48 years ago, on April 3, 1973, the first mobile phone call was made. It was made by Motorola engineer Martin Cooper, who is considered the father of the mobile phone. He called his AT&T competitor, Joel Engel, and said, “Guess where I’m calling from? I’m calling you from a real cell phone. ”
For this, a portable cellular smartphone Motorola DynaTAC was used, which has little in common with modern smartphones. It had no display – only 12 keys. At the same time, it looked more like a brick with dimensions of 22.5 × 12.5 × 3.75 cm and weighing more than a kilogram. It was possible to talk on it for a little over 30 minutes, and it took about 10 hours to charge.
But Motorola DynaTAC went on sale only 10 years later – in 1983. And the price tag was simply exorbitant – almost 4 thousand dollars!
At the same time, the first touchscreen phones appeared in the late 90s.
