Television Technology
Television technology was actually first developed in the 19th
century, before commercial radio was conceived of, when, in 1897,
Ferdinand Braun invented the cathode ray tube. The first time the
cathode ray tube was used to produce images was in 1907. The tube
was an essential step in the invention of television, followed by
Philo Farnsworth and Vladimir Zworykin's independent developments of
the image dissector and iconoscope.
Philo Farnsworth
By the end of the 1920s, the
United States had a total of fifteen experimental stations for
mechanical television. In 1929, Herbert Hoover, at the time the
Secretary of Commerce, made an appearance on the mechanical
television of AT&T.
RCA, the pioneer in broadcast development, did
broadcasting experiments in the early 1930s. On the eve of World War
II, RCA was pushing for its television standards to be accepted for
production. In response, the National Television System Committee,
created by the Federal Communications Commission (FCC) and composed
of engineers, made recommendations for electronic television system
standards. These were adopted in the spring of 1941.
World War II
delayed the commercial development of the television, although
research and development targeted for the war effort resulted in the
possibility of better products for consumers. At the close of World
War II, there were less than 7,000 working television sets, and only
nine stations on the air, in the entire country.
The United States
was the leader in television technology, primarily because advances
were made directly before, during and after WWII, when America's
major competitors in television development, Germany and England,
halted their research programs.
