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.
Doritos
In 2007, Doritos ran a campaign called "Doritos X-13D Flavor Experiment" where black, unidentified bags of Doritos were on the market for consumers to identify and name the flavor. The only flavor identification on these chips was "All American Classic".
Reincarnations and relaunches of taco-flavored Doritos, including the 2008 "Back By Popular Demand" campaign, were different from the original taco flavor (A sour cream flavor had been added to the recipe around 1985). The taco chips included in the Zesty Taco and Chipotle Ranch "Collisions" bags were thought by customers to be closer to the original, but were later discontinued in most of the United States. In late 2010, the taco flavor recipe that was used in the 1980s returned in a limited edition "retro" styled bag incorporating the original Doritos logo, and in early 2011 the company announced that this incarnation would remain in the permanent product line-up.
