Additional history:
CBS's first television broadcasts were experimental, often only for one
hour a day, and reaching a limited area in and around New York City. To
catch up with rival RCA, CBS bought Hytron Labratories in 1939, and
immediately moved into set production and color broadcasting. Though
there were many competing patents and systems, RCA dictated the content
of the FCC's technical standards, and grabbed the spotlight from CBS,
DuMont and others by introducing television to the general public at the
1939 New York World's Fair. The FCC began licensing televsion stations
on July 1, 1941; the first license went to RCA and NBC's WNBT; the
second license, issued that same day, was to WCBS. CBS-Hytron offered a
practical color system in 1941, but it was not compatible with the
black-and-white standards set down by RCA. In time, and after
considerable dithering, the FCC rejected CBS's technology in favor of
that backed by RCA.
CBS-Hytron manufactured point-contact transistors initially . They
dropped the "Hytron" for their first junction types. |
