7-Up is a lemonade brand of DrPepper/SevenUp Company, which started to produce bottled products in 1987. Outside the United States, 7-up is a registered trademark of PepsiCo. Qixi was originally named Bib-labellithiatedlermon-limesoda, and started production in St. Louis, Missouri in 1929. It originally contained lithium citrate, which is a sedative. Many drinks in the early days contained pharmaceutical ingredients. This ingredient was removed from the formula in 1950.

7 Up was created by Charles Gligo, the founder of HowdyCorporation. Its previous product was called Howdy orange soda. After more than two years of trying different formulas. Charles hopes that this new formula can bring different feelings to consumers. He started producing its products two weeks before the financial crisis of 1929. Charles never explained why the product was called 7up. The most common saying is that 7 and U indicate that 7-up contains 7 kinds of spices and has been carbonated.
