| 40 years ago the first cellular phone was invented by Martin Cooper of Motorola ... and it was almost the size of a shoe box |
This year marks 40 years since the first public cellular phone call was made by Martin Cooper of Motorola. This mobile phone was a massive device by today's standards – weighing two and a half pounds (1.15 kg) and all of 10 inches long it could only be used for 20 minutes before the battery died.
