Diet Pepsi hasn't changed much throughout the years. It's the same Diet Pepsi that was right for Ray Charles, your Uncle Ray and, yes, even that Ray from the diner. It's said to look good pretty much anywhere whether it's in a can, bottle or an extreme close-up. It's the same beverage your flower-crown-wearing hippie mom drank when she was young, and here she is still enjoying it many years later. Diet Pepsi thinks its light, crisp and refreshing taste is always the right one.
