The reformulated version of Coca-Cola Classic launched in 1985 to help fight off the hard-charging Pepsi. It prompted outrage among hardcore Coca-Cola Classic fans, and less than three months later, Coca-Cola went back on its decision.

Coca-Cola's Sprite Remix popped up in 2003, and it quickly developed a rabid fan base. Coke would expand its Sprite Remix flavors twice in the next two years, adding Berryclear and Aruba Jam to its portfolio following the original Tropical.
