Well here's one from the memory vault.
Do you like Golden Grahams cereal by General Mills? It's one of my favorites because it tastes so good. But I'm guessing that Golden Grahams arose from the failure of an earlier attempt at a cereal that tried to taste like graham crackers.
It was 1967 and General Mills released, "Clackers - the Graham Cereal".
General Mills was so sure they had a hit on their hands that they gave the green light to a very funny television ad campaign. On second thought, me and my school friends found the ads funny, my mom hated the TV commercials!
There was a problem, the ads were a hit with kids but the cereal tasted like "graham cracker flavored" sawdust. Had the cereal tasted good there would not have been a problem.
My parents didn't mind the ads at first, but over time the commercials became so annoying that they would use the remote to change the channel, something they might not have done if the cereal tasted good.
I believe the failure of Clackers was the push that created Golden Grahams.
