Original sentence: However, he is best known for the failed launch of New Coke, widely remembered as one of the greatest marketing blunders of all time (although it had actually succeeded in some regions of the country)
Edited sentence: After 78 days and millions of dollars wasted in what is regarded as the biggest new product failure ever...Coke abruptly admitted its mistake and withdrew the New Coke brand ...much to the embarassment of Coke and glee of Pepsi.Essentially Coke under Zymans leadership as CMO was falling behind Pepsico in the now famous Cola wars of the 80's.He describes it as a failure to understand consumer affinity towards the core essence of the brand which was consistency and all things American...consumers viewed changing that as sacrilege ...even if the new flavor tasted better.However, he is best known for the failed launch of New Coke.This launch is widely regarded as the greatest marketing blunder of all times.This led to a huge consumer back-lash and protest.Zyman came up with the bright idea of coming up with a new flavour for Coke - a brand close to every Americans heart for consistency and American values and re-launching it as New Coke.Zyman details this story in his books the "End of Marketing as we know it" and the "End of Advertising as we know it"
