TaB is a diet cola. It was the first diet soft drink brand produced by the Coca-Cola Company. It was introduced in 1963 and has been reformulated several times. It was initially sweetened with cyclamate. After the Food and Drug Administration (FDA) issued a ban on cyclamate in 1969, saccharin was used. In 1977, the FDA moved to ban saccharin. The ban proposal was rejected by the U.S. Congress, but it did require that all products containing saccharin carry a warning label that saccharin may cause cancer. In the year 2000, Bill Clinton lifted this requirement. A formula revision in 1984 blended saccharin with a small amount of aspartame; this is the formula that is currently marketed in North America. TaB sales have been dwarfed by those of Diet Coke, though enough people still prefer TaB to keep it in production.
