So I hate summer and I spend most of the hot and humid days of June, July, and August sitting in front of a fan and drinking Diet Coke (and Diet Pepsi - yes, I like both). And that got me thinking about New Coke.

Remember that? It was the disastrous reformulation of the Coke taste that people didn't really like and it came and went rather quickly in the mid-80s (though you could still get it in some areas as recently as 2002!). Wikipedia has the history of New Coke (long, but very much worth the read), and here are the commercials that introduced it to the world.
