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.

Mitchell successfully pushed Motorola to develop wireless communication products that would be small enough to use anywhere and participated in the design of the cellular phone.

Because phones have become mobile media devices, the most desirable aspect is a large, clear, high-definition screen for optimal web viewing. Even the keyboard is being taken away, replaced by a touch screen keyboard that only comes out when you need it. The most obvious example of this is the Apple iPhone
