                                EXPLANATORY NOTE

     CBS Corporation, a Delaware corporation (the "Registrant"), is filing with
the Securities and Exchange Commission this Post-Effective Amendment No. 1 to
its Registration Statement on Form S-8 (File No. 333-36440) (the "Registration
Statement") as a result of the merger (the "Merger") of Viacom Merger Sub Inc.,
a Delaware corporation, with and into the Registrant on December 31, 2005, with
the Registrant as the surviving corporation of the Merger. Upon completion of
the Merger, the name of the Registrant was changed from "Viacom Inc." to "CBS
Corporation." This Post-Effective Amendment No. 1 is filed to reflect (i) the
change in the name of the Registrant, (ii) a reduction in the par value of the
Registrant's Class B Common Stock registered under the Registration Statement
from $0.01 to $0.001 per share, (iii) the removal of the Westinghouse Savings
Program because no shares are currently being offered under this Registration
Statement pursuant to such plan and (iv) the removal of the CBS Employee
Investment Fund, the Infinity Broadcasting Corporation Employees' 401(k) Plan
and the Infinity Broadcasting Corporation Employees' 401(k) Union Plan, which
subsequent to the original filing of this Registration Statement were merged
into the CBS Corporation 401(k) Plan (formerly known as the Viacom Inc. 401(k)
Plan), pursuant to which shares of the Registrant are being offered under the
Registrant's Registration Statement filed on February 8, 2002 (File No.
333-82422).






                                   SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, the Registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-8 and has duly caused this Post-Effective
Amendment No. 1 to Registration Statement No. 333-36440 on Form S-8 to be signed
on its behalf by the undersigned, thereunto duly authorized, in the City of New
York, State of New York, on the 13th day of January, 2006.
