Sprite, a lemon- and lime-flavored drink produced by the Coca-Cola company, does not contain caffeine. Sprite was the company's response to the popularity of the drink 7-Up.
The drink originated in Germany but wasn't introduced to the United States until 1961. The two drinks, Sprite and 7-Up, were competitive until 1989 when Sprite finally took control of the market lead on lemon-lime drinks. There are many variations of Sprite, some specific to certain countries. Sprite on Fire, which contains ginger, for example, was released in Hong Kong in 2003 and China in 2004. These were the only places that it was released. The drinks branding varies from country to country as well, catering to what works for a specific market.
