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.
Cyclamate is an artificial sweetener that was discovered in 1937 at the University of Illinois by graduate student Michael Sveda. Like many artificial sweeteners, the sweetness of cyclamate was discovered by accident.
