This diet soda was originally introduced in 1963 as Like (not to be confused with 7 Up’s Like Cola from the 1980s). However, it was discontinued in 1969 due to the U.S. government ban of cyclamate sweetener. After reformulation, it was reintroduced as Diet 7 Up in 1970. It was renamed Sugar Free 7 Up in 1973 then back to Diet 7 Up in 1979. Diet 7 Up was reformulated and advertised as being sweetened with Splenda (sucralose); the formula has been retooled and listed these ingredients: filtered carbonated water, natural flavors, citric acid, potassium citrate, potassium benzoate, aspartame, acesulfame potassium, calcium disodium EDTA.
