7. Pepsi

Year original logo introduced: 2003

Year logo re-designed: 2008

It was easy for cartoonists to make quick work of Pepsi's new logo when it was unveiled in 2008-it reminded some of a bloated belly extending from a T-Shirt, a perfect message for health food hacktivists to get on board with. Though Pepsi has rebranded often over the years, always trying to stay on target with new generations, this was an attempt to speak to The Kids with a minimal dialogue was a flop.
