which nfl team is named after a credit card company

The NFL team named after a credit card company is the Los Angeles Chargers. The team's original owner, Barron Hilton, had a credit card company called Carte Blanche. He chose the name "Chargers" as a promotional idea related to his credit card business, meaning people who would "charge" purchases on the card. Although Hilton later denied that the team name was directly inspired by the credit card, the connection is well documented and part of the team's history.
