Diet Coke (also known as Diet Coca-Cola, Coca-Cola light or Coke Light) is a sugar-free soft drink produced and distributed by The Coca-Cola Company. It was first introduced in the United States on August 9, 1982, as the first new brand since 1886 to use the Coca-Cola trademark. The product quickly overtook the soft drink Tab in sales.
