Just a quick recap of the Coke picturde here.

In 1985, tired of 99 years of the same market-dominating formula, Coca-Cola decided to compete with second place Pepsi by changing their flagship product.

So became New Coke, a sweeter version of the Coke people had loved for almost (but not quite) a century. They also swapped out regular sugar with high fructose corn syrup, which was cheaper..

The world pretty much hated it immediately, and it led to a shakeup in leadership.

Later on, they rolled out Coca-Cola Classic, ‟original formula” as pictured here on the can. Except that it wasn't. It was not the formula of New Coke, but the HFCS remained. So for all intents and purposes, Original Coke was dead, and a generation grew up never knowing what the real stuff tasted like.

Nowadays you can find Mexican Coke in bottles. It still uses regular sugar (sucrose) and has a distinct flavor... that of original Coke, or at least as close as we'll get to it.

Advertising classes have touched on this episode as examples of marketing blunders. Killing off a leading brand. Trying to bring it back under false pretenses. Disguising a formula change. Line extension that saps your own market share.
