[1] Grigg came up with the formula for a lemon-lime soft drink in 1929, and the product was launched two weeks before the Wall Street Crash of 1929.

It is also used as a mixer for highball alcoholic lemon-lime soda cocktails, including the 7 and 7 (Seagram's 7 Crown and 7 Up) and CC and Seven (Canadian Club whisky and 7 Up).

[14] This reformulation contains no fruit juice and, in the U.S., is sweetened with high-fructose corn syrup (HFCS).

The manufacturing process used in the production of HFCS has led some public health and advocacy groups to challenge the ad campaign's "natural" claims.

[15] In 2007, after the Center for Science in the Public Interest threatened to sue 7 Up, it was announced that 7 Up would stop being marketed as "100% natural".

The controversy does not extend to other countries, such as the United Kingdom, where HFCS is not generally used in foods, including 7 Up.

Diet 7 Up was later reformulated and advertised as being sweetened with sucralose and acesulfame potassium replacing aspartame.

[citation needed] In 2007, Cadbury Schweppes entered into a licensing partnership with Vita Food Products to produce a line of barbecue sauces and marinades flavored with Dr Pepper, 7 Up, and A&W Root Beer.

[53] Freddie has been described as a hybrid of the rooster Panchito Pistoles from The Three Caballeros and the zany Aracuan Bird from the same film.

[58] Since PepsiCo did not own the rights to 7 Up in the US, certain ads featuring Fido Dido were instead reworked to advertise the company's Slice brand of lemon-lime soda.

[60] In 1974, 7 Up became The Jerry Lewis MDA Labor Day Telethon's first corporate sponsor; this was at a time when its sponsorship was generally limited to trade unions and civic organizations.
