On November 12, 1955, an elderly Biff Tannen traveled from 2015 to give his younger self a sports almanac that would give him the results of sporting events for the next 45 years, allowing himself to bet on the outcomes and get rich. When the teenage Biff didn't believe that the book was real, the elderly Biff turned on the radio and correctly predicted the outcome of the college football match between UCLA and Washington.
On November 13, 1955, Biff drove his grandmother to Las Vegas. He was repeatedly trying to get his grandmother to bet on NFL football matches for him at the Turf Club since the legal age to gamble was 21, and at 18, he was underage. He gave her a twenty dollar bill that he stole from a table to his grandmother to bet on the Chicago Bears. She didn't bet on the Bears, and they lost against the Los Angeles Rams, making Biff twenty dollars poorer. Biff told her to make another bet, on the Washington Redskins. However, when they beat the San Francisco 49ers, she only gave Biff back his twenty dollars, and kept the rest for herself.
In 1993, Doc Brown traveled to Wisconsin on December 31, 1969 to watch the NFL championship game. He stood at the goal line in the final moments of the game and declared a touchdown. Doc hung a black and white photograph of this moment at his chicken restaurant.
