Английская Википедия:DuMont Laboratories
Шаблон:Short description Шаблон:Commons category Шаблон:Infobox company Allen B. DuMont Laboratories, Inc.[1] (printed on products as Allen B. Du Mont Laboratories, Inc., commonly referred to as DuMont Laboratories, shortened to DuMont Labs; referred to on company documents as DuMont) was an American television equipment manufacturer and broadcasting company. At one point it owned TV stations WABD (now WNYW; FOX O&O), KCTY (defunct; DuMont affiliate), W2XVT (experimental; defunct; DuMont affiliate), KE2XDR (experimental; defunct; DuMont affiliate), & WDTV (now KDKA-TV; CBS O&O), as well as WTTG (FOX O&O), all former affiliates of its defunct DuMont Television Network.
The company was founded in 1931, in Upper Montclair, by inventor Allen B. DuMont, with its headquarters in nearby Clifton. Among the company's developments were durable cathode ray tubes (CRTs) that would be used for TV and its magic eye tube.[2]
History
In 1938, DuMont Labs began manufacturing televisions at a factory in nearby Passaic, New Jersey.[2]Шаблон:Rp To sell TVs, it began the DuMont Television Network in 1942, one of the earliest TV networks. Later, they manufactured cameras and transmitters for TV. DuMont equipment was known for its high quality. The main CRT factory was in Clifton, New Jersey. It made black and white TV tubes as well as instrumentation and military fire control tubes in the early 1950s.
In 1956, under the ownership of Paramount, DuMont Labs shuttered the network and spun off WABD & WTTG to "DuMont Broadcasting Corporation". Eventually, the company was renamed "Metropolitan Broadcasting Company" in order to distance itself from the DuMont branding, which was seen as a failure. In 1958, John Kluge bought Paramount's stake in Metropolitan Broadcasting, renaming it to Metromedia.[2]Шаблон:Rp DuMont's partner, Thomas T. Goldsmith, remained on Metromedia's board of directors until the stations were sold to the Fox Television Stations Group. Nearly every original DuMont television program is considered lost, and presumed destroyed. Only roughly 100 recordings of any DuMont series have been recovered.[4]
DuMont Labs eventually sold its TV manufacturing division to Emerson Radio in 1958. The remainder of the company merged into Fairchild Camera in 1960.[2]Шаблон:Rp Fairchild later developed semiconductor microchips. Robert Noyce, founder of Intel, originally worked for DuMont Labs as an engineer.
DuMont Labs TVs outside the US were assembled under license in Montreal, Quebec, Canada by Canadian Aviation Electronics, currently a manufacturer of flight simulator and pilot training equipment.
