While it may seem completely foreign to the current 18 to 35 demographic, there was a time when credit cards did not exist at all; and when they did come in to being, they were not treated as casually as they are today. While individual merchants issued credit accounts as early as the 1920s, the first card that could be used to pay multiple merchants in a similar conceptualization to the modern credit card was the Diners Club card, a card designed for the wealthy and members of high society to charge travel, entertainment and dining expenses. Unlike modern credit cards, the statement of a Diners Club card required full payment each month. The company also created a subsidiary known as Carte Blanche. While Diners Club International, the company that originally founded the card, still exists, it is now a subsidiary of Discover Financial, having first been bought by the Citigroup in 1981 and later purchased by Discover in 2008.
