(The) Magnavox Company, Oakland, California, USA has moved to Fort Wayne (IN) when starting to manufacture radios in quantity. Magnavox was in San Francisco up to 1919. After it was bought by Philips it 1980 moved to Tennessee.

Founded: 1910

In 1910 Magnavox started as "Commercial Wireless & Development Company" at Napa, California. Peter L. Jansen, Edwin S. Pridham (both ex Federal Telegraph Company) and Richard O'Connor (finance) formed the company to achieve a sensitive telephone receiver. In 1915 Jensen and Pridham have put a horn to their "telephone receiver with moving-coil system" and then used it as a "Fog-Horn" for the local baseball park (Radio & TV News, February 1959). They called it Magna Vox. They developed a phonograph pickup and made a joint venture with Sonora in 1917 called "Commercial Wireless & Development Company".

They developed the "SE4005 noise-cancelling microphone" for aircraft intercoms. In 1919 Magnavox moved from 526 Mission Street, San Francisco to 14th Street in Oakland and made vacuum-tube power amplifiers. In February 1920 Magnavox introduced a radio speaker, forerunner of the 1921 Model R-3.

1924 Magnavox began also to produce a tube "A" with a special design and a year later also radios.
