Cell phone evolution

Prior to 1973, mobile telephony was limited to phones installed in cars and other vehicles.
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.

Because phones have become mobile media devices, the most desirable aspect is a large, clear, high-definition screen for optimal web viewing.
