Currently, cell phones are commonplace to see every day, it was extremely rare that you saw a person with a mobile phone 40 years ago, in fact, wireless communication available to all staff and virtually non-existent at that time, the cases worldwide were very few, and here we see the first.
It was on April 3, 1973 when Martin Cooper of Motorola showed his great invention to the world. He was in the village of New York City when he made the first phone call in history through the working prototype of a mobile, the DynaTAC. Who called in that historic moment Mr. Cooper? When President Nixon?? Does your boss perhaps? Of course not, he called Joel Engel, his rival at AT & T, who was also working on the technology of mobile phones in those days.
Of course, the DynaTAC, also known as "the brick", just hit the market a decade later. It weighed just over 1 kilogram and 10 hours of charging only let us talk 30 minutes maximum.Obviously cellular calls were extremely expensive, so insurance would not talk for more than a minute. In fact, the phone itself cost about $ 9000 today.
Today cell phones are small, very cheap and also calls are cheap, not to mention phone technology, which is much more advanced.
