Coca-Cola recently introduced its new low-carb C2 cola in the company's most aggressive media blitz since Diet Coke was released in the early 1980s. The cola giant supported C2's rollout with a marketing campaign that included television, radio, outdoor, cinema and Internet advertising. The campaign carried the tagline "Half the carbs. Half the cals. All the great taste."

The new Coca-Cola product arrives at a time when low-carb diet crazes are sweeping the nation and producing unlikely products in spades, from low-carb beer to low-carb doughnuts. Executives at the company claim that C2 is a response to customers that seek choices that fit their lifestyles. Weight-conscious consumers want to keep enjoying the cola taste that Coca-Cola delivers, but with the option of a lower-carb, lower-cal soft drink. Coca-Cola C2 gives that freedom of choice.

In the past two years, Coke has introduced four new products in the cola category -- Vanilla Coke, Diet Vanilla Coke, Diet Coke with Lemon, and, most recently, Diet Coke with Lime. The company's newest product features the familiar Coca-Cola trademark in black on a "Coca-Cola red" background, to provide a distinctive visual difference between Coca-Cola C2 and the flagship brand, Coca-Cola classic.
