Does anyone remember Pet Rocks? They came out in 1975 and the fad really only lasted about 6 months. However, in that short time the creator, Gary Dahl became a millionaire. After listening to his co-workers complain about their animals, Gary decided to make the perfect pet using ordinary rocks. These pets never needed food, water, grooming, exercise, or pet care. He took action and surprisingly enough, he made money.
I never had a Pet Rock. I always wanted one, but my mom wouldn't dish out the $3.95 for a plain rock in a little cardboard box. What a mean mother. The originals aren't available anymore, but every now and then you can find them on eBay.
However, did you know Pet Rocks are still out there? In 2009, Martin Abrams bought the rights to Pet Rocks and began manufacturing them again. You can visit their website here. They're kind of cool looking, but with a little paint, most of us could make our own. I have to admit, the new ones are not as unique as the plain rocks Gary used from a building supply store for pennies each.
