In what year was the mobile phone invented?

In 1946 there was a small number of car phone services begun in St Louis, Missouri, USA.

In 1973 the first successful hand-held mobile phone was developed by Martin Cooper.

Dr Martin Cooper, a former general manager for the systems division at Motorola, is considered the inventor of the first modern portable handset. Cooper made the first call on a portable cell phone to his rival, Joel Engel, head of research at Bell Laboratories.

Bell had introduced the idea of cellular communications in 1947 with their police car technology and had been racing to beat Motorola. But in the end Motorola was first to incorporate the technology into a portable device designed for use outside a vehicle.

The first really portable phone for the general public was produced in 1985 by Vodaphone.
