William Lear collaborated with friend Elmer Wavering to build the first practical car radio and decades later invented and marketed the automotive 8-track tape format, which built the modern car stereo industry on the foundation created by Hall of Fame member Earl Muntz. Lear's radio served as the design for the first practical mass-produced car radio, built in 1930 and marketed by the Galvin Manufacturing Co. under the Motorola brand name. In 1963, Lear bought Muntz 4-track car tape players to install in the business jets that bore his name. Looking for a simpler, longer-playing system, Lear devised and patented the 8-track format. Motorola, then a maker of car radios, adopted the format early followed by RCA Consumer Electronics and its sister company RCA Records, and soon after, other companies. In 1966 Ford was the first to offer an in-dash radio-8-track combination as a factory installed option. The 8-track format was the dominating format for pre-recorded music on tape into the early 1980s, when advances in tape technology and noise reduction made the compact cassette the system of choice.
