Diet Coke was Coca-Cola’s 1982 cola brand created as a lower-calorie alternative.
It was the first Coca-Cola product to use the “Coke” name rather than simply extending the original Coca-Cola name. The launch responded to growing consumer interest in reduced-calorie soft drinks and built on the company’s earlier experience with Tab.
Diet Coke used a different formula from the original Coca-Cola and was marketed as a separate branded product. Its silver packaging and strong visual identity helped distinguish it on shelves and in advertising.
Diet Coke is often confused with Coca-Cola Light, which is the name used in many international markets for a closely related diet cola. Coke Zero, introduced later, was positioned around Coca-Cola taste with zero sugar rather than Diet Coke’s original brand identity.
