Motorola started as Galvin Manufacturing Corporation in 1928. The name Motorola was adopted in 1947, but the word had been used as a trademark since the 1930s. Founder Paul Galvin came up with the name Motorola when the company started manufacturing car radios. He created the name “Motorola” to suggest sound in motion (from “motor” and the then-popular suffix “ola”). The Motorola brand name became so well-known that Galvin Manufacturing Corporation later changed its name to Motorola, Inc. Many of Motorola's products have been radio-related, starting with a battery eliminator for radios, through the first walkie-talkie in the world, defense electronics, cellular infrastructure equipment, and mobile phone manufacturing. The company was also strong in semiconductor technology, including integrated circuits used in computers. Motorola has been the main supplier for the microprocessors used in Commodore Amiga, Apple Macintosh and Power Macintosh personal computers. The chip used in the latter computers, the PowerPC family, was developed with IBM and in a partnership with Apple (known as the AIM alliance). Motorola also has a diverse line of communication products, including satellite systems, digital cable boxes and modems.
