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.

This populist version of the story served Coke's interests, however, as the episode did more to position and define Coca-Cola as a brand embodying values distinct from Pepsi than any deliberate effort to do so probably could have done. Allowing itself to be portrayed as a somewhat clueless large corporation forced to withdraw from a big change by overwhelming public pressure flattered customers, as Keough put it, "We love any retreat which has us rushing toward our best customers with the product they love the most." Bottles and cans continued to bear the "Coca-Cola Classic" title until January 2009, when the company announced it would stop printing the word "Classic" on the labels of bottles sold in parts of the southeastern United States. The change is part of a larger strategy to rejuvenate the product's image.
