Fifty-five years ago, NFL broadcasts were not nearly as smooth as they are today.
In what would become known as the "Heidi Game," NBC once cut away from a shootout between Joe Namath's New York Jets and the Oakland Raiders to show the television film Heidi.
The gist of the story: the Jets and Raiders game ran long thanks to scoring a ton of points and two rivals producing a good amount of penalties playing against each other, so much so that they ran past the broadcast window of the game.
