First Super Bowl trivia - the power of TV.
Network crew fights
Erased tape
2 second half kickoffs.
This game is the only Super Bowl to have been broadcast in the United States by two television networks simultaneously (no other NFL game was subsequently carried nationally on more than one network until December 29, 2007, when the New England Patriots faced the New York Giants on NBC, CBS, and the NFL Network). At the time, NBC held the rights to nationally televise AFL games while CBS had the rights to broadcast NFL games. Both networks were allowed to cover the game. During the week, tensions flared between the staff of the two networks (longtime arch-rivals in American broadcasting), who each wanted to win the rating war, to the point where a fence was built between the CBS and NBC trucks.[29]
All known broadcast tapes of the game in its entirety were subsequently wiped by both NBC and CBS to save costs, a common practice in the TV industry at the time as videotapes were very expensive (one half-hour tape cost around $300 at the time, equivalent to $2260 in 2019 dollars), plus it was not foreseen how big the game was going to become.[33] This has prevented studies comparing each network's respective telecast.
In January 2011, a partial recording of the CBS telecast was reported to have been found in a Pennsylvania attic and restored by the Paley Center for Media in New York.[33] The two-inch color videotape is the most complete version of the broadcast yet discovered, missing only the halftime show and most of the third quarter.

Nothing was odder, though, than what happened when the third quarter began – something that really showed you JUST how awkward the whole affair was. You see, when the Green Bay Packers kicked off to the Kansas City Chiefs to start the second half, NBC was still in a commercial!
Not a big deal, though, right? So NBC was a little late – they’ll catch up, no?
No.
The on-field officials were notified of the “problem” and actually called the play dead and had them RE-KICK the kick-off!!!
