The Cell Phone is 40

  • by

It was 40 years ago (April 3, 1973) when Martin Cooper made his first call from his new Motorola DynaTAC cell phone.

I wonder if he knew he was doing something that would change the world. Cell phones have come a long way in the last four decades. They have gone from very bulky simple devices to some of the most sophisticated electronic devices in the world. And it fits in the palm of your hand. It’s actually quite difficult to think of a world without them.
