ELI5: What's the difference between Coke Light, Coke Zero and Diet Coke?
gpt
Coca-Cola Light and Diet Coke are different names for the same product in different countries.

Coke Zero is a different drink. Diet Coke isn't just a sugar free variant of Coca Cola - it has an entirely different recipe, and so it has a different taste. Coke Zero, introduces in 2005, uses the same formula as Coca Cola, but with artificial sweeteners. Also, Coke Zero is marketed towards men, since Diet Coke was seen as a "feminine" beverage.
