Just a few more points, or thoughts.... And I love Dr. Pepper AND Coke...
Dr. Pepper tastes like prune juice..but I will agree Diet Dr. Pepper is probably the best tasting diet drink out there.
In many blind taste tests, Pepsi almost always wins out on Coke...but the Coke brand is so strong, one of the strongest ever measured, that people will choose it over any other cola drink.
My personal opinon, is that when Coke switched to corn syrup sugar over straight sugar, what..some time in the early to mid 70s..it never tasted the same. It used to have a bite, kind of a burn when your drank it. Also, purist swore that the smaller 8 (or was it 10?) oz. bottles tasted better than the 12 oz bottles (king size.)
Love or hate the decision in 85' by the CEO of Coke to introduce New Coke..and replace old Coke..it was based on solid market research and business practice. Even in failure, it gave Coke one of the largest free ad sprees ever given to any commercial product..so prevelant that after 20 years it STILL gets front page press.
Best. Greeter.
