Diet Coke
Diet Coke (called Coca-Cola Light in some countries) is a sugar-free and no-calorie soft drink produced and distributed by The Coca-Cola Company. It contains artificial sweeteners instead of sugar. Unveiled on July 8, 1982 and introduced in the United States on August 9, it was the first new brand since 1886 to use the Coca-Cola trademark. The product quickly overtook the company's existing diet cola, Tab, in sales.
Mexican Coke
However, participants in a different double-blind taste test overwhelmingly preferred American Coca-Cola. Participants in taste tests conducted by Coca-Cola reported no perceptible differences in flavor between American Coke and the Mexican formulation.
