In the late 1940’s and early 1950’s, DuMont was America’s fourth television network, competing with CBS, NBC and ABC. DuMont was second to enter the network TV business, establishing a link between its New York City and Washington, D.C. stations in 1945.
The DuMont network was the product of DuMont Laboratories, founded by Dr. Allen B. DuMont, “The Father of Television.” DuMont developed the first long-lasting cathode ray tube, the basis of electronic television, and was first to offer a home television receiver to the public in 1939 at the New York World’s Fair.
From 1949 to 1955, one of the most popular shows on DuMont (which in New York was Channel 5) was Captain Video and His Video Rangers (The Secret Files of Captain Video).
Set in the distant future, the series followed the adventures of a group of fighters for truth and justice, the Video Rangers, led by Captain Video. The Rangers operated from a secret base on a mountain top. Their uniforms resembled US Army surplus with thunderbolts sewn on.
