Even New Coke was a flop.
I think the Jury's still out on this one. Theory has it, that you "forget" the taste of Coke after 6 months of not having it. In order to change your formula (Coke), you have to somehow get your customer base to forget the "old" taste before changing it. But how? Release something that, in the public eye attempts to thwart that Pepsi Challenge. When the New Coke flops, Coke will release 'Classic', returning their customers to what they
perceive as the real thing, taking those Pepsi Challenges by storm. THAT, at least worked like a charm. Pepsi has never posed that challenge again. 'Ray, when someone asks you which drink is your favorite, you say,..."COKE!" '
Ahh, who knows. Fun stuff....
