What was Coca-Cola’s first brand to use the name “Diet Coke”?

Diet Coke was Coca-Cola’s first brand to use the name “Diet Coke.”

Introduced in 1982, Diet Coke became the company’s first cola marketed nationally under a diet-focused Coca-Cola name. It was formulated as a low-calorie alternative for consumers who wanted the Coca-Cola brand without the calories of regular Coca-Cola.

Tab preceded Diet Coke as a Coca-Cola diet soft drink, but it was marketed under its own name rather than as “Diet Coke.” That distinction is why Tab is a common but incorrect answer to this wording.

Coca-Cola later introduced other reduced- or zero-calorie products, including Coca-Cola Zero in 2005. Those products belong to later stages of the company’s diet-cola history.
