Motorola was the first company to produce a handheld mobile phone. On 3 April 1973, Martin Cooper, a Motorola researcher and executive, made the first mobile telephone call from handheld subscriber equipment, placing a call to Dr. Joel S. Engel of Bell Labs.

This way, cell phones have been around for a little more than 40 years. Such a device as a mobile phone may be considered one of the most rapidly developing concepts of the high-tech industry.
