Motorola is an American telecommunications company best known for its cell phone and Bluetooth technology. In the company's early history they produced car radios, which helped to shape the origin of their name. Company founders Paul and Joseph Galvin felt the name helped to personify sound in motion. Once a leading manufacturer of cell phone handsets, Motorola has seen sales decline due to heavy competition from rivals like Nokia. In addition to their handset products, the company also produces semi-conductors and cell phone infrastructure hardware.
