It's not every day that the Coca-Cola Company has to reverse a formula change, but when it does, you can bet we'll be hearing it about if for many years. Indeed, 29 years after a consumer revolt made the company abandon its infamous "New Coke" reformulation within a mere 79 days and return to the "classic" formula, comparisons to the current brouhaha over its flip-flop on changing Vitaminwater's formula are inevitable. This time, thanks to social media,, it took Coca-Cola only two months to reverse course.
