Philco

Philco (an acronym for Philadelphia Battery Company)is an American electronics manufacturer headquartered in Philadelphia. Philco was a pioneer in battery, radio, and television production. In 1961, the company was purchased by Ford and, from 1966, renamed "Philco-Ford". Ford sold the company to GTE in 1974, and it was purchased by Philips in 1981. In North America, the Philco brand is owned by Philips. In other markets, the Philco International brand is owned by Electrolux. In the early 1920s, Philco made storage batteries, "socket power" battery eliminator units (plug-in transformers), and battery chargers. With the invention of the rectifier tube, which made it practical to power radios by electrical outlets, in 1928, Philco entered the radio business. They followed other radio makers such as RCA, Atwater-Kent, Zenith Electronics, Freshman Masterpiece, FADA Radio (Frank A. D'Andrea Radio), and AH Grebe into the battery-powered radio business. By the end of 1930, they were selling more radios than any other maker, a position they held for more than 20 years. Philco built many iconic radios and television sets, including the classic cathedral-shaped wooden radio of the 1930s (aka the "Baby Grand"), and the Predicta series of television receiver sets of the 1950s. Philo Farnsworth, credited for inventing the first fully functional all electronic vacuum tube television system (, filed Jan 7, 1927), worked at Philco from 1931 to 1933. Philco was founded in 1892 as Helios Electric Company. From its inception until 1904, the company manufactured carbon-arc lamps. As this line of business slowly foundered over the last decade of the 19th century, the firm experienced increasingly difficult times. As the Philadelphia Storage Battery Company, in 1906 it began making batteries for electric vehicles. They later supplied home charging batteries to the infant radio industry. The Philco brand name appeared in 1919. From 1920 to 1927, all radios were powered by storage batteries which were fairly expensive and often messy in the home.
