The Rams moved to St. Louis in 1995 and renamed the team St. Louis Rams. In January 2016, the Rams and the NFL announced that the team would return to Los Angeles.

The club began play in 1960 as a charter member of the American Football League (AFL), and spent its first season in Los Angeles before moving to San Diego in 1961.

As of 2010, the team's policy was to have the Chargers Hall of Fame committee evaluate candidates for a player's number to retire after the player has retired from the league after five years. The committee consisted of Chargers Executive Vice President A. G. Spanos, Chargers public relations director Bill Johnston, San Diego Hall of Champions founder Bob Breitbard, and the presidents of the San Diego Sports Commission and the Chargers Backers Fan Club. There are few recognized guidelines in sports regarding retiring numbers, and the NFL has no specific league policy. "You have to have enough numbers for players to wear," said NFL spokesman Greg Aiello. The Chargers have rarely retired numbers. The "San Diego Union-Tribune" wrote, "The [Chargers] tend to honor their heritage haphazardly."
