In a bizarre confluence of events, neither network preserved a tape. All that survived of this broadcast is sideline footage shot by NFL Films and roughly 30 seconds of footage CBS included in a pre-game show for Super Bowl XXV. Somehow, an historic football game that was seen by 26.8 million people had, for all intents and purposes, vanished.
The long search may finally be over. The Paley Center for Media in New York, which had searched for the game footage for some time, has restored what it believes to be a genuine copy of the CBS broadcast.
