Item 1.Security and Issuer
This Amendment No. 13 to Schedule 13D on 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 13D
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.
("GSI"), Gabelli & Company, Inc. ("Gabelli & Company"), Gabelli
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

(d) and (e) - On December 8, 1994, the SEC instituted
and simultaneously accepted offers for the settlement of an
administrative proceeding against Gabelli & Company and GAMCO.
The order instituting the proceeding included a finding, which
Gabelli & Company and GAMCO neither admitted nor denied, that
they failed to implement and maintain policies and procedures
reasonably designed to prevent the misuse of material, nonpublic
information by not sepecifically addressing the special
circumstances that arose from their affiliation with Lynch
Corporation, a public company. To resolve this matter, Gabelli &
Company and GAMCO agreed to cease and desist from violating
Section 15(f) of the 1934 Act and Section 204A of the Advisers
Act, respectively. They further agreed to each pay a civil
penalty in the amount of $50,000, and to retain, and adopt the
recommendations of, an independant consultant regarding their
Section 15(f) and Section 204A policies and procedures.
On December 13, 1991, the Virginia State Corporation
Commission entered an order of settlement in final disposition of
matters arising from an allegation that GAMCO had transacted
business in Virginia as an investment adviser without having been
registered as such under Virginia Code Section 13.1-504A or an
exemption therefrom. GAMCO consented to the entry of the order
without admitting or denying the allegation and without a
hearing. The terms of the order provide that GAMCO would pay a
fine and costs totalling fifty-five thousand dollars and would
not transact business in Virginia as an investment adviser unless
it was registered as such under section 13.1-504A or was exempt
from registration.
(f) - Reference is made to Schedule I hereto.
<PAGE>
Item 3. Source and Amount of Funds or Other Consideration
All Reporting Persons used an aggregate of approximate-
ly $5,338,734 to purchase the additional Securities requiring
this Amendment to Schedule 13D. GAMCO and GFI used approximately
$4,150,334 and $1,188,400, respectively, of funds that were
provided through the accounts of certain of their investment
advisory clients (and, in the case of some of such accounts at
GAMCO, may be through borrowings from client margin accounts) in
order to purchase the Securities for such clients.
Item 5. Interest In Securities Of The Issuer
Item 5 to Schedule 13D is amended, in pertinent part,
as follows:
(a) The aggregate number and percentage of Securities
to which this Schedule 13D relates is 2,742,765 shares,
representing 20.64% of 13,284,728 shares outstanding. This
latter number is arrived at by adding the number of shares
reported as being outstanding in the Issuer's most recently filed
Form 10-Q for the quarter ended June 30, 1996 (13,257,163 shares)
to the number of shares which would be receivable by the
Reporting Persons if they were to convert all of the Issuer's
Covertible Preferred stock held by them (27,565 shares) into the
Common Stock of the Issuer. The Reporting Persons beneficially
own those Securities as follows:
