10 Why is he missing from our history books? He was a naïve young man and was so excited about his invention that he shared his ideas with executives from RCA,(already a corporate giant in the radio world). Unfortunately, Philo T. Farnsworth did not patent his original idea for his television.RCA actually stole his ideas for this technology and passed it off as their own invention. In some history books, RCA is credited with inventing television.Eventually, after years of litigation in the courts, Philo T. Farnsworth won the lawsuit and received credit for the patent but by then most people had already bought their television from RCA and Philo had very little money to produce his own brand of television.

Ladies and gentlemen, this is the most terrifying thing I have ever witnessed... Wait a minute! Someone's crawling out of the hollow top. Someone or... something. I can see peering out of that black hole two luminous disks.. are they eyes? It might be a face. It might be... (SHOUT OF AWE FROM THE CROWD)

The concept of cellular technology had already been created by Motorola's rival, AT&T, whose Bell Labs introduced a system allowing calls to be moved from one cell to another while remaining on the same channel. But AT&T was focusing this technology on the car phone. Cooper wanted people to have freedom to talk on the phone away from their cars. So in reaction, he and Motorola embarked on a project to create a more portable device.
