Actually, DuMont did some pioneering stuff back in the day. Our first TV was a DuMont.
A series of Web pages devoted to the DuMont Television Network, America’s fourth television network which operated from 1946 to 1956. After searching for such a page for some time, the author decided to fill the void himself by creating a site devoted to DuMont. This was the first, and is still the largest, DuMont resource on the Internet.
As I presume the history site explains, DuMont ceased network operations and their TV operations morphed into a group called Metromedia. WABD New York became WNEW.
Eventually, Rupert Murdoch bought the former DuMont stations and formed the nucleus of the Fox Network. WNEW became today’s WNYW.
So the original “fourth” network resurrected to become the present-day fourth network.
DuMont’s nephew is Chicagoan Bruce DuMont, who hosts the syndicated Sunday radio talk show “Beyond the Beltway.”
