Tab Clear was a variation of Tab. It is Coca-Cola's contribution to the short-lived "clear cola" movement during the early 1990s. It was introduced in the United States on December 14, 1992, in the United Kingdom a month later and in Japan in March 1993 to initially positive results. Tab Clear was, however, discontinued after only a short time of marketing in 1994. Unlike most other "clear" soft drinks, Tab Clear contained caffeine and, according to the company, had the flavor of cola.
