query: Do Diet Coke and regular Coke taste different?
passage: 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[1] and introduced in the United States on August 9,[2] 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.
passage: Double Cola
Double Cola was formerly available in a somewhat wider area of the South. Yet Double Cola is a distinctive part of culture in Southern Indiana, especially around Evansville (for example, Double Cola Fields). It was once marketed as a lower-cost alternative to Coca-Cola and other soft drinks, but Double Cola is now marketed as a premium brand in that area, with the same or higher price than Coca-Cola or Pepsi-Cola. Diet versions of both Double Cola and Ski have been developed in recent years. The "Jumbo" line of fruit-flavored drinks has been expanded to include peach, strawberry, pineapple, fruit punch, root beer, and blue creme soda. Some of these drinks are available only in very limited areas.
Speculation that expansion to Middle Eastern markets was at least in part a chance to exploit the company's low profile and consequent lack of political connotations now inherent in the Coke–Pepsi struggle. Though the Double Cola company's international sales are not as large as Coke or Pepsi, their presence in South Asia, South America and the Middle East comprises their international market. Double-Cola, Oranta and Chaser are the main products sold in their foreign markets.
