Sec.  76.95   Exceptions.

   (a) The provisions of  Sec.  Sec. 76.92 through 76.94 shall not apply to a cable
   system serving fewer than 1,000 subscribers. Within 60 days following the
   provision of service to 1,000 subscribers, the operator of each such system

   the broadcast of a live sports event by that station or by a lower priority
   station against which a cable community unit would otherwise be required to
   provide  non-duplication  protection  following  the scheduled time of
   completion.
