It was my understanding Hilton named the team the Chargers because he was coming out with a new credit card called “Carte Blanche”. He thought the name chargers would help promote the use of his new card. In fact I had the card for a while in the early 60’s.
Maybe for promotion, but carte Blanche already started.
Are Carte Blanche and Diners Club cards still in existence??
I had a Diners Club many years ago, but gave it up since so many places also accept Visa and MasterCard. I didn’t want to have too many credit cards.
