Before Their Time
The 1970s and ’80s were filled with innovations such as VCRs, cordless phones, and personal computers that changed the way we live. It was also a time of tech flops and marketing missteps even from companies known for innovation, including Apple, Polaroid, and Sony. The irony is, these so-called failures were also successes, anticipating smartphones and other technologies we now take for granted. Most of the originals have long since been consigned to the trash, but if you can find one in your basement or attic it might be worth big bucks.
