 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.When diet colas first entered the market beginning with Diet Rite, the Coca-Cola Company had a long-standing policy to not use the Coca-Cola name on any product other than the flagship cola, and so its diet cola was named Tab when it was released in 1963.
