Item 1.Security and Issuer
This Amendment No. 23 to Schedule 13D on the Class A
Common Stock of Cablevision Systems Corporation (the "Issuer") is
being filed on behalf of the undersigned to amend the Schedule
13D, as amended (the "Schedule 13D") which was originally filed
on December 11, 1995. Unless otherwise indicated, all
capitalized terms used herein but not defined herein shall have
the same meaning as set forth the Schedule 13D.
Item 2. Identity and Background
This statement is being filed by Mario J. Gabelli ("Mr.
Gabelli") and various entities which he directly or indirectly
controls or for which he acts as chief investment officer. These
entities, except for Lynch Corporation ("Lynch"), Spinnaker
Industries, Incorporated ("Spinnaker"), Western New Mexico
Telephone Company ("Western New Mexico"), Entoleter, Inc.
("Entoleter"), Lynch Telecommunications Corporation ("Lynch
Telecom"), Lynch Telephone Corporation ("Lynch Telephone") and
Inter-Community Telephone Company ("Inter-Community")
(collectively, "Lynch and its affiliates"), engage in various
aspects of the securities business, primarily as investment
adviser to various institutional and individual clients, includ-
ing registered investment companies and pension plans, as
broker/dealer and as general partner of various private invest-
ment partnerships. Certain of these entities may also make
investments for their own accounts.
The foregoing persons in the aggregate often own
beneficially more than 5% of a class of equity securities of a
particular issuer. Although several of the foregoing persons are
treated as institutional investors for purposes of reporting
their beneficial ownership on the short-form Schedule 13G, the
holdings of those who do not qualify as institutional investors
may exceed the 1% threshold presented for filing on Schedule 13G
or implementation of their investment philosophy may from time to
time require action which could be viewed as not completely
passive. In order to avoid any question as to whether their
beneficial ownership is being reported on the proper form and in
order to provide greater investment flexibility and administra-
tive uniformity, these persons have decided to file their benefi-
cial ownership reports on the more detailed Schedule 13D form
rather than on the short-form Schedule 13G and thereby to provide
more expansive disclosure than may be necessary.
(a), (b) and (c) - This statement is being filed by one
or more of the following persons: Gabelli Funds, Inc. ("GFI"),
GAMCO Investors, Inc. ("GAMCO"), Gabelli Securities, Inc.

Performance Partnership L.P. ("GPP"), GLI, Inc. ("GLI"), Gabelli
Associates Fund ("Gabelli Associates"), Gabelli Associates
Limited ("GAL"), Gabelli & Company, Inc. Profit Sharing Plan (the
"Plan"), Gabelli International Limited ("GIL"), Gabelli Interna-
tional II Limited ("GIL II"), Gabelli International Gold Fund
Limited ("GIGFL"), ALCE Partners, L.P. ("ALCE"), Gabelli
Multimedia Partners, L.P. ("Multimedia Partners"), Gemini Capital
Management Ltd. ("Gemini"), Gabelli Foundation, Inc.

penalty in the amount of $50,000, and to retain, and adopt the

filers does not exceed 25% of their total voting interest in the
Issuer and in that event, the Proxy Voting Committee of each of the
Funds shall respectively vote that Fund's shares, and except that,
at any time, the Proxy Voting Committee of each such Fund may take
and exercise in its sole discretion the entire voting power with
respect to the shares held by such Fund under special circumstances
such as regulatory considerations, and except that the power of Mr.
Gabelli and GFI is indirect with respect to Securities beneficially
