Havent u noticed?

Question

they dont make regular coke or pepsi commercial's just diet why

Answer 1

Because we are living in a society that is SOOOO overweight, that we have to only advertise healthier alternatives to products that made us obese in the first place. But it's not true, I still see Pepsi and Coke commercials, but you're right.  Diet soda commercials are WAAAAAY more common.

Answer 2

Lmfao. That's true. Maybe it's because it's so common. Like, everybody know's about Coke and Pepsi cause it's been around for years.
