Today is the 50th anniversary of the release of the Edsel. They first went on sale on September 4, 1957 and they were, of course, a huge flop.

The following anecdote seems unreal.

After months of sluggish sales, the crack PR team gathered to brainstorm ideas for selling Edsels. They were battered and weary and devoid of ideas until an adman named Walter “Tommy” Thomas blurted out a suggestion.

“Let’s give away a [bleeping] pony,” he said.

Much to Thomas’s amazement, his idea was not only accepted, it was expanded. The geniuses at Edsel decided to advertise a promotion in which every Edsel dealer would give away a pony. It worked like this: If you agreed to test-drive an Edsel, your name would be entered into a lottery at the dealership, with the winner getting a pony.

Ford bought 1,000 ponies and shipped them to Edsel dealers, who displayed them outside their showrooms. Many parents, egged on by their pony-loving children, traipsed in to take a test drive. Unfortunately, many of the lucky winners declined the ponies, opting instead for the alternative — $200 in cash — and soon dealers were shipping the beasts back to Detroit.

Now the Edsel folks were not only stuck with a lot of cars they couldn’t sell, they were also stuck with a lot of ponies they couldn’t give away. The cars were easy enough to store, but the ponies required food. And after they ate the food, they digested the food. And then . . . another fine mess for Edsel.
