Diet Rite is an American brand of no-calorie soft drinks that was originally distributed by the RC Cola company.
NutraSweet brand aspartame was added upon its introduction to the market, and in 1987 the saccharin was replaced entirely with the complete elimination of caffeine.
It became the first major diet soda in the United States to use neither aspartame nor saccharin as a sweetener.
In 2005, "Pure Zero" was added to the name, and a cherry cola flavor was introduced in 2006.
[2] In the early 1960s The Paris Sisters sang a jingle for a Diet Rite television commercial, with the line "Stay thin with the best-tasting cola of all!".
