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.
Storm (soft drink)
Storm was a lightly carbonated, caffeinated lemon-lime flavored soft drink. It was test marketed by PepsiCo in some areas of the U.S. in 1998 as part of Pepsi's attempt to become more competitive in the U.S. clear lemon-lime soda market, one which was dominated by Coca-Cola's Sprite. Storm differed from Sprite in that its flavor was uniquely subtle and had a very slight bitterness to it, as well as having caffeine.
