The inventor of the cell phone is an employee of the company ‘Motorola’ Martin Cooper. He invented the first cell phone in 1973. The phone weighed more than 1 kg and was later called Motorola DynaTAC. The phone had 12 buttons, 10 of which were digital, the other two were used to start and end the call.
The phone didn’t have a display. The battery lasted not more than an hour and it took 10 hours to charge.
The first cell phones began to be mass produced in 1983 under the name DynaTAC 8000х. They cost 3995$. It was extremely expensive at that time, however, a lot of people wanted to buy one.
