Item 1. Security and Issuer This Amendment No. 4 to Schedule 13D on the Class A Common Stock of Viacom Inc. (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 February 7, 1997. Unless otherwise indicated, all capitalized terms used herein but not defined herein shall have the same meaning as set forth in 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. ("Ento- leter"), Lynch Telecommunications Corporation ("Lynch Telecom"), Lynch Telephone Corporation ("Lynch Telephone") and Inter-Commu- nity Telephone Company ("Inter-Community") (collectively, "Lynch and its affiliates"), engage in various aspects of the securities business, primarily as investment adviser to various institution- al and individual clients, including registered investment companies and pension plans, as broker/dealer and as general partner of various private investment 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.
