Business 2.0 (a business magazine) has released their yearly 101 Dumbest Moments in Business 2003.

My favorite is number 53:

The gangbusters success of Frozen Coke—a Slurpee-like concoction sold by Coca-Cola at Burger King restaurants—proves to be a sham in March, when it's revealed that the successful tests were the result of Coke paying $10,000 to buy up Frozen Coke combo meals.

I wonder how oftern this happens since many new products get short term "test runs" in large stores before being made a permanant product offering, quite damaging to the company if that trial run proves unsuccessful...
