The Los Angeles Chargers were one of the founding members of the American Football League which was formed to rival the NFL in 1960 by owners that had to be loaded to fund their franchises.
The Chargers’ franchise was owned by hotel heir Barron Hilton and after originally putting the team in Los Angeles, he decided to move it to San Diego after one season. Hilton reasoned the team couldn’t compete financially in the same market with the LA Rams.
After the AFL merged with the NFL in 1970 when the Steelers began playing the Chargers, Pittsburgh won the first six contests.
