Diet Coke
Diet Coke (called Coca-Cola Light in some countries) is a sugar-free and no-calorie soft drink produced and distributed by The Coca-Cola Company. It contains artificial sweeteners instead of sugar. Unveiled on July 8, 1982 and introduced in the United States on August 9, it was the first new brand since 1886 to use the Coca-Cola trademark. The product quickly overtook the company's existing diet cola, Tab, in sales.
OK Soda
OK Soda had a more "citric" taste than traditional colas, almost like a fruit punch version of Coke's Fresca. It has been described as "slightly spicy" and likened to a combination of orange soda and flat Coca-Cola. It has also been compared to what is known as "suicide", "swampwater" or "graveyard", the resulting mixture of multiple soft drink flavors available at a particular convenience store or gas station's soft drink dispenser.
