Diet soft drink
Tab, Diet Rite, and Fresca (a grapefruit-flavored soda introduced by Coca-Cola) were the only brand-name diet refreshments on the market until Pepsi released Diet Pepsi in the 1960s (initially as  Patio Diet Cola).  Diet 7 Up was also released in 1963 under the name Like.  It was discontinued in 1969 due to the US 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.  Coca-Cola countered by releasing Diet Coke in 1982. After the release of Diet Coke, Tab took a backseat on the Coca-Cola production lines; Diet Coke could be more easily identified by consumers as associated with Coca-Cola than Tab. Additionally, a study was released claiming that saccharin was a possible carcinogen, leading to Coca-Cola's decision to decrease production of Tab. Prompted by the rising popularity of soft drinks, in the mid-1980s some of those in the alcohol industry began to follow their lead with some beer companies putting sugar-free beer on the market.
