                                    SUMMARY
 
  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.
 
                                  THE COMPANY
 
  The Company is one of the largest operators of cable television systems in
the United States, with approximately 2,753,000 subscribers in 19 states as of
June 30, 1995 based on the number of basic subscribers in systems which the
Company manages and which it owns or in which it has investments (including
91,000 subscribers in the Cablevision of Chicago system that was sold on August
4, 1995, as discussed below). 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
1,866,000 subscribers as of June 30, 1995 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
887,000 subscribers as of June 30, 1995 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 ($37.14 for June 1995) and ratios of
premium service units to basic subscribers (1.7:1 for June 1995). 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.
 
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 Company, Bravo Network, MuchMusic and the Independent Film
Channel), Rainbow News 12 Company (a regional news service serving Long Island)
and the national backdrop sports services of Prime SportsChannel Networks.
Rainbow Programming also owns an interest in Madison Square Garden Corporation.
 
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 News 12 programming services, as well as on
behalf of unaffiliated cable television systems.
 
COMPANY'S THIRD QUARTER RESULTS
 
  The Company's net revenues for the three and nine months ended September 30,
1995 increased 24% and 33%, respectively, over the corresponding 1994 periods.
Increases of 12% and 21%, respectively, for the three
 
                                      S-3
<PAGE>
 
and nine month periods were attributable to acquisitions made during 1994 and
1995. The remaining increases of 12% in each period came primarily from
internal growth in the average number of subscribers (approximately 147,500
(10%) for the nine month 1995 period over the same 1994 period).
 
  Net losses for the three and nine months ended September 30, 1995 amounted to
$41.7 million and $237.1 million, or $1.85 and $10.29 per common share (after
preferred dividend requirements), as compared to net losses of $66.9 million
and $178.7 million, or $2.93 and $7.82 per common share (after preferred
dividend requirements), for the same periods in 1994. The increase in net loss
for the nine month 1995 period was primarily due to the net losses of companies
acquired during 1994. The decrease in net loss for the three month 1995 period
reflects gains related to the sale of one cable affiliate and interests in one
programming partnership aggregating approximately $36.2 million.

                               $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

                               amount of Senior Indebtedness outstanding at
                               June 30, 1995, 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 Notes and of the Company's  %
                               Series I Cumulative Convertible Exchangeable
                               Preferred Stock (the "Series I Preferred Stock")
                               represented by depositary shares (the
                               "Offerings"), would have been approximately
                               $563.6 million. At June 30, 1995, the Company
                               also had outstanding $955.1 million of senior
                               subordinated indebtedness and obligations
                               (including $331.5 million of indebtedness of
                               subsidiaries guaranteed by the Company, included
                               in indebtedness of consolidated subsidiaries set
                               forth in the next sentence) that would have
                               ranked pari passu with the Notes. Also, at June
                               30, 1995, consolidated subsidiaries of the
                               Company had outstanding, 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
                               Offerings, approximately $1,284.4 million of
                               indebtedness which, insofar as the assets of
                               those subsidiaries are concerned, would have
                               been effectively senior to the Notes.
 
Certain Restrictions........  The Indenture for the Notes will, among other
                               things, contain 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 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 Notes and expressly
                               subordinate in right of payment to any other
                               indebtedness of the Company.

Absence of Public Market....  There is no public market for these Notes. The
                               Company does not intend to apply for listing of
                               the Notes on any securities exchange or for
                               quotation through the National Association of
                               Securities Dealers Automated Quotation System.
                               Although Merrill Lynch & Co., Merrill Lynch,
                               Pierce, Fenner & Smith Incorporated, Bear,
                               Stearns & Co. Inc., Morgan Stanley & Co.
                               Incorporated and Toronto Dominion Securities
                               (USA) Inc. have informed the Company that they
                               currently intend to make a market in the Notes,
                               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 Notes.
 
Concurrent Offering.........  The Company is concurrently with the offering of
                               the Notes offering its depositary shares (the
                               "Depositary Shares") representing the Series I
                               Preferred Stock with an aggregate liquidation
                               preference of $300 million. The Company expects
                               to use the net proceeds from that offering
                               (estimated to be $289.3 million) to repay
                               borrowings under the Company's principal bank
                               credit agreement. The consummation of the
                               offering of the Depositary Shares is not a
                               condition to the consummation of the offering of
                               the Notes offered hereby, nor is the
                               consummation of the offering of the Notes a
                               condition to the offering of the Depositary
                               Shares.
 
 
Use of Proceeds.............  The net proceeds to be received by the Company
                               from the Offering of the Notes (estimated to be
                               $243.5 million) will initially be applied to
                               repay borrowings under the Company's principal
                               bank credit agreement. The Company expects to
                               raise additional funds in the future. See "Use
                               of Proceeds".

(1) The consolidated statement of operations, balance sheet and statistical
    data reflect (i) the deconsolidation of A-R Cable Services, Inc. ("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 Mr. 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 and 1990 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 V Cable Reorganization (as defined under "The
    Company--Cable Television"), the Company redeemed A-R Cable's redeemable
    preferred stock on May 11, 1992, incurring a loss of $20 million.
(5) In connection with the 1992 V Cable Reorganization, the Company wrote off
    approximately $7.5 million of deferred financing costs related to the debt
    of V Cable, Inc. 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
    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 (New
    York) Associates and Rainbow News 12 Company, 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.

                                  THE COMPANY
 
  The Company is one of the largest operators of cable television systems in
the United States, with approximately 2,753,000 subscribers in 19 states as of
June 30, 1995 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"), consisting of Cablevision Systems
Corporation and certain of its subsidiaries, including Cablevision of New York
City ("Cablevision of NYC"), and an unrestricted group of subsidiaries,
consisting primarily of V Cable, Inc. ("V Cable"), Cablevision MFR, Inc.
("Cablevision MFR") and Rainbow Programming Holdings, Inc., including Rainbow
Advertising Sales Corporation ("Rainbow Advertising") (together, "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 Holding, Inc. ("CFHI"), A-R Cable Partners, Cablevision of Boston
Limited Partnership ("Cablevision of Boston") and Cablevision of Newark. As
discussed below under "Risk Factors", the Cablevision of Chicago system, which
was managed by the Company and includes approximately 91,000 subscribers, was
sold in August 1995 and is no longer managed by the Company. The Company's
unrestricted subsidiaries and investments are collectively referred to herein
as the "Unrestricted Group". The Restricted Group and each member of the
Unrestricted Group that operates cable television systems are individually and
separately financed. The indebtedness of V Cable 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. 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 two major metropolitan areas, New York City and Cleveland, Ohio,
with a view to being the largest cable provider in each of these markets; to
maximize its revenue per subscriber through the use of "tiered" packaging
strategies for 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 development of such adjunct
new businesses as video on demand, near video on demand, information services,
interactive services, including Internet access, residential telephony and
commercial telephony. To implement successfully and roll out these adjunct new
businesses 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 televisions systems") served approximately
1,866,000 subscribers as of June 30, 1995 in New York, Ohio,
 
                                     S-12
<PAGE>
 
Connecticut, New Jersey, Michigan and Massachusetts. In addition, the Company
has non-majority investments in and manages cable television systems which
served approximately 887,000 subscribers as of June 30, 1995 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
($37.14 for June 1995) and ratios of premium service units to basic
subscribers (1.7:1 for June 1995). 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 (other than those of
Cablevision of NYC) (such operations, the "Core Restricted Group") served
approximately 950,000 subscribers as of June 30, 1995, primarily on Long
Island, New York, in Connecticut (principally Fairfield County), in northern
New Jersey, in Westchester County, New York and in Cleveland, Ohio. The
revenue per subscriber and ratio of premium service units to basic subscribers
for cable television systems in the Core Restricted Group for June 1995 were
$37.82 and 1.5:1, respectively.
 
  In July 1992, the Company acquired from Charles F. Dolan, the Company's
Chairman, substantially all of Cablevision of NYC (the "Cablevision of NYC
Acquisition"), a cable television system under development in The Bronx and in
parts of Brooklyn, New York. Prior to the acquisition, the Company had a 15%
interest in Cablevision of NYC. Mr. Dolan remains a partner in Cablevision of
NYC with a 1% interest and the right to certain preferential payments. See
"Business--Consolidated Cable Affiliates--Cablevision of New York City" in the
Form 10-K. As of June 30, 1995, Cablevision of NYC passed approximately
912,000 homes and served approximately 371,000 subscribers. Construction of
the systems in The Bronx and in Brooklyn has been substantially completed. The
Company expects that the remaining costs to complete the construction of the
Cablevision of NYC systems will be financed by cash flow generated from the
operations of Cablevision of NYC and the amounts available under the Company's
principal bank credit agreement (the "Credit Agreement"). See "Management's
Discussion and Analysis--Liquidity and Capital Resources--Cablevision of NYC".
 
  The cable television operations of the Unrestricted Group are conducted
through the Company's unrestricted subsidiaries, V Cable and Cablevision MFR,
through its unrestricted investments, consisting of A-R Cable, U.S. Cable,
CFHI, A-R Cable Partners, Cablevision of Boston, and Cablevision of Newark.
 
  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.
 
  V Cable was formed by the Company in February 1989 and served approximately
372,000 subscribers as of June 30, 1995, principally in the suburbs of
Cleveland, Ohio and on Long Island. The revenue per subscriber and ratio of
premium service units to basic subscribers for V Cable's systems for June 1995
were $31.10 and 1.0:1, respectively. As described under "Business--
Consolidated Cable Affiliates--V Cable" in the Form 10-K, the Company
consummated a significant restructuring and reorganization involving V Cable
and U.S. Cable (the "1992 V Cable Reorganization") on December 31, 1992. See
also "Recent Developments--Proposed V Cable Transactions" for a description of
certain transactions involving V 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
 
                                     S-13
<PAGE>
 
partnership with certain unaffiliated entities, including National
Broadcasting Company, Inc. ("NBC") and Liberty Media Corporation ("Liberty").
Rainbow Programming's businesses include eight regional SportsChannel
services, four national entertainment services (American Movie Classics
Company ("AMCC"), Bravo Network ("Bravo"), MuchMusic ("MM") and the
Independent Film Channel ("IFC")), Rainbow News 12 Company (a regional news
service serving Long Island) and the national backdrop sports services of
Prime SportsChannel Networks ("Prime SportsChannel"). Rainbow Programming also
owns an interest in Madison Square Garden Corporation (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. AMCC 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 July 1994, Rainbow Programming purchased Liberty's 50% interest in AMCC
for a purchase price of approximately $181.0 million pursuant to a buy-sell
procedure set forth in the Partnership Agreement of AMCC. In July 1995,
Rainbow Programming purchased NBC's interest in SportsChannel (New York)
Associates and Rainbow News 12 Company (the "NBC Option") for an aggregate
purchase price of approximately $95.5 million, and, effective as of such date,
consolidated the results of operations of SportsChannel (New York) Associates
and Rainbow News 12 Company with those of the Company. See "Recent
Developments--NBC Option" and "Business--Programming Services" in the 
Form 10-K.
 
  On March 10, 1995, MSG Holdings, L.P. ("MSG Holdings"), a partnership
between a subsidiary of Rainbow Programming and a subsidiary of ITT
Corporation ("ITT"), acquired Madison Square Garden Corporation ("MSG") in a
transaction in which MSG was merged with and into MSG Holdings. MSG owns the
Madison Square Garden Arena and the adjoining Paramount Theater, the New York
Rangers professional hockey team, the New York Knicks professional basketball
team and the Madison Square Garden Network, a sports programming network with
over five million subscribers. Rainbow Programming has the option until March
10, 1996 to (i) acquire interests in MSG Holdings from ITT sufficient to
equalize the interests of ITT and Rainbow Programming in MSG Holdings, (ii)
maintain its investment at the initial level, or (iii) require ITT to purchase
50% of Rainbow Programming's initial interest in MSG Holdings at the price
paid by Rainbow Programming for such interest plus an adjustment for Rainbow
Programming's share of MSG Holdings' operating income after interest expense,
if any, following the closing of the acquisition of MSG. Rainbow Programming
has not determined which alternative it will pursue. See "Business--
Programming Services" in the Form 10-K.

                              RECENT DEVELOPMENTS
 
PROPOSED V CABLE TRANSACTIONS
 
  The Company, V Cable and VC Holding, Inc. ("VC Holding") have entered into a
general, non-binding letter of intent with General Electric Capital
Corporation ("GECC"), the principal creditor of V Cable. In the transactions
proposed by the letter of intent, the Company would issue to GECC preferred
stock having an initial aggregate liquidation preference of $500 million for
an aggregate purchase price of $500 million. It is anticipated that such
preferred stock would be redeemable at the option of the Company and would be
convertible at the option of the holder at certain times and in certain
circumstances in whole or in part into Class A Common Stock
 
                                     S-14
<PAGE>
 
at a conversion rate based upon the trading value of the Class A Common Stock
at the time of such conversion. The Company would make an equity capital
contribution to V Cable of the gross proceeds from such issuance and V Cable
would apply such amounts as set forth below.
 
  As part of the proposed transactions contemplated by the letter of intent
(together with the issuance of the preferred stock to GECC, the "Proposed V
Cable Transactions"), the $500 million capital contribution received by V
Cable would be applied as follows: (i) approximately $26 million to repay V
Cable's outstanding indebtedness to GECC; (ii) approximately $93 million to
repay to GECC a portion of U.S. Cable's debt payable by V Cable under certain
circumstances; (iii) approximately $331 million to repay to GECC a portion of
VC Holding's indebtedness; and (iv) $50 million would be used by VC Holding to
make a preferred capital contribution to U.S. Cable as discussed below. The
Company's $500 million capital contribution to V Cable has received the
requisite approval of a majority of the Company's banks under the Credit
Agreement.
 
  The Proposed V Cable Transactions also contemplate that V Cable will enter
into one or more agreements pursuant to which, following the receipt of any
required franchise and regulatory approvals, V Cable or one or more of its
subsidiaries (i) will purchase the 80% of U.S. Cable that V Cable does not
already own for approximately $4 million, (ii) will make a preferred capital
contribution to U.S. Cable of $50 million, and (iii) will assume approximately
$165 million of U.S. Cable indebtedness payable to GECC.
 
  As part of the Proposed V Cable Transactions, GECC would also agree to
provide two new credit facilities, a $325 million three year revolving credit
facility for V Cable's Ohio subsidiary (approximately $210 million of which
would be drawn upon entering into such agreement) and a $260 million two year
revolving credit facility for V Cable's Long Island subsidiary (approximately
$220 million of which would be drawn upon entering into such agreement). The
initial amounts drawn under the respective revolving credit facilities will be
used to repay all remaining VC Holding debt to GECC. Both the Ohio and Long
Island credit facilities would be entered into upon completion of final
documentation and the receipt of any required franchise or regulatory
approvals.
 
  The letter of intent between the Company and GECC is a general, non-binding
letter of intent. There can be no assurance that the Proposed V Cable
Transactions will be consummated or will be consummated in the form described
in the letter of intent. If the Proposed V Cable Transactions, or similar
transactions with respect to V Cable, fail to occur, then V Cable believes
that it is likely that it will be unable to meet certain of its financial
covenants as of December 31, 1995. To remedy the anticipated covenant
defaults, V Cable may request waivers and/or amendments to its credit
agreement and/or seek equity contributions from the Restricted Group. During
1995, the Restricted Group has made equity contributions aggregating $2.3
million to enable V Cable to meet certain of its financial covenants. There
can be no assurance as to V Cable's ability to accomplish either of these
alternatives in the future or the terms or timing of such alternatives.
Assuming any covenant defaults are waived or cured, V Cable anticipates that
its cash flow from operations and amounts available under the VC Holding
revolving credit line will be sufficient to service its debt, to fund its
capital expenditures and to meet its working capital requirements through
1996.
 
NBC OPTION
 
  On July 12, 1995, Rainbow Programming consummated the purchase of NBC's
interest in SportsChannel (New York) Associates and Rainbow News 12 Company
pursuant to the NBC Option, which Rainbow Programming entered into with NBC in
connection with the MSG Acquisition, for an aggregate purchase price of
approximately $95.5 million, and, effective as of such date, consolidated the
results of operations of SportsChannel (New York) Associates and Rainbow News
12 Company with those of the Company. The purchase was financed principally by
a drawdown of approximately $94.0 million under Rainbow Programming's $202
million amended and restated credit facility and an equity contribution by the
Company of the balance of the purchase price.
 
ISSUANCE OF SERIES G PREFERRED STOCK
 
  On September 26, 1995, the Company issued 2.5 million shares of its 11 3/4%
Series G Redeemable Exchangeable Preferred Stock (the "Series G Preferred
Stock") with an aggregate liquidation preference of
 
                                     S-15
<PAGE>
 
$250 million. The Company is required to redeem the Series G Preferred Stock
on October 1, 2007 at a redemption price per share equal to the liquidation
preference of $100, plus accrued and unpaid dividends thereon. Before October
1, 2000, dividends may, at the option of the Company, be paid in cash or by
issuing fully paid and nonassessable shares of the Series G Preferred Stock
with an aggregate liquidation preference equal to the amount of such
dividends. On and after October 1, 2000, dividends must be paid in cash. The
terms of the Series G Preferred Stock permit the Company, at its option, after
January 1, 1996 to exchange the Series G Preferred Stock for the Company's 
11 3/4% Senior Subordinated Debentures due 2007 (the "11 3/4% Debentures") in an
aggregate principal amount equal to the aggregate liquidation preference of
the shares of Series G Preferred Stock.
 
  Of the net proceeds of approximately $239.3 million received by the Company
from the issuance and sale of the Series G Preferred Stock, $136.2 million has
been applied to repay borrowings under the Company's Credit Agreement and
$103.1 million will be used to redeem the Company's outstanding Series E
Redeemable Exchangeable Convertible Preferred Stock (the "Series E Preferred
Stock") on November 2, 1995 at a redemption price equal to the aggregate
liquidation preference plus accrued and unpaid dividends thereon.
 
CABLEVISION OF BOSTON ACQUISITION
 
  In June 1994, the Company and Cablevision of Boston entered into an
agreement which is designed to give the Company full ownership of Cablevision
of Boston. The agreement provides for the acquisition by the Company of the
interests of Cablevision of Boston which it does not already own in a series
of transactions. See "Condensed Pro Forma Consolidated Financial Information".
Consummation of the transactions would result in the limited partners in
Cablevision of Boston receiving Class A Common Stock of the Company with an
expected aggregate market value of approximately $40 million. Upon
consummation of the acquisition of Cablevision of Boston, the Company expects
Cablevision of Boston to become a member of the Restricted Group. All
outstanding subordinated advances made by the Company to Cablevision of Boston
will become intercompany indebtedness if the acquisition of Cablevision of
Boston is consummated. In addition, the Company, along with certain of its
affiliates, are parties to a lawsuit filed with respect to the Company's
acquisition of Cablevision of Boston. The action is brought on behalf of a
purported class consisting of limited partners in Cablevision of Boston and
seeks, among other matters, to enjoin the proposed acquisition of Cablevision
of Boston and damages. The Company, along with the other defendants, is
defending the action.
 
IMPACT OF PENDING TELECOMMUNICATIONS LEGISLATION ON FCC CABLE RATE REGULATION
 
  Both the U.S. Senate and the House of Representatives have passed
legislation that would significantly relax cable rate regulation. The Senate
bill would modify the 1992 Cable Act's definition of "effective competition"
to deregulate all cable rates, including basic service rates, whenever a
telephone company begins to offer comparable video programming services to
subscribers in a cable operator's franchise area. The Senate bill also limits
the FCC's ability to regulate rates for non-basic services offered by an
operator not subject to "effective competition" only to instances in which an
operator's rates for such services substantially exceed the national average.
 
  The House bill would deregulate non-basic rates charged by a cable operator,
on a franchise area by franchise area basis, as soon as a telephone company
has been authorized to construct video dialtone facilities or has been
authorized by the FCC or local franchising authorities to provide video
programming to subscribers in the operator's franchise area by any means. Non-
basic rates in all franchise areas would be deregulated 15 months after the
date of enactment, whether or not a telephone company has been so authorized
in a particular franchise area. The regulation of rates for basic service
offered by an operator not subject to "effective competition" would remain
unchanged.
 
  The differences between the Senate and House passed bills would need to be
reconciled before the legislation could become law. The Company cannot at this
point predict whether any legislation ultimately will be enacted into law or
the final form any such legislation would take.

COMPANY'S THIRD QUARTER RESULTS
 
  The Company's net revenues for the three and nine months ended September 30,
1995 increased 24% and 33%, respectively, over the corresponding 1994 periods.
Increases of 12% and 21%, respectively, for the three and nine month periods
were attributable to acquisitions made during 1994 and 1995. The remaining
increases of 12% in each period came primarily from internal growth in the
average number of subscribers (approximately 147,500 (10%) for the nine month
1995 period over the same 1994 period).
 
  Net losses for the three and nine months ended September 30, 1995 amounted
to $41.7 million and $237.1 million, or $1.85 and $10.29 per common share
(after preferred dividend requirements), as compared to net losses of $66.9
million and $178.7 million, or $2.93 and $7.82 per common share (after
preferred dividend requirements), for the same periods in 1994. The increase
in net loss for the nine month 1995 period was primarily due to the net losses
of companies acquired during 1994. The decrease in net loss for the three
month 1995 period reflects gains related to the sale of one cable affiliate
and interests in one programming partnership aggregating approximately $36.2
million.
 
  At September 30, 1995, the Company's cable television systems served
approximately 1,887,000 subscribers, representing 62% penetration of homes
passed and an increase of 119,000 subscribers in the first nine months of
1995. Recurring average monthly revenue per subscriber was $36.69 in September
1995.

                                USE OF PROCEEDS
 
  The net proceeds to be received by the Company from the Offering are
estimated to be $243.5 million. The Company will initially apply the net
proceeds from the Offering to the repayment of borrowings under the Company's
Credit Agreement. The Company expects to raise additional amounts under the
Credit Agreement in the future for general corporate purposes. 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 8.4%, and mature in installments over the 1997-2003
time period. See "Management's Discussion and Analysis--Liquidity and Capital
Resources".
 
  The Company is concurrently with the offering of the Notes offering its
Series I Preferred Stock represented by Depositary Shares with an aggregate
liquidation preference of $300 million. The Company expects to use the net
proceeds from that offering (estimated to be $289.3 million) to repay
borrowings under the Credit Agreement.
 
  The consummation of the offering of the Depositary Shares is not a condition
to the consummation of the offering of the Notes offered hereby, nor is the
consummation of the offering of the Notes a condition to the offering of the
Depositary Shares.

FOOTNOTES
 
(1) See "Management's Discussion and Analysis--Liquidity and Capital
    Resources" and the Consolidated Financial Statements for a description of
    the bank indebtedness. This indebtedness consists of the Company's
    indebtedness under its principal bank credit agreement, the New Jersey
    subsidiary credit agreement and the Cablevision of NYC credit agreement.
    These amounts do not include approximately $22.7 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 credit
    agreement.
(2) On July 12, 1995, Rainbow Programming incurred an additional approximately
    $94.0 million of indebtedness in connection with the exercise of the NBC
    Option.
(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. NYC LP Corp.'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) Issuable in connection with the Proposed V Cable Transactions. See "Recent
    Developments--Proposed V Cable Transactions" for a discussion of such
    transactions.

     Transactions.

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 Notes 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 Notes will mature on November  , 2005.
 
  The Notes will bear interest from November  , 1995 at a rate of   % per
annum, payable semi-annually on May    and November    of each year,
commencing May  , 1996. Interest on the Notes 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 Note was registered at the close of business on the preceding
and    , respectively, subject to certain exceptions. The Notes will be
unsecured obligations of the Company. The Notes will be subordinated to all
existing and future Senior Indebtedness of the Company.
 
  Principal of and premium, if any, and interest on the Notes will be payable,
and the Notes 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 Notes.
No service charge will be made for any registration of transfer or exchange of
Notes, except for any tax or other governmental charge that may be imposed in
connection therewith.
 
  The Indenture will not contain any provisions that limit the ability of the
Company to incur indebtedness or that afford Holders of the Notes 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 Notes will not be entitled to the benefits of a sinking fund.
 
OPTIONAL REDEMPTION
 
  The Notes will be subject to redemption at any time on or after November  ,
2000, 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 November    of the years indicated:

and thereafter at 100% of the 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 Notes are to be redeemed, the Trustee shall
select the Notes 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 Notes other than through the issuance of subordinated
indebtedness, preferred stock or common stock.
 
SUBORDINATION
 
  The indebtedness represented by the Notes 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 Notes or before any
acquisition of Notes 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 Notes (other than payments made in
Junior Securities) or to acquire any of the Notes or on account of the
redemption provisions of the Notes (except mandatory redemption payments made,
in accordance with the terms of the Notes, in Notes 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 will provide 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 Notes.
 
  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 Notes (or the
Company's 10 3/4% Debentures due 2004, the 9 7/8% Debentures due 2013 and the
9 7/8% Debentures due 2023 (collectively, the "Existing Debentures")) may
recover more, ratably, than the Holders of the Notes.
 
                                     S-29
<PAGE>
 
  A Holder of Notes by his acceptance of Notes 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 June 30, 1995, adjusted to
give pro forma effect to the transactions described under "Capitalization" and
the application of the net proceeds to the Company from the Offerings, would
have been approximately $563.6 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
June 30, 1995, such Cash Flow Ratio was approximately 7.7 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 Notes 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
Notes if it is not subordinate in right of payment to Senior Indebtedness at
least to the same extent as the Notes are subordinate to Senior Indebtedness.
 
  Limitation on Restricted Payments. The Indenture provides that, so long as
any of the Notes 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%
 
                                     S-30
<PAGE>
 
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
the 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 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 June 30, 1995, the Company would have been permitted to make
Restricted Payments of $332.0 million, and after giving effect to the offering
of the Depositary Shares and the redemption of the Series E Preferred Stock,
approximately $519 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 9:1.
 
  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") will be the Trustee under the Indenture 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 Notes 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  % of the principal amount of
the Notes. The Underwriters may allow, and such dealers may reallow, a
discount not in excess of  % of the principal amount of the Notes 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 Notes. The Company does not intend to list
the Notes 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 Notes 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 Notes or that an
active public market for the Notes will develop. If an active public market
does not develop, the market prices and liquidity of the Notes may be
adversely affected.
 
  Each of Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch")
and Bear, Stearns & Co. Inc. ("Bear Stearns") 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, Merrill Lynch, Bear Stearns and Morgan Stanley &
Co. Incorporated were the initial purchasers in the offering of the Company's
Series G Preferred Stock in September 1995 and are prospective underwriters of
the Company's Series I Preferred Stock represented by depositary shares. An
affiliate of Toronto Dominion Securities (USA) Inc. is an agent and lender
under the Company's Credit Agreement and is a lender to certain affiliates of
the Company. In addition, such affiliate is the holder of the Company's Series
E Preferred Stock which will be redeemed on November 2, 1995 by the Company
out of the proceeds of the Company's issuance and sale of the Series G
Preferred Stock.
 
  In connection with the Offering, the Company has agreed to indemnify the
Underwriters against certain liabilities, including liabilities under the
Securities Act of 1933, as amended.
 
                               VALIDITY OF NOTES
 
  The validity of the Notes 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.
