Mobile phone, complete with nickel cadmium battery, made by Motorola Inc, United States. The Motorola company was founded by Paul V Galvin as the Galvin Manufacturing Corporation, in Chicago, Illinois, in 1928. In the 1930s the company began promoting portable car radios under the brand name 'Motorola' (a word suggesting sound in motion), and the company name was eventually changed to Motorola, Inc in 1947. By the end of the 1980s, Motorola had become the biggest worldwide supplier of cellular telephones. The MicroTAC was followed in 1996 by the 3.1 ounce, pocket-sized StarTAC - the world's smallest phone.
