Via the WSJ:
Football fans know what happened in Super Bowl I. The game, which was played on January 15, 1967, was the first showdown between the NFL and AFL champions. It ended with the Green Bay Packers stomping the Kansas City Chiefs, 35-10.
Unless they were one of the 61,946 people at the Los Angeles Memorial Coliseum that day, or one of the fans who watched it live on NBC or CBS, there's one thing that all football fans have in common: They've never actually seen the game.
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.
WSJ's J.R. Whalen reveals some little-known facts about Super Bowl I, played in 1967. Like, for instance, it wasn't even called the Super Bowl.
