Gary Ross Dahl, who died earlier this year at age 78, will always be remembered for inventing the ‘Pet Rock’, a 1970s novelty toy craze. The brilliant salesman essentially sold rocks for a living, and managed to make millions through his “ridiculously successful marketing scheme.”
Struck by sudden inspiration, Dahl declared that he had no such
trouble with his own pet. “I have a pet rock,” he told the crowd. And
his response was so well received that he began to toy with the idea,
eventually setting up a business around it.
