About

Diet Coke was released in 1982, which was well after the release of Diet Pepsi in 1964. Prior to the existence of Diet Coke, The Coca-Cola Company marketed Tab as their signature diet cola. Tab was introduced in May 1963. Once Diet Coke was released, it quickly overtook Tab in sales. By the beginning of 1984, Diet Coke only trailed Coke, Pepsi, and 7 Up in popularity.
