Diet Coke (also known as Diet Coca-Cola, Coca-Cola Light or Coke Light; the latter two are usually found in European countries) 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.


Diet Coke was sweetened with aspartame after the sweetener became available in the United States in 1983; to save money, this was originally in a blend with saccharin. In other countries, in which cyclamates are not banned (as they were in the U.S. and the United Kingdom in 1970), Diet Coke or Coca-Cola Light may be sweetened with a blend containing cyclamates, aspartame, and acesulfame potassium.

In 2005, under pressure from retailer Wal-Mart (which was impressed with the popularity of Splenda sweetener), the company released a new formulation called "Diet Coke sweetened with Splenda". Sucralose and acesulfame potassium replace aspartame in this version. Early sales were weaker than anticipated; however, Coca-Cola did little advertising for the brand, investing money and advertising in Coca-Cola Zero instead. By late 2009, some distributors had stopped supplying Diet Coke sweetened with Splenda.

Diet Coke does not use a modified form of the Coca-Cola recipe, but instead an entirely different formula. The controversial New Coke, introduced in 1985, used a version of the Diet Coke recipe that contained high fructose corn syrup and had a slightly different balance of ingredients. In 2004, Coca-Cola introduced Coca-Cola C2, which it claims tastes much closer to Coca-Cola but contains half the carbohydrates. In 2005, the company introduced Coca-Cola Zero, a sugar-free variation of regular Coca-Cola.
