Pet Rock

Owning a dog or cat comes with responsibility, some people may not have the time or the patience for a pet, so in 1975 Gary Dahl created “Pet Rock.” Dahl sold his rocks on a bed of hay for about $4 and packaged it inside of cardboard box that looked like a pet carrier and a training manual. He marketed the rock as a “hassle free” pet and became so popular that his profits exceeded past a million. The fad didn’t last long, but Gary Dahl had already made his fortune.
