Chocolate, as a flavor, is immensely popular for ice cream and candy and cake. Why not for soft drinks?

I recently returned from a fantastic Caribbean cruise and I noticed that all of the major soft drink labels (Pepsi, Coke, etc) all tasted different in the different islands that I visited. Interestingly, my best friend (who came from Europe) told me the same thing from the countries over there.

So, why do the soft drinks taste differently even though they are from the same company? Anyone know?
