Founded: 1926
Closed: 1929

The National Union Radio Corporation was incorporated in September 1929 to acquire the assets of three radio tube manufacturers; Sonatron Tube Company; Televocal Corporation; and the Magnatron Corporation.  This merger occurred during a period in which the demand for radio tubes was extraordinary. Through much of the 1920s the demand for tubes had been primarily for use in radio sets, which by 1929 numbered over nine million due to the growth of the radio broadcast industry. Each of these sets used between three to twelve tubes. The result was that between 1927 and 1928 the number of tubes sold for use in radio sets alone grew 82.8 percent. There was also the expectation that tube sales would be furthered by their use in other electrical devices such as phonographs, talking movies, televisions, and long-distance telephones.

This manufacturer was suggested by Otmar Jung.
