     This Post-Effective Amendment is being filed by the Registrants pursuant to
the  undertaking  that appears in paragraph  (3) of Item 17 of the  Registration
Statement  on  Form  S-3  (Registration   Nos.   33-59356)  (the   "Registration
Statement").  The  Registration  Statement  related to the offering from time to
time of debt securities (the  "Securities")  of Viacom  International  Inc. (the
"Company"), to be unconditionally  guarantied as to payment of principal and any
