When: 1976

In the wake of the '76 U.S. Olympic team winning five gold medals, Don King pitched ABC on the idea of a televised national boxing tournament. In order to bolster the prestige of his event, King allegedly paid The Ring Magazine (an authority on boxing at the time) to falsify the track records and rankings of tournament participants.

The controversial tournament became toxic when one of the tournament fighters informed the media that the tournament was rigged for those who had contractual ties to King. He'd go on to explain that he was told he'd lost his next fight before arriving to the venue. More boxers would come forward with allegations of payoffs, leading ABC to cancel the tournament.
