In an effort to cash in on the surging popularity of low-carbohydrate diets, in 2004 both Coca-Cola and Pepsico released reduced-calorie versions of their flagship sodas that contain approximately half the sugar of the regular version. The Pepsi variant, Pepsi Edge, is sweetened with sucralose and corn syrup. The sweetening of the Coca-Cola variant, Coca-Cola C2, is a combination of corn syrup, aspartame, acesulfame potassium, and sucralose. Pepsi discontinued Edge in 2005, citing lackluster sales. Coca-Cola soon followed suit.
