itwbennett writes "There are tech fads that flare up quickly and then, pouf, they're gone (Tamagotchi, anyone?). And then there are technologies that industry bigwigs predict will follow that familiar pattern and instead end up withstanding the test of time. The Internet, for example, has famously failed to implode, despite dire predictions by Ethernet inventor Bob Metcalfe. And what about TV, the cornerstone of the American living room? Inventor Lee DeForest, known as one of the 'fathers of the electronic age,' declared TV a commercial and financial impossibility, a sentiment that was shared by 20th Century Fox exec Darryl Zanuck. And FCC engineer T.A.M. Craven was absolutely certain back in 1961 that there was 'no chance communications space satellites will be used to provide better telephone, telegraph, television, or radio service inside the United States.'"
