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.
Pepsi Zero Sugar
Pepsi Zero Sugar competes in the energy drink market, as is implied by it being marketed as an 'Invigorating Cola.' Compared with other common energy drinks, Pepsi Zero Sugar gives the consumer a relatively low dose of caffeine. Pepsi Zero Sugar provides 5.75 mg caffeine per 30ml, while Red Bull provides 9.64 mg/30ml, AMP Energy provides 8.93 mg/30ml, Monster Energy provides 10 mg/30ml and Cocaine provides 33.14 mg/30ml. Pepsi Zero Sugar commercials present the beverage as an alternative to Diet Pepsi.
