New Coke was the reformulation of Coca-Cola introduced in 1985 by The Coca-Cola Company to replace the original formula of its flagship soft drink, Coca-Cola (also called Coke). New Coke originally had no separate name of its own, but was simply known as "the new taste of Coca-Cola" until 1992 when it was renamed Coca-Cola II.
The American public's reaction to the change was negative and the new cola was a major marketing failure. The subsequent reintroduction of Coke's original formula, re-branded as "Coca-Cola Classic", resulted in a significant gain in sales, leading to speculation that the introduction of the New Coke formula was just a marketing ploy.
New Coke is still available in Yap and American Samoa.
