includes only recurring service
revenues and excludes installation charges and certain other revenues such as
advertising, pay-per-view and home shopping revenues.
 
  On May 10, 1996, the Company entered into an agreement with Warburg, Pincus
Investors, L.P. ("Warburg") to acquire (the "Pending Warburg Transactions")
from Warburg the interests in A-R Cable Services, Inc. ("A-R Cable"), A-R Cable
Partners, Cablevision of Newark and Cablevision of Framingham Holdings, Inc.
("CFHI") that the Company does not already own. See "Recent Developments--
Pending Warburg Transactions".
 
PROGRAMMING SERVICES
 
  The Company conducts its programming activities through Rainbow Programming
Holdings, Inc. ("Rainbow Programming"), its wholly-owned subsidiary, and
through subsidiaries of Rainbow Programming in partnership with certain
unaffiliated entities, including National Broadcasting Company, Inc. ("NBC")
and Liberty Media Corporation. Rainbow Programming's businesses include eight
regional SportsChannel services, four national entertainment services (American
Movie Classics, Bravo, MuchMusic and the Independent Film Channel), Rainbow
News 12 (regional news services serving suburban areas surrounding New York
City) and the sports services of Prime SportsChannel Networks (Prime Network
and NewSport). Rainbow Programming also owns an interest in Madison Square
Garden, L.P.
 
ADVERTISING SERVICES
 
  Rainbow Advertising Sales Corporation sells advertising time to national,
regional and local advertisers on behalf of the Company's cable television
systems and the SportsChannel and Rainbow News 12 programming services, as well
as on behalf of unaffiliated cable television systems.

                               redeemable, at the option of the Company, in
                               whole or in part, at the redemption prices set

Subordination...............  Subordinated to all existing and future Senior
                               Indebtedness (as defined) of the Company. The
                               Debentures will rank pari passu with the
                               Company's $275,000,000 of 10 3/4% Senior
                               Subordinated Debentures due 2004, the Company's
                               $200,000,000 of 9 7/8% Senior Subordinated
                               Debentures due 2013, the Company's $150,000,000
                               of 9 7/8% Senior Subordinated Debentures due
                               2023 and the Company's $300,000,000 of 9 1/4%
                               Senior Subordinated Notes due 2005
                               (collectively, the "Existing Debentures") and
                               the Company's $150,000,000 of 9 7/8% Senior
                               Subordinated Notes due 2006 (the "Notes")
                               offered concurrently herewith. The amount of
                               Senior Indebtedness outstanding at March 31,
                               1996, adjusted to give pro forma effect to the
                               transactions described under "Capitalization"
                               and the application of the estimated net
                               proceeds to the Company from the offering of the
                               Debentures and the Notes offered concurrently
                               herewith, would have been approximately $569.4
                               million. At March 31, 1996, the Company had
                               outstanding, adjusted to give pro forma effect
                               to the transactions described under
                               "Capitalization", $1,663 million of senior
                               subordinated indebtedness and obligations
                               (including $339.7 million of indebtedness of
                               subsidiaries guaranteed by the Company) that
                               would have ranked pari passu with the
                               Debentures. Also, at March 31, 1996,
                               consolidated subsidiaries of the Company had
                               outstanding, adjusted to give pro forma effect
                               to the transactions described under
                               "Capitalization", approximately $1,346 million
                               of indebtedness (not including $339.7 million of
                               indebtedness of subsidiaries guaranteed by the
                               Company, described above) which, insofar as the
                               assets of those subsidiaries are concerned,
                               would have been effectively senior to the
                               Debentures.
 
Certain Restrictions........  The Indenture for the Debentures, among other
                               things, contains restrictions (with certain
                               exceptions) on the ability of the Company and
                               its Restricted Subsidiaries (as defined) to
                               incur additional indebtedness, make certain
                               dividend payments or payments to redeem or
                               retire capital stock, invest in Unrestricted
                               Subsidiaries (as defined) or affiliates, engage
                               in certain
 
                                      S-4
<PAGE>
 
                               transactions with affiliates and merge or
                               consolidate with or transfer all or
                               substantially all of their assets to another
                               entity. The Indenture also prohibits the Company
                               from issuing any indebtedness that is senior in
                               right of payment to the Debentures and expressly
                               subordinate in right of payment to any other
                               indebtedness of the Company.
 
Absence of Public Market....  There is no public market for the Debentures. The
                               Company does not intend to apply for listing of
                               the Debentures on any securities exchange or for
                               quotation through the National Association of
                               Securities Dealers Automated Quotation System.
                               Although Bear, Stearns & Co. Inc., Merrill
                               Lynch, Pierce, Fenner & Smith Incorporated and
                               Morgan Stanley & Co. Incorporated have informed
                               the Company that they currently intend to make a
                               market in the Debentures, they are not obligated
                               to do so, and any such market making may be
                               discontinued at any time without notice.
                               Accordingly, there can be no assurance as to the
                               development or liquidity of any market for the
                               Debentures.
 
Concurrent Offering; Use of
Proceeds....................
                              Concurrently with the offering of the Debentures,
                               the Company is offering $150,000,000 aggregate
                               principal amount of the Notes (the "Other
                               Offering"). The net proceeds to be received by
                               the Company from the Offering and the Other
                               Offering (estimated to be $388.6 million in the
                               aggregate) will initially be applied to repay
                               borrowings under the Company's principal bank
                               credit agreement (the "Credit Agreement"). The
                               Company expects to reborrow amounts repaid under
                               the Credit Agreement in the future in connection
                               with the Pending Warburg Transactions and for
                               general corporate purposes. The Company expects
                               to raise additional funds in the future. See
                               "Use of Proceeds". The consummation of the Other
                               Offering is not a condition to the consummation
                               of this Offering, nor is the consummation of
                               this Offering a condition to the consummation of
                               the Other Offering.

(1) The consolidated statement of operations, balance sheet and statistical
    data reflect (i) the deconsolidation of A-R Cable, effective as of January
    1, 1992, as a result of the restructuring of A-R Cable, (ii) the
    acquisition of Cablevision of New York City ("Cablevision of NYC"),
    effective as of July 10, 1992, and (iii) various acquisitions of cable
    television systems and other businesses during the periods presented. (See
    "Business--Cable Television Operations" in the Form 10-K and "Condensed Pro
    Forma Consolidated Financial Information" herein.) Acquisitions made by the
    Company during the periods presented were accounted for under the purchase
    method of accounting and, accordingly, the acquisition costs were allocated
    to the net assets acquired based on their fair value, except for the
    acquisition of partnership interests in Cablevision of NYC from Charles F.
    Dolan and entities affiliated with him, which were recorded at Mr. Dolan's
    and such entities' historical costs. Acquisitions are reflected in the
    consolidated statement of operations, balance sheet and statistical data
    from the time of acquisition. Certain reclassifications have been made to
    the 1991 financial statement amounts to conform to the 1992 presentation.
(2) The Company recorded a one-time charge in the first quarter of 1994 to
    provide for employee severance and related costs resulting from a
    restructuring of its operations.
(3) In 1992, the Company recognized a $50.0 million loss in connection with
    Rainbow Programming's commitment in respect of its venture with NBC
    relating to the 1992 Summer Olympics, which the Company paid in January
    1993.
(4) In connection with the 1992 reorganization of V Cable, Inc. ("V Cable"),
    the Company redeemed A-R Cable's redeemable preferred stock, incurring a
    loss of $20 million.
(5) In connection with the 1992 reorganization of V Cable, the Company wrote
    off approximately $7.5 million of deferred financing costs related to the
    debt of V Cable. Also, a portion of the Company's deferred financing costs
    of approximately $4.8 million in 1992 and $1.0 million in 1993, related to
    the replacement of bank debt with subordinated debt, were written off. In
    October 1994, the Company entered into a new bank credit agreement and
    redeemed $200 million of its reset debentures. The related deferred
    financing costs and unamortized discount relating to each were written off
    (the portions relating to Cablevision of NYC and Cablevision of New Jersey
    amounting to $3.2 million were written off in 1995) and approximately $2.0
    million in redemption fees was incurred in connection with the redemption
    of the reset debentures. In January 1995, Rainbow Programming amended its
    credit agreement to refinance its existing borrowings and to provide funds
    for the acquisition of SportsChannel Associates and Rainbow News 12,
    resulting in an approximately $2.3 million write-off of deferred financing
    costs.
(6) Homes passed is based upon homes passed by cable actually marketed and does
    not include multiple dwelling units passed by the cable plant that are not
    connected to it.
(7) Basic penetration represents basic service subscribers at the end of the
    period as a percentage of homes passed at the end of the period.
(8) Based on recurring service revenues, excluding installation charges and
    certain other revenues such as advertising, pay-per-view and home shopping
    revenues, for the last month of the period, divided by average basic
    subscribers for that month.

                                 RISK FACTORS
 
  Purchase of the securities offered hereby involves various risks, including
the following principal factors, which, together with the other matters set
forth herein or incorporated by reference herein, should be carefully
considered by prospective investors. The Risk Factors set forth below
supersede the section captioned "Risk Factors" in the accompanying Prospectus.
 
  Substantial Indebtedness and High Degree of Leverage. The Company has
incurred substantial indebtedness, primarily to finance acquisitions and
expansion of its operations and, to a lesser extent, for investments in and
advances to affiliates. The Company's consolidated debt plus the 11 3/4%
Series G Redeemable Exchangeable Preferred Stock (the "Series G Preferred
Stock") and 11 1/8% Series L Redeemable Exchangeable Preferred Stock (the
"Series L Preferred Stock") aggregated approximately $3.6 billion at March 31,
1996 ($4.5 billion on a pro forma basis after giving effect to the
transactions described under "Capitalization") with varying maturities to
2023, including an aggregate of approximately $539.5 million ($1,149.8 million
on a pro forma basis after giving effect to the transactions described under
"Capitalization") maturing on or prior to December 31, 2000. See Note 4 of
Notes to the Consolidated Financial Statements.
 
  Net Losses and Stockholders' Deficiency. The Company reported net losses for
the three months ended March 31, 1996 and 1995 of $76.3 million and $98.5
million, respectively, and for the years ended December 31, 1995, 1994 and
1993 of $317.5 million, $315.2 million and $246.8 million, respectively. At
March 31, 1996, the Company had a stockholders' deficiency of $2.0 billion.
The net losses primarily reflect high levels of interest expense and
depreciation and amortization charges relating to the depreciation of assets
obtained through, and debt incurred to finance, acquisitions. Interest expense
and depreciation and amortization charges remained at a high level throughout
1993, 1994, 1995 and the first quarter of 1996 and will continue at high
levels throughout the remainder of 1996 and future years as a result of
previously completed, pending and future acquisitions, expected capital
expenditures and additional investments in the Company's programming
operations. The Company expects to continue incurring substantial losses for
at least the next several years. See "Management's Discussion and Analysis--
Liquidity and Capital Resources".
 
  Need for Additional Financing. The Company's business requires substantial
investment on a continuing basis to finance capital expenditures and related
expenses for, among other things, upgrade of the Company's cable plant
(including the need to make cable system upgrades mandated by franchise
authorities), the offering of new services and the servicing, repayment or
refinancing of its indebtedness. The Company will require significant
additional financing, through debt and/or equity issuances, to meet its
capital expenditure plans and to pay its debt and preferred stock obligations.
There can be no assurance that the Company will be able to issue additional
debt or obtain additional equity capital on satisfactory terms, or at all, to
meet its future financing needs. See "Management's Discussion and Analysis--
Liquidity and Capital Resources".
 
  Future Capital Expenditures and Commitments. The Company's cable television
systems have commitments for capital expenditures, including major system
upgrades, which will involve substantial expenditures over the next several
years. In addition, the Company, through Rainbow Programming (as defined under
"The Company"), has entered into numerous contracts relating to cable
television programming, including rights agreements with professional and
other sports teams. These contracts typically require substantial payments
over extended periods of time. See Note 11 of Notes to Consolidated Financial
Statements for a discussion of commitments.
 
  Rainbow Programming has the right to acquire interests in Madison Square
Garden, L.P. ("MSG Holdings") from ITT Corporation ("ITT") sufficient to
equalize the interests of ITT and Rainbow Programming in MSG Holdings by
making certain scheduled payments totalling $250 million (plus interest on any
unpaid portion thereof) on specified dates commencing October 1996 and up to
and including March 17, 1997. See "The Company--Programming Services". The
Company and Rainbow Programming may fund the interest payments on the unpaid
portion of the $250 million amount required to equalize the interests of ITT
and Rainbow Programming in MSG Holdings from available cash balances or
amounts borrowed under the Credit Agreement.
 
                                     S-10
<PAGE>
 
Accordingly, the Company funded a $29 million interest payment on March 11,
1996 and the $2.2 million and $1.8 million monthly interest payments on April
15, 1996 and May 15, 1996, respectively, from funds available under the Credit
Agreement. The Company has not yet identified specific funding sources for the
up to $250 million that could be required in connection with the ITT/MSG
Holdings transactions or for the monthly interest payments. The Company also
has a commitment to fund annual payments to Charles F. Dolan related to
Cablevision of New York City ("Cablevision of NYC"). See "Business--
Consolidated Cable Affiliates--Cablevision of New York City" and "Business--
Programming Operations" in the Form 10-K and "Management's Discussion and
Analysis--Liquidity and Capital Resources".
 
  Intangible Assets. The Company had total assets at March 31, 1996 of
approximately $2.6 billion, of which approximately $1.0 billion were
intangible assets, principally franchises, affiliation agreements, excess cost
over fair value of net assets acquired, deferred financing, acquisition and
other costs and deferred interest expense. It is possible that no cash would
be recoverable from the voluntary or involuntary sale of these intangible
assets.
 
  Losses on Investments in and Advances to Certain Affiliates. The Company has
made investments in and advances to certain affiliates in which Charles F.
Dolan has substantial ownership interests. At March 31, 1996, advances (less
applicable reserves) to one such affiliate, Atlantic Cable Television
Publishing Corporation ("Atlantic Publishing"), aggregated approximately $16.7
million. Because Mr. Dolan has a substantial interest in Atlantic Publishing,
an inherent conflict of interest exists with respect to such advances. There
can be no assurances that such advances and any amounts accrued with respect
thereto will be fully recovered or that conflicts of interest will not arise
with respect to the recovery of such amounts.
 
  Atlantic Publishing holds a minority equity interest and a debt interest in
a company that publishes cable television guides which are offered to the
Company's subscribers and to other unaffiliated cable television operators.
Through March 31, 1996, the Company had advanced an aggregate of $16.7 million
to Atlantic Publishing, of which approximately $0.5 million was repaid during
1993, approximately $0.6 million was repaid during 1994 and approximately $1.0
million was repaid during 1995. The Company has written off all advances to
Atlantic Publishing other than approximately $3.1 million. Atlantic Publishing
is owned by a trust for certain Dolan family members; however, the Company has
the option to purchase Atlantic Publishing for an amount equal to the owner's
net investment therein plus interest. The current owner has only a nominal
investment in Atlantic Publishing. See "Business--Other Affiliates--Atlantic
Publishing" in the Form 10-K.
 
  On December 15, 1995, the Company consummated the acquisition of Cablevision
of Boston Limited Partnership ("Cablevision of Boston"). In connection with
the acquisition, all the subordinated advances that the Company had made to
Cablevision of Boston became intercompany indebtedness. As part of the
acquisition of Cablevision of Boston, the Company entered into an agreement
with Mr. Dolan with respect to Mr. Dolan's 0.5% general partnership interest
in Cablevision of Brookline Limited Partnership ("Cablevision of Brookline"),
a partnership affiliated with Cablevision of Boston. The Company acquired the
remaining 99.5% of the partnership interests in Cablevision of Brookline in
the acquisition of Cablevision of Boston. Under the agreement, the Company has
a right of first refusal to acquire Mr. Dolan's 0.5% general partnership
interest and a right to acquire such interest on the earlier to occur of Mr.
Dolan's death or January 1, 2002 at the greater of $10,000 or the book value
of such interest at such date. Mr. Dolan's estate has the right to put the
interest to the Company at the same price. Additionally, in the event of a
change of control of the Company or Cablevision of Brookline, Mr. Dolan will
have the right to put his 0.5% general partnership interest in Cablevision of
Brookline to the Company at the greater of (i) prices declining from $3.9
million for the twelve months ended December 15, 1996 to $10,000 for the
twelve months ended December 15, 2002 and (ii) the book value of such interest
on the date of transfer.
 
  See "Business--Consolidated Cable Affiliates--Cablevision of New York City"
in the Form 10-K for a discussion of the Company's acquisition of
substantially all of Charles F. Dolan's interest in Cablevision of NYC, which
was consummated as described therein in July 1992.

  Voting Control by Majority Stockholders; Disparate Voting Rights. As of
March 31, 1996, Charles F. Dolan beneficially owned and possessed sole voting
power with respect to 259,306 shares or 1.8% of the Company's outstanding
Class A common stock (the "Class A Common Stock") and 2,346,281 shares or
20.3% of the Company's outstanding Class B common stock (the "Class B Common
Stock" and, collectively with the Class A Common Stock, the "Common Stock").
In addition, as of March 31, 1996, an aggregate of 4,000,000 shares or 34.6%
of the outstanding Class B Common Stock were held by two Grantor Retained
Annuity Trusts (the "GRA Trusts") established by Mr. Dolan for estate planning
purposes. Mr. Dolan may be deemed to have beneficial ownership of the shares
of Class B Common Stock held by the GRA Trusts due to his right to reacquire
the Class B Common Stock held by the GRA Trusts by substituting other property
of equivalent value, but, until such event, each of the GRA Trusts, through
their co-trustees (who are family members of Mr. Dolan) has the power to vote
and dispose of the shares of Class B Common Stock held by the GRA Trusts. As a
result of his beneficial ownership of the shares held by the GRA Trusts, as of
March 31, 1996, Mr. Dolan beneficially owned 259,306 shares or 1.8% of the
Company's outstanding Class A Common Stock and 6,346,281 shares or 54.8% of
the Company's outstanding Class B Common Stock. On a combined basis, these
shares represented 25.5% of the total number of shares of both classes of
Common Stock and 49.0% of the total voting power of the classes. Other trusts
established by Mr. Dolan for the benefit of certain Dolan family members, and
as to which Mr. Dolan disclaims beneficial ownership, owned, as of March 31,
1996, an additional 500,000 shares of Class A Common Stock or 3.5% of the
Class A Common Stock and 5,225,928 shares of the Class B Common Stock, or
45.2% of the Class B Common Stock and 40.6% of the total voting power of all
classes of the Common Stock. As a result of this stock ownership, Dolan family
members have the power to elect all the directors subject to election by
holders of the Class B Common Stock, which directors constitute 75% of the
entire Board of Directors of the Company. Moreover, because holders of Class B
Common Stock are entitled to ten votes per share while holders of Class A
Common Stock are entitled to one vote per share, Dolan family members may
control stockholder decisions on matters in which holders of Class A and Class
B Common Stock vote together as a class. These matters include the amendment
of certain provisions of the Company's certificate of incorporation (the
"Certificate of Incorporation") and the approval of fundamental corporate
transactions, including mergers. In addition, because the affirmative vote or
consent of the holders of at least 66 2/3% of the outstanding shares of the
Class B Common Stock, voting separately as a class, is required to approve (i)
the authorization or issuance of any additional shares of Class B Common Stock
and (ii) any amendment, alteration or repeal of any of the provisions of the
Certificate of Incorporation which adversely affects the powers, preferences
or rights of the Class B Common Stock, Dolan family members also have the
power to prevent such issuance or amendment. The voting rights of the Class B
Common Stock beneficially owned by Mr. Dolan will not be modified as a result
of any transfer of legal or beneficial ownership thereof.
 
  Restrictive Covenants. The Company's principal bank credit agreement (the
"Credit Agreement") and certain of the Company's other debt instruments
contain various financial and operating covenants which, among other things,
require the maintenance of certain financial ratios and restrict the Company's
ability to borrow funds from other sources and to utilize funds for various
purposes, including investments in certain subsidiaries. Violation of the
covenants in the Credit Agreement or in the indentures governing the Company's
publicly-issued debentures and notes could result in a default under the
Credit Agreement which would permit the bank lenders thereunder to restrict
the Company's ability to borrow undrawn funds under the Credit Agreement and
to accelerate the maturity of borrowings thereunder. See "Management's
Discussion and Analysis--Liquidity and Capital Resources".
 
  Risks Related to Regulation. The Company's cable television operations may
be adversely affected by government regulation, the impact of competitive
forces and technological changes. In 1992, Congress enacted the 1992 Cable
Act, which represented a significant change in the regulatory framework under
which cable television systems operate. In April 1993 and February 1994, the
Federal Communications Commission ("FCC") ordered reductions in cable
television rates. In June 1995, a Federal appeals court upheld the material
aspects of the FCC's rate regulation scheme. Congress has enacted legislation
(the "Telecommunications Act of 1996") that relaxes the regulation of cable
television rates. The FCC is formulating rules to implement the
Telecommunications Act of 1996. These rules will determine the effect of the
legislation on the Company. See
 
                                     S-12
<PAGE>
 
"Business--Cable Television Operations--Competition" and "Business--Cable
Television Operations--Regulation" in the Form 10-K.
 
  Risk of Competition. Cable operators compete with a variety of distribution
systems, including broadcast television stations, multichannel multipoint
distribution services ("MMDS"), satellite master antenna systems ("SMATV"),
direct broadcast satellite systems ("DBS"), and private home dish earth
stations. For example, CAI Wireless Systems, Inc., an MMDS operator, has
received investments from Bell Atlantic Corporation and NYNEX Corporation and
owns operating systems or spectrum rights in a significant portion of the
Company's systems areas. In addition, four DBS systems are now operational in
the United States and recently AT&T Corp. announced an investment in Hughes
Electronics Corp.'s DirecTv system. The 1992 Cable Act prohibits a cable
programmer that is owned by or affiliated with a cable operator (such as
Rainbow Programming) from unreasonably discriminating among or between cable
operators and other multichannel video distribution systems with respect to
the price, terms and conditions of sale or distribution of the programmer's
service and from unreasonably refusing to sell service to any multichannel
video programming distributor. Cable systems also compete with the entities
that make videotaped movies and programs available for home rental. The 1992
Cable Act regulates the ownership by cable operators of MMDS and SMATV. Under
the Telecommunications Act of 1996, the cross-ownership provisions do not
apply to any cable operator in a franchise area in which a cable operator
faces competition from video programming distributors meeting certain
statutory requirements. In July 1992, the FCC voted to authorize additional
competition to cable television by video programmers using broadband common
carrier facilities constructed by telephone companies. The FCC allowed
telephone companies to take ownership interests of up to 5% in such
programmers. The FCC also reaffirmed an earlier administrative holding, upheld
on appeal by a Federal appeals court, that programmers using such a telephone
company-provided "video dialtone" system would not need to obtain a state or
municipal franchise. Several telephone companies have sought approval from the
FCC to build such "video dialtone" systems. Such a system has been proposed in
several communities in which the Company currently holds a cable franchise and
several of such systems have been approved by the FCC. The Telecommunications
Act of 1996 repeals the "video dialtone" rules, but gives telephone companies
(and cable companies, to the extent permitted by the FCC) the option of
providing video programming to subscribers through "open video systems" that
closely resemble video dialtone systems and that would not require a local
cable franchise. Additional competition to cable systems is possible if the
FCC authorizes the licensing of local multipoint distribution services
("LMDS"). The FCC has proposed to license this type of service to providers.
 
  Competition from Telephone Companies. The 1984 Cable Act barred co-ownership
of telephone companies and cable television systems operating in the same
service areas. Numerous Federal district courts held this prohibition to be
unconstitutional. Several of these decisions have been upheld on appeal. The
Telecommunications Act of 1996 repeals this restriction and permits a
telephone company to provide video programming directly to subscribers in its
telephone service territory, subject to certain regulatory requirements, but
generally prohibits a telephone company from acquiring an in-region cable
operator, except in certain small markets under certain circumstances.
Telephone companies (Ameritech Corp. in Ohio and Southern New England
Telephone Co. in Connecticut) have obtained or applied for local franchises to
construct and operate cable television systems in several communities in which
the Company currently holds cable franchises. Neither the 1984 Cable Act nor
the 1992 Cable Act bars a telephone company from acquiring cable systems
outside its telephone service area, and several Regional Bell operating
companies have purchased or made investments in the cable systems. See
"Business--Cable Television Operations--Regulation" in the Form 10-K.
 
  Risk of Non-Exclusive Franchises and Franchise Renewals. The Company's cable
television systems are operated primarily under nonexclusive franchise
agreements with local government franchising authorities, in some cases with
the approval of state cable television authorities. The Company's business is
dependent on its ability to obtain and renew its franchises. Although the
Company has never lost a franchise as a result of a failure to obtain a
renewal, its franchises are subject to non-renewal or termination under
certain circumstances. In certain cases, franchises have not been renewed at
expiration and the Company operates under temporary licenses while negotiating
renewal terms with the franchising authorities. See "Business--Cable
Television Operations--Franchises" in the Form 10-K.

  Absence of Public Market. The Debentures are a new security for which there
currently is no market. Although Bear, Stearns & Co. Inc., Merrill Lynch,
Pierce, Fenner & Smith Incorporated and Morgan Stanley & Co. Incorporated (the
"Underwriters") have informed the Company that they currently intend to make a
market in the Debentures, they are not obligated to do so and any such market
making may be discontinued at any time without notice. Accordingly, there can
be no assurance as to the development or liquidity of any market for the
Debentures. The Company does not intend to apply for listing of the Debentures

                                  THE COMPANY
 
  The Company is one of the largest operators of cable television systems in
the United States, with approximately 2,752,000 subscribers in 19 states as of
March 31, 1996 based on the number of basic subscribers in systems which the
Company manages and which it owns or in which it has investments. The Company
also has ownership interests in companies that produce and distribute national
and regional programming services and provide advertising sales services for
the cable television industry.
 
  For financing purposes, the Company is structured as a restricted group
(collectively, the "Restricted Group"), including Cablevision of NYC and, as
of December 15, 1995, a subsidiary holding the cable television assets
previously a part of Cablevision of Boston, and an unrestricted group of
subsidiaries. The unrestricted group of subsidiaries consists primarily of
Cablevision of Ohio (as defined under "Recent Developments-- V Cable
Transactions"), Cablevision MFR, Inc. ("Cablevision MFR" and, collectively
with Cablevision of Ohio, "Unrestricted Cable") and Rainbow Programming
Holdings, Inc. (including Rainbow Advertising Sales Corporation ("Rainbow
Advertising"), American Movie Classics Company ("AMCC") and SportsChannel
Associates ("SportsChannel New York"), collectively, "Rainbow Programming").
In addition, the Company has an unrestricted group of investments, consisting
of investments in A-R Cable Services, Inc. ("A-R Cable"), U.S. Cable
Television Group, L.P. ("U.S. Cable"), Cablevision of Framingham Holdings,
Inc. ("CFHI"), A-R Cable Partners and Cablevision of Newark. The Company's
unrestricted subsidiaries and investments are collectively referred to herein
as the "Unrestricted Group". See "Recent Developments" for a discussion of
certain transactions involving members of the Unrestricted Group, including
Cablevision of Ohio, A-R Cable, CFHI, A-R Cable Partners and Cablevision of
Newark. The Restricted Group and each member of the Unrestricted Group that
operates cable television systems are individually and separately financed.
The indebtedness of Cablevision of Ohio and A-R Cable is non-recourse to the
Company, other than with respect to the capital stock of such entities owned
by the Company. Rainbow Programming's cash requirements have been financed to
date by the Restricted Group, by sales of equity interests in the programming
businesses and, as set forth below under "--Programming Services", through
separate external debt financing. Rainbow Programming's future cash
requirements may be financed with separate external debt financing, which, as
to the assets of Rainbow Programming, would be structurally senior to any of
the Company's indebtedness. See "Management's Discussion and Analysis--
Liquidity and Capital Resources" for a discussion of the restrictions on
investments by the Restricted Group and certain other matters.
 
STRATEGY
 
  The Company's strategy has been to concentrate its cable television systems
in and around three major metropolitan areas, New York City, Boston and
Cleveland, with a view to being a significant cable provider in each of these
markets; to maximize its revenue per subscriber by marketing premium services;
to develop and promote niche programming services; and to remain an industry
leader in upgrading the technological capabilities of its systems.
 
  The Company believes that its cable television systems on Long Island, New
York comprise the largest contiguous group of cable television systems under
common ownership in the United States (measured by number of subscribers). By
developing systems in and around major metropolitan areas, including expansion
through acquisitions in areas in which the Company has existing systems, the
Company has been able to realize economies of scale in the operation and
management of its systems, and capitalize on opportunities to create and
market programming of regional interest.
 
  Through the current and planned upgrade of its cable plant, including the
utilization of fiber optic cable and associated electronics, the Company is
seeking to significantly increase its analog channel capacity and add new
digital channel capacity that will facilitate the startup of such adjunct
businesses as information services, interactive services (including Internet
access), near video on demand, video on demand, residential telephony and
commercial telephony. To successfully roll out these adjunct new businesses
significantly beyond the initial development phases, the Company will require
additional capital from the sale of equity in the capital markets or to a
strategic investor.

CABLE TELEVISION
 
  The cable television systems that are majority owned and managed by the
Company (the "Company's cable television systems") served approximately
2,085,000 subscribers as of March 31, 1996 in New York, Ohio, Connecticut, New
Jersey, Michigan and Massachusetts. In addition, the Company has non-majority
investments in and manages cable television systems which served approximately
667,000 subscribers as of March 31, 1996 in Alabama, Arkansas, Florida,
Illinois, Kansas, Kentucky, Maine, Massachusetts, Mississippi, Missouri, New
Jersey, New York, North Carolina, Oklahoma, Pennsylvania and Tennessee. The
Company's cable television systems have generally been characterized by
relatively high revenues per subscriber ($37.28 for March 1996) and ratios of
premium service units to basic subscribers (1.8:1 for March 1996). In
calculating revenue per subscriber, the Company includes only recurring
service revenues and excludes installation charges and certain other revenues
such as advertising, pay-per-view and home shopping revenues.
 
  The cable television operations in the Restricted Group served approximately
1,534,000 subscribers as of March 31, 1996, primarily on Long Island, New
York, in Connecticut (principally Fairfield County), in northern New Jersey,
in Westchester County, New York, in and around Boston, Massachusetts and in
Cleveland, Ohio. See "Recent Developments--V Cable Transactions" for a
discussion of the transactions pursuant to which the Company's cable
television systems in Cleveland, Ohio were contributed to Cablevision of Ohio
(a part of Unrestricted Cable) on April 17, 1996. The revenue per subscriber
and ratio of premium service units to basic subscribers for cable television
systems in the Restricted Group for March 1996 were $38.92 and 2.1:1,
respectively.
 
  The cable television operations in Unrestricted Cable served approximately
551,000 subscribers as of March 31, 1996 and are conducted through the
Company's unrestricted subsidiaries, Cablevision of Ohio and Cablevision MFR.
The Unrestricted Group also conducts its cable television operations through
its unrestricted investments, consisting of A-R Cable, U.S. Cable, CFHI, A-R
Cable Partners and Cablevision of Newark. The revenue per subscriber and ratio
of premium service units to basic subscribers for the Company's unrestricted
subsidiaries for March 1996 were $32.74 and 1.0:1, respectively. See "Recent
Developments--Pending Warburg Transactions" for a discussion of the Company's
agreement to acquire the remaining interests in A-R Cable, A-R Cable Partners,
Cablevision of Newark and CFHI (collectively, the "Warburg Companies") and
"Recent Developments--V Cable Transactions" for a discussion of the
transactions pursuant to which U.S. Cable will become part of Unrestricted
Cable.
 
  In August 1994, Cablevision MFR, a wholly-owned subsidiary of the Company,
acquired substantially all of the assets of Monmouth Cablevision Associates
("Monmouth Cable") and Riverview Cablevision Associates, L.P. ("Riverview
Cable"), consisting of cable television systems in New Jersey. Also in August
1994, CFHI, a corporation jointly owned by the Company and E.M. Warburg Pincus
Investors, L.P., acquired substantially all of the assets of Framingham
Cablevision Associates Limited Partnership ("Framingham Cable"), consisting of
a cable television system in Massachusetts. Additionally, in June 1994, a
partnership comprised of subsidiaries of the Company and E.M. Warburg, Pincus
& Co. Inc. completed the purchase of certain assets of Nashoba Communications,
a group of three limited partnerships that operate three cable television
systems in Massachusetts.
 
  See "Recent Developments--V Cable Transactions" in this Prospectus
Supplement and "Business--Recent Developments--V Cable Transactions" in the
Form 10-K for a description of the reorganization and recapitalization of V
Cable. This transaction resulted in the inclusion within the Restricted Group
of V Cable's Long Island cable television systems (which served approximately
161,000 subscribers as of March 31, 1996) and the transfer of the North Coast
Cable cable television systems (which served approximately 87,000 subscribers
as of March 31, 1996) from the Restricted Group to Unrestricted Cable and will
result in the acquisition of the 80% of U.S. Cable (which served approximately
245,000 subscribers as of March 31, 1996) not owned by the Company. U.S. Cable
will be part of Unrestricted Cable.

PROGRAMMING SERVICES
 
  The Company conducts its programming activities through Rainbow Programming,
its wholly-owned subsidiary and member of the Unrestricted Group, and through
subsidiaries of Rainbow Programming in partnership with certain unaffiliated
entities, including National Broadcasting Company, Inc. and Liberty Media
Corporation. Rainbow Programming's businesses include eight regional
SportsChannel services, four national entertainment services (American Movie
Classics ("AMC"), Bravo, MuchMusic ("MM") and the Independent Film Channel
("IFC")), Rainbow News 12 (regional news services serving suburban areas
surrounding New York City) and the sports services of Prime SportsChannel
Networks (Prime Network and NewSport). Rainbow Programming also owns an
interest in MSG Holdings (discussed below). Rainbow Programming's
SportsChannel services provide regional sports programming to the New York,
Philadelphia, New England, Chicago, Cincinnati, Cleveland, San Francisco and
Florida areas. AMC is a national program service featuring classic, unedited
and non-colorized films from the 1930s through the 1970s. Bravo is a national
program service offering international films and performing arts programs,
including jazz, dance, classical music, opera and theatrical programs. See
"Business--Programming Operations--General" in the Form 10-K. MM is a Canadian
music service featuring music primarily from Canadian artists. IFC is a
national program service that airs independent films made outside the
traditional Hollywood system.
 
  In March 1995, MSG Holdings, a partnership among subsidiaries of Rainbow
Programming and subsidiaries of ITT, acquired the business and assets of
Madison Square Garden ("MSG") in a transaction in which MSG merged with and
into MSG Holdings. MSG Holdings owns the Madison Square Garden Arena and the
adjoining Paramount Theater, the New York Rangers professional hockey team,
the New York Knickerbockers professional basketball team and the Madison
Square Garden Network, a sports programming network with over five million
subscribers. The purchase price paid by MSG Holdings for MSG was $1,009.1
million.
 
  MSG Holdings funded the purchase price of the acquisition through (i)
borrowings of $289.1 million under a $450 million credit agreement among MSG
Holdings, various lending institutions and Chemical Bank, as administrative
agent, (ii) an equity contribution from Rainbow Programming of $110 million,
and (iii) an equity contribution from ITT of $610 million. ITT, Rainbow
Programming and the Company are parties to an agreement made as of August 15,
1994 (as amended, the "Bid Agreement") that, as amended, provides Rainbow
Programming the right to acquire interests in MSG Holdings from ITT sufficient
to equalize the interests of ITT and Rainbow Programming in MSG Holdings by
making certain scheduled payments totalling $250 million (plus interest on any
unpaid portion thereof) on specified dates commencing October 1996 and up to
and including March 17, 1997. Rainbow Programming may acquire all or part of
such interests in MSG Holdings through (i) the payment of cash to ITT, (ii)
the delivery to ITT, at the option of the Company, of common or preferred
stock of the Company (together with the commitment of a nationally recognized
underwriter to promptly purchase such common or preferred stock for cash), or
a combination of cash and common or preferred stock (with such a commitment),
or (iii) the delivery to ITT, at the option of ITT, subject to certain
conditions and in lieu of payment of a limited amount of the required cash or
common or preferred stock for the purchase of a portion of such interests, of
certain designated programming interests of Rainbow Programming. If any
scheduled payment is not made on the applicable due date, then Rainbow
Programming will forfeit (a) its right to equalize the interests in MSG
Holdings and (b) certain minority rights. The Company and Rainbow Programming
may fund the interest payments on the unpaid portion of the $250 million
amount required to equalize the interests of ITT and Rainbow Programming in
MSG Holdings from available cash balances, from borrowings by Rainbow
Programming or from funds available under the Company's Credit Agreement.
Accordingly, the Company funded a $29 million interest payment on March 11,
1996 and the $2.2 million and $1.8 million monthly interest payments on April
15, 1996 and May 15, 1996, respectively, from funds available under the Credit
Agreement. If certain conditions are met and Rainbow Programming has forfeited
its right to equalize the interests in MSG Holdings, then Rainbow Programming
will also have the right to require ITT to purchase all of Rainbow
Programming's interest in MSG Holdings for an amount equal to (i) the price
paid by Rainbow Programming for such interest plus (ii) all interest paid by
Rainbow Programming on the unpaid portion of the $250 million of scheduled
payments (as described above).
 
 
                                     S-17
<PAGE>
 
  MSG Holdings is being managed on a 50-50 basis by Rainbow Programming and
ITT. If, as discussed above, Rainbow Programming does not equalize the
interests in MSG Holdings, its management role will be effectively eliminated.
Rainbow Programming also has the right to voluntarily relinquish any power to
direct the management and policies of MSG Holdings. In connection with
obtaining the consent of the National Hockey League (the "NHL") and the
National Basketball Association (the "NBA") to the indirect transfers of the
New York Rangers and the New York Knickerbockers, respectively, resulting from
the merger, the Company and Rainbow Programming entered into agreements with
the NHL and the NBA agreeing, among other matters, to conduct themselves in
accordance with the relevant rules of each league.
 
ADVERTISING SERVICES
 
  Rainbow Advertising sells advertising time to national, regional and local
advertisers on behalf of the Company's cable television systems and the
SportsChannel and Rainbow News 12 Company programming services, as well as on
behalf of unaffiliated cable television systems.
 
                              RECENT DEVELOPMENTS
 
PENDING WARBURG TRANSACTIONS
 
  On May 10, 1996, the Company entered into an agreement (the "Warburg
Agreement") with Warburg, Pincus Investors, L.P. ("Warburg") to acquire from
Warburg the interests that the Company does not already own in A-R Cable, A-R
Cable Partners, Cablevision of Newark and CFHI (collectively, the "Warburg
Companies") for an aggregate purchase price of $183 million (the "Pending
Warburg Transactions"). See "Business--Other Cable Affiliates" in the Form 10-
K for a description of these affiliates. The transaction is subject to the
receipt of necessary regulatory approvals.
 
  Under the Warburg Agreement, interests in each Warburg Company will be
purchased by the Company separately as the regulatory approvals related to the
purchase of such Warburg Company are received. With respect to any interest in
a Warburg Company that is not acquired by October 10, 1996, the allocated
purchase price for each such interest will be increased from and after October
10, 1996 by an interest factor of 8% per annum, compounded quarterly, until
the earlier of such date as the Company acquires the interests in such Warburg
Company or February 10, 1997. If any such purchases occur prior to October 10,
1996, the purchase price for the relevant interests will be reduced by the
same interest factor. If by February 10, 1997, all conditions to the Company's
purchase of Warburg's interest in any one of the Warburg Companies (other than
the receipt of regulatory approvals and third party consents) have been
satisfied but the acquisition of such interests has not occurred, the Company
will make a loan to Warburg in respect of each such Warburg Company, secured
by a pledge of such interests, in the amount of the allocated purchase price
therefor, plus the accrued interest resulting from the interest factor
adjustment discussed above. If the Company does not make the required loan,
Warburg will have the right to commence a sale process with respect to such
Warburg Company and will have a preferential right to receive its purchase
price from the proceeds of any such sale.
 
  The Pending Warburg Transactions will result in the Company increasing the
number of subscribers in cable television systems that are majority owned and
managed by the Company by approximately 422,000 subscribers to approximately
2,507,000 subscribers (as of March 31, 1996) and decreasing the number of
subscribers in cable television systems in which the Company has non-majority
investments by the same amount to approximately 245,000 subscribers (as of
March 31, 1996). See "Condensed Pro Forma Consolidated Financial Information".
The funds to purchase Warburg's interests are expected to be provided by bank
borrowings by the Company. See "Use of Proceeds".
 
  The Company intends to designate Cablevision of Newark (which served
approximately 48,000 subscribers as of March 31, 1996) as a member of the
Restricted Group and intends to make A-R Cable, A-R Cable Partners and CFHI a
part of Unrestricted Cable.
 
V CABLE TRANSACTIONS
 
  GECC Agreement. On February 2, 1996, the Company entered into an agreement,
as amended (the "GECC Agreement"), with General Electric Capital Corporation
("GECC"), pursuant to which the Company
 
                                     S-18
<PAGE>
 
effected a reorganization and recapitalization relating to V Cable. As of
March 31, 1996, V Cable served approximately 379,000 subscribers, principally
in the suburbs of Cleveland, Ohio and on Long Island. As part of this
reorganization and recapitalization, (i) on March 18, 1996, the Company repaid
$500 million of V Cable debt and $70 million of U.S. Cable debt, together with
accrued interest, from the proceeds of the Company's issuance in February 1996
of $650 million aggregate liquidation preference of the Series L Preferred
Stock; and (ii) on April 17, 1996, three subsidiaries in the Company's
Unrestricted Group, Telerama, Inc., Cablevision of the Midwest, Inc. and
Cablevision of Cleveland, L.P. (collectively, "Cablevision of Ohio"), borrowed
approximately $288.6 million under a new $500 million Cablevision of Ohio
credit facility and used such amounts to (a) repay approximately $209.0
million due under the credit facilities of V Cable and VC Holding, Inc. ("VC
Holding"), (b) repay approximately $75.0 million under the Company's Credit
Agreement in exchange for the Company's contribution of its North Coast Cable
cable television system (which served approximately 87,000 subscribers in the
Cleveland metropolitan area as of March 31, 1996) to Cablevision of Ohio (a
newly organized Unrestricted Subsidiary), and (c) repay approximately $4.6
million of fees and expenses in connection with the transactions. Also, on
April 17, 1996, the Company repaid approximately $215.0 million of remaining
indebtedness under V Cable's credit agreement (representing indebtedness
associated with V Cable's Long Island systems) with borrowings under the
Credit Agreement and designated the Long Island systems (which served
approximately 161,000 subscribers as of March 31, 1996) previously within V
Cable as part of the Restricted Group. As a result of these transactions, the
V Cable and VC Holding credit agreements were repaid in full and terminated.
In connection with the GECC Agreement, the 80% interest in U.S. Cable (which
served approximately 245,000 subscribers as of March 31, 1996), including U.S.
Cable's 19% interest in VC Holding not owned by V Cable, will be acquired for
approximately $4 million and V Cable will repay approximately $152 million to
GECC, which will be raised through a separate bank facility (U.S. Cable will
be part of Unrestricted Cable).
 
  New Cablevision of Ohio Credit Facility. As part of the V Cable
reorganization and recapitalization, the Company combined its North Coast
Cable cable television system and the Ohio cable television systems of V Cable
into Cablevision of Ohio, which is a wholly-owned subsidiary of the Company
and a member of the Unrestricted Group. A group of banks has provided the $500
million Cablevision of Ohio credit facility, consisting of a $425 million
nine-year reducing revolving credit facility and a $75 million 9 1/2 year term
loan. As discussed above, in connection with the consummation of the
reorganization and recapitalization of V Cable, Cablevision of Ohio drew
approximately $288.6 million under its credit facility to repay outstanding V
Cable debt to GECC and to repay Restricted Group debt assumed by Cablevision
of Ohio in connection with the contribution of North Coast Cable.
 
  U.S. Cable Acquisition. On March 18, 1996, the Company contributed $70
million of proceeds of the Series L Preferred Stock offering mentioned above
to U.S. Cable. U.S. Cable applied the $70 million to the prepayment to GECC of
a portion of the indebtedness under its credit facility. The GECC Agreement
contemplates that following the receipt of any required franchise and
regulatory approvals, U.S. Cable will (i) redeem the 80% of U.S. Cable's
partnership interests not owned by V Cable for approximately $4 million and
(ii) refinance the remaining $152 million of U.S. Cable indebtedness payable
to GECC. The funds to redeem the partnership interest and to repay
indebtedness owed to GECC will be provided by a drawdown under a $175 million
credit facility to be arranged with a new group of banks. As part of the
acquisition of the 80% interest in U.S. Cable that V Cable does not already
own, the Company will acquire the 19% interest in VC Holding currently held by
U.S. Cable.
 
  There can be no assurance that the acquisition of the U.S. Cable partnership
interests will be consummated or will be consummated in the form presently
contemplated.

                                USE OF PROCEEDS
 
  The net proceeds to be received by the Company from the Offering are
estimated to be $243.2 million. The Company will initially apply the net
proceeds from the Offering to the repayment of borrowings under the Company's
Credit Agreement. All of the borrowings repaid may be reborrowed under the
Credit Agreement, and the Company expects to reborrow such amount in the
future in connection with the Pending Warburg Transactions and for general
corporate purposes. The Company also expects to raise additional funds in the
future. See "Management's Discussion and Analysis--Liquidity and Capital
Resources" for information concerning the Company's significant expected
expenditures.
 
  The borrowings under the Credit Agreement being repaid bear interest at
floating rates, currently 7.9%, and mature in installments over the 1996-2003
time period. See "Management's Discussion and Analysis--Liquidity and Capital
Resources".
 
  Concurrently with the Offering, the Company is offering (the "Other
Offering") its $150,000,000 of 9 7/8% Senior Subordinated Notes due 2006 (the
"Notes"). The Company expects to use the net proceeds from the Other Offering
(estimated to be $145.4 million) to repay borrowings under the Credit
Agreement. The Company expects to reborrow the amount repaid under the Credit
Agreement in the future in connection with the Pending Warburg Transactions
and for general corporate purposes. The consummation of the Other Offering is
not a condition to the consummation of this Offering, nor is the consummation
of this Offering a condition to the consummation of the Other Offering.

FOOTNOTES
 
(1) See "Management's Discussion and Analysis--Liquidity and Capital
    Resources" and the Consolidated Financial Statements for a description of
    the bank indebtedness. These amounts do not include approximately $17.2
    million reserved under the Company's bank credit agreements for certain
    letters of credit issued on behalf of the Company. The Company and its New
    Jersey subsidiary are jointly and severally liable under the New Jersey
    subsidiary's credit agreement.
(2) Represents Cablevision MFR, Inc. seller notes in the amount of $141.3
    million for Monmouth Cable and Riverview Cable and $9.7 million for
    Framingham Cable (after giving effect to the Pending Warburg
    Transactions). These amounts are guaranteed by the Restricted Group.
(3) Obligation of NYC LP Corp., a wholly-owned Unrestricted Group subsidiary,
    relating to the acquisition of Cablevision of NYC, which obligation has
    been guaranteed by the Company. The Company's obligation under such
    guarantee may be paid in cash or, at the Company's option, shares of the
    Company's Common Stock. Under the Credit Agreement, the Company is
    currently prohibited from paying all but $40.0 million of this obligation
    in cash and, accordingly, without the consent of the Company's bank
    lenders, would be required to pay it in shares of the Company's Common
    Stock.
(4) Represents the cancellation of 1,091,553 shares of treasury stock of which
    1,041,553 shares were issued to a wholly-owned subsidiary of the Company
    in connection with the Company's acquisition of Cablevision of Boston.

     Offering not being applied to the Pending Warburg Transactions
     ($183,000,000) and expenses/note discount ($11,428,000) of this Offering

                         DESCRIPTION OF THE DEBENTURES
 
  The following description of the particular terms of the Debentures
supplements and, to the extent inconsistent therewith, supersedes the
description of the general terms of the Debt Securities set forth under the
heading "Description of Debt Securities" in the accompanying Prospectus, to
which description reference is made.
 
  The Debentures will be issued under an Indenture dated as of November 1,
1995 (the "Indenture"), between the Company and The Bank of New York, as
trustee (the "Trustee"). The Indenture is subject to and is governed by the
Trust Indenture Act of 1939, as amended. The following summaries of certain
provisions of the Indenture do not purport to be complete, and where reference
is made to particular provisions of the Indenture, such provisions, including
the definitions of certain terms, are incorporated by reference as a part of
such summaries or terms, which are qualified in their entirety by such
reference. The definitions of certain capitalized terms used in the Indenture
and in the following summary are set forth below under "Description of Debt
Securities--Certain Definitions" in the accompanying Prospectus.
 
GENERAL
 
  The Debentures are limited to $250,000,000 aggregate principal amount and
will be issued in fully registered form, without coupons, in denominations of
$1,000 and integral multiples thereof. The Debentures will mature on May 15,
2016.
 
  The Debentures will bear interest from May 21, 1996 at a rate of 10 1/2% per
annum, payable semi-annually on May 15 and November 15 of each year,
commencing November 15, 1996. Interest on the Debentures will be computed on
the basis of a 360-day year of twelve 30-day months and is payable to the
person in whose name each Debenture was registered at the close of business on
the preceding May 1 and November 1, respectively, subject to certain
exceptions. The Debentures will be unsecured obligations of the Company. The
Debentures will be subordinated to all existing and future Senior Indebtedness
of the Company.
 
  Principal of and premium, if any, and interest on the Debentures will be
payable, and the Debentures will be exchangeable and transferable, at the
office or agency of the Company in The City of New York (which initially will
be the Corporate Trust Office of the Trustee); provided, however, that payment
of interest, to the extent paid in cash, may be made at the option of the
Company by check mailed to the person entitled thereto as shown on the
Register of the Debentures. No service charge will be made for any
registration of transfer or exchange of Debentures, except for any tax or
other governmental charge that may be imposed in connection therewith.
 
  The Indenture does not contain any provisions that limit the ability of the
Company to incur indebtedness or that afford Holders of the Debentures
protection in the event of a highly leveraged or similar transaction involving
the Company, other than as described under "Description of Debt Securities--
Certain Covenants of the Company--Limitation on Indebtedness" in the
accompanying Prospectus.
 
SINKING FUND
 
  The Debentures will not be entitled to the benefits of a sinking fund.
 
OPTIONAL REDEMPTION
 
  The Debentures will be subject to redemption at any time on or after May 15,
2006, at the option of the Company, in whole or in part, on not less than 30
nor more than 60 days' prior notice at the following redemption prices
(expressed as percentages of the principal amount), if redeemed during the 12-
month period beginning May 15 of the years indicated:

and thereafter at 100% of the aggregate principal amount, in each case
together with accrued interest to the redemption date (subject to the right of
Holders of record on relevant record dates to receive interest due on an
interest payment date). If less than all of the Debentures are to be redeemed,
the Trustee shall select the Debentures or portions thereof to be redeemed
either pro rata or by lot.
 
  The Credit Agreement currently prohibits the Company from making optional
redemptions of the Debentures other than through the issuance of subordinated
indebtedness, preferred stock or common stock.
 
SUBORDINATION
 
  The indebtedness represented by the Debentures will be subordinated in right
of payment to the prior payment in full of all Senior Indebtedness.
 
  Upon the maturity of any Senior Indebtedness, by lapse of time, acceleration
or otherwise, or upon any payment default (with or without the giving of
notice or lapse of time or both in accordance with the terms of the instrument
governing such Senior Indebtedness, and without any waiver or forgiveness)
with respect to any Senior Indebtedness, all obligations with respect to such
Senior Indebtedness must first be paid in full, or such payment duly provided
for, before any payment is made with respect to the Debentures or before any
acquisition of Debentures by the Company.
 
  Upon (i) a default with respect to any Senior Indebtedness (other than under
circumstances when the terms of the previous paragraph are applicable), as
such default is defined therein or in the instrument under which it is
outstanding, permitting the holders of Senior Indebtedness to accelerate the
maturity thereof, and (ii) written notice thereof ("Default Notice") given to
the Company and the Trustee by the agent or agents under the Credit Agreement,
then, unless and until such default shall have been cured or waived by the
holders of such Senior Indebtedness or shall have ceased to exist, no direct
or indirect payment may be made by the Company with respect to the principal
of, premium, if any, or interest on the Debentures (other than payments made
in Junior Securities) or to acquire any of the Debentures or on account of the
redemption provisions of the Debentures (except mandatory redemption payments
made, in accordance with the terms of the Debentures, in Debentures acquired
by the Company before the Default Notice); provided, however, that such
provision shall not prevent the making of any payment (which is not otherwise
prohibited by the previous paragraph) for more than 120 days after the Default
Notice shall have been given unless the Senior Indebtedness in respect of
which such event of default exists has been declared due and payable in its
entirety, in which case no such payment may be made until such acceleration
has been rescinded or annulled or such Senior Indebtedness has been paid in
full. Notwithstanding the foregoing, not more than one Default Notice may be
given with respect to Senior Indebtedness within a period of 240 consecutive
days.
 
  The Indenture provides that, upon any payment by or distribution of the
assets of the Company to creditors upon any dissolution, winding up,
liquidation, bankruptcy, reorganization, assignment for the benefit of
creditors, or any insolvency, receivership or similar proceeding relating to
the Company, all Senior Indebtedness must be paid in full, or such payment
duly provided for, before any payment or distribution (other than in Junior
Securities) is made on account of the principal of or premium, if any, or
interest on the Debentures.
 
  By reason of such subordination, in the event of liquidation or insolvency,
creditors of the Company who are holders of Senior Indebtedness may recover
more, ratably, than other creditors of the Company, and creditors of the
Company who are not holders of Senior Indebtedness or of the Debentures (or
the Company's 10 3/4% Senior Subordinated Debentures due 2004, the Company's 9
7/8% Senior Subordinated Debentures due 2013, the Company's 9 7/8% Senior
Subordinated Debentures due 2023, the Company's 9 1/4% Senior Subordinated
Notes due 2005 (collectively, the "Existing Debentures") and the Notes) may
recover more, ratably, than the Holders of the Debentures.
 
  A Holder of Debentures by his acceptance of Debentures agrees to be bound by
such provisions and authorizes and expressly directs the Trustee, on his
behalf, to take such action as may be necessary or appropriate to effectuate
the subordination provided for in the Indenture and appoints the Trustee his
attorney-in-fact for such purpose.

  The amount of Senior Indebtedness outstanding at March 31, 1996, adjusted to
give pro forma effect to the transactions described under "Capitalization" and
the application of the net proceeds to the Company from this Offering and the
Other Offering, would have been approximately $569.4 million.
 
CERTAIN COVENANTS OF THE COMPANY
 
  Limitation on Indebtedness. The Indenture provides that the Company shall
not, and shall not permit any Restricted Subsidiary to, directly or indirectly
incur, create, issue, assume, guarantee or otherwise become liable for,
contingently or otherwise, or become responsible for the payment of,
contingently or otherwise, any Indebtedness (other than Indebtedness between
or among any of the Company and Restricted Subsidiaries) unless, after giving
effect thereto, the Cash Flow Ratio shall be less than or equal to 9 to 1. At
March 31, 1996, such Cash Flow Ratio was approximately 5.7 to 1.
 
  Limitation on Senior Subordinated Indebtedness. The Indenture provides that
the Company shall not, and shall not permit any Restricted Subsidiary to,
directly or indirectly, create, incur, issue, assume, guarantee or otherwise
become liable for, contingently or otherwise, or become responsible for the
payment of, contingently or otherwise, any Indebtedness which is both (i)
senior in right of payment to the Debentures and (ii) expressly subordinate in
right of payment to any other Indebtedness of the Company. For purposes of
this covenant, Indebtedness is deemed to be senior in right of payment of the
Debentures if it is not subordinate in right of payment to Senior Indebtedness
at least to the same extent as the Debentures are subordinate to Senior
Indebtedness.
 
  Limitation on Restricted Payments. The Indenture provides that, so long as
any of the Debentures remain outstanding, the Company will not, and will not
permit any Restricted Subsidiary to, make any Restricted Payment if (a) at the
time of such proposed Restricted Payment, a Default or Event of Default shall
have occurred and be continuing or shall occur as a consequence of such
Restricted Payment or (b) immediately after giving effect to such Restricted
Payment, the aggregate of all Restricted Payments that shall have been made on
or after July 1, 1988 would exceed the sum of:
 
    (i) $25,000,000, plus
 
    (ii) an amount equal to the difference between (A) the Cumulative Cash
  Flow Credit and (B) 1.2 multiplied by Cumulative Interest Expense.
 
  Notwithstanding the foregoing, so long as no Default or Event of Default
shall have occurred and be continuing, the Company may make any Permitted
Restricted Payment; provided, however, that such Permitted Restricted Payment
shall thereafter be counted as a Restricted Payment solely for purposes of
calculating whether any future Restricted Payments are permitted under clause
(b) of the preceding sentence.
 
  For purposes of the "Limitation on Restricted Payments" covenant, the amount
of any Restricted Payment or Permitted Restricted Payment, if other than cash,
shall be based upon fair market value as determined by the Board of Directors
of the Company, whose good faith determination shall be conclusive.
 
  The foregoing provisions do not prevent: (i) the payment of any dividend
within 60 days after the date of declaration thereof, if at such date of
declaration such payment complied with the above provisions; (ii) the
retirement or redemption of any shares of the Company's capital stock or
warrants, rights or options to acquire capital stock of the Company, in
exchange for, or out of the proceeds of a substantially concurrent sale of,
other shares of the Company's capital stock or warrants, rights or options to
acquire capital stock of the Company (other than Disqualified Stock); and
(iii) the redemption of or payments of cash dividends on the Company's 8%
Series C Cumulative Preferred Stock (the "Series C Preferred Stock")
outstanding on January 1, 1995, which redemptions or dividends are provided
for by the terms of the Series C Preferred Stock in effect on such date (or
redemption of or payment of cash dividends on any security of the Company
issued in exchange for or upon the conversion of such Series C Preferred
Stock; provided that the aggregate amount payable pursuant to the terms of
such security is no greater than the aggregate amount payable pursuant to the
terms of the Series C Preferred
 
                                     S-32

Stock). For purposes of determining the aggregate permissible amount of
Restricted Payments in accordance with clause (b) of the first paragraph of
this covenant, all amounts expended pursuant to clauses (i) and (iii) of this
paragraph shall be included and all amounts expended or received pursuant to
clause (ii) of this paragraph shall be excluded; provided, however, that
amounts paid pursuant to clause (i) of this paragraph shall be included only
to the extent that such amounts were not previously included in calculating
Restricted Payments.
 
  For the purposes of the foregoing provisions, the net proceeds from the
issuance of shares of capital stock of the Company upon conversion of
Indebtedness shall be deemed to be an amount equal to (i) the accreted value
of such Indebtedness on the date of such conversion and (ii) the additional
consideration, if any, received by the Company upon such conversion thereof,
less any cash payment on account of fractional shares (such consideration, if
in property other than cash, to be determined by the Board of Directors of the
Company whose good faith determination shall be conclusive). If the Company
makes a Restricted Payment which, at the time of the making of such Restricted
Payment would in the good faith determination of the Company be permitted
under the requirements of this covenant, such Restricted Payment shall be
deemed to have been made in compliance with this covenant notwithstanding any
subsequent adjustments made in good faith to the Company's financial
statements affecting Cumulative Cash Flow Credit or Cumulative Interest
Expense for any period.
 
  As of March 31, 1996, the Company would have been permitted to make
Restricted Payments of $613.1 million.
 
  Limitation on Investments in Unrestricted Subsidiaries and Affiliates. The
Indenture provides that the Company will not, and will not permit any
Restricted Subsidiary to, directly or indirectly (i) make any Investment or
(ii) allow any Restricted Subsidiary to become an Unrestricted Subsidiary (a
"redesignation of a Restricted Subsidiary"), in each case unless (a) no
Default or Event of Default shall have occurred and be continuing or shall
occur as a consequence of such Investment or such redesignation of a
Restricted Subsidiary, and (b) after giving effect thereto, the Cash Flow
Ratio shall be less than or equal to 9 to 1.
 
  The foregoing provisions of this covenant shall not prohibit (i) any renewal
or reclassification of any Investment existing on the date hereof or (ii)
trade credit extended on usual and customary terms in the ordinary course of
business.
 
  Transactions with Affiliates. The Indenture provides that the Company shall
not, and shall not permit any of its subsidiaries to, sell, lease, transfer or
otherwise dispose of any of its properties or assets to or purchase any
property or assets from, or enter into any contract, agreement, understanding,
loan, advance or guarantee with, or for the benefit of, an Affiliate of the
Company that is not a subsidiary of the Company, having a value, or for
consideration having a value, in excess of $10,000,000 individually or in the
aggregate unless the Board of Directors of the Company shall make a good faith
determination that the terms of such transaction are, taken as a whole, no
less favorable to the Company or such subsidiary, as the case may be, than
those which might be available in a comparable transaction with an unrelated
Person. For purposes of clarification, this provision shall not apply to
Restricted Payments or Permitted Restricted Payments permitted under "--
Limitation on Restricted Payments".
 
REGARDING THE TRUSTEE
 
  The Bank of New York ("BONY") is the Trustee under the Indenture, which
relates to the Debentures and the Notes, and is the trustee under the
indentures relating to the Company's Existing Debentures. BONY is a party to
certain credit agreements with the Company and its subsidiaries, including the
Credit Agreement, borrowings under which constitute Senior Indebtedness under
the Indenture. BONY may also maintain other banking arrangements with the
Company in the ordinary course of business.

  The Underwriters have advised the Company that they propose initially to
offer the Debentures directly to the public at the public offering price set
forth on the cover page of this Prospectus Supplement, and to certain dealers
at such price less a concession not in excess of .25% of the principal amount
of the Debentures. The Underwriters may allow, and such dealers may reallow, a
discount not in excess of .125% of the principal amount of the Debentures to
certain other dealers. After the initial public offering, the public offering
price, concession and reallowance may be changed by the Underwriters.
 
  There is no public market for the Debentures. The Company does not intend to
list the Debentures on any securities exchange or to arrange for their
quotation on NASDAQ. The Company has been advised by the Underwriters that
they presently intend to make a market in the Debentures after the
consummation of the Offering, although they are under no obligation to do so.
No assurance can be given, however, as to the liquidity of the trading market
for the Debentures or that an active public market for the Debentures will
develop. If an active public market does not develop, the market prices and
liquidity of the Debentures may be adversely affected.
 
  Each of Bear, Stearns & Co. Inc. ("Bear Stearns") and Merrill Lynch, Pierce,
Fenner & Smith Incorporated ("Merrill Lynch") has from time to time provided
investment banking services to the Company (and in the case of Merrill Lynch,
Charles F. Dolan) in connection with various transactions and proposed
transactions. In addition, Bear Stearns, Merrill Lynch and Morgan Stanley &
Co. Incorporated were the initial purchasers in the offering of the Company's
Series G Preferred Stock in September 1995 and the Company's Series L
Preferred Stock in February 1996 and were underwriters of the Company's 9 1/4%
Senior Subordinated Notes due 2005 and the Company's Series I Preferred Stock
represented by Depositary Shares in November 1995.
 
  In connection with this Offering, the Company has agreed to indemnify the
Underwriters against certain liabilities, including liabilities under the
Securities Act of 1933, as amended.
 
                            VALIDITY OF DEBENTURES
 
  The validity of the Debentures will be passed upon for the Company by
Sullivan & Cromwell, New York, New York and for the Underwriters by Shearman &
Sterling, New York, New York.
