ダイナースクラブ
McNamara and his attorney, Ralph Schneider, founded Diners Club International on February 8, 1950, with $1.5 million in initial capital. Alfred Bloomingdale joined briefly, then started a competing venture in California before merging his California-based Dine and Sign with Diners Club. McNamara's original conception was to make a card that could have been used as a means of payment in restaurants around New York City; however, he later expanded its usage to other establishments as well including hotels, car rentals, and flower shops. The company started building its customer base by offering their cards to prominent businessmen. Shortly afterward, Matty Simmons, the company's first press agent, started advertising the card in newspapers, magazines, and by sending personal mail to potential customers. Diners Club International was named for being a "club of diners" that would allow patrons to settle their bill at the end of each month through their credit account. When the card was first introduced, Diners Club listed 27 participating restaurants, and 200 of the founders' friends and acquaintances used it.
