The time is right! For Pepsi Light!
Pepsi Light was a saccharin-sweetened diet soda introduced in 1975.
Aimed straight at the US youth market. It had a lemon-twist, was calorie-free and came in pretty blue packaging. The kids had no defence.
The saccharin aftertaste was not pleasant, though, and when the lemon flavouring was removed in the 1980s, the product tanked.
