The History of Television
The history of television began in 1926 when John Logie Baird from Scotland
demonstrated the first public electronic TV. It wasn’t until the next year that
Bell Telephone and AT&T introduced the first TV to America. Before 1935, it was
called the “Mechanical Television Era”. The picture was a blurry orange-red
electronically produced with a spinning disc and was very tiny.
The next phase
The age of TV was born but had a long road ahead. The first TV set sold in
America was the 1938 Du Mont Model- 180 which sold for $395! Only four of these
early TV sets are believed to still exist. In the 1930’s, Manufacturers like GE,
RCA, Du Mont, Baird, Andrea built the early
electronics sets inside handcrafted
wood cabinets to match the consumers’ home. By the Forties and Fifties, new
televisions by new companies like Emerson, Motorola, and Zenith joined the fray.
The greatest change was developed in the 1950’s when both the electronic color
TV and TV remote control were introduced.
Early milestones of the TV history include;
- Paul Gottlieb Nipkow developed a rotating-disc technology to transmit pictures
over wire in 1884 called the Nipkow disk, the very first electromechanical TV
scanning system. It was abandoned early in the history of TV for the electronic
systems developed by later inventors.
- John Logie Baird is remembered as being an inventor of mechanical television,
an earlier version of TV that was discontinued. It was developed in late 1920s
in England. During W.W.II, Baird developed the first color picture tube.
- Charles Francis Jenkins contributed to the development and promotion of
mechanical television in Britain, and invented a mechanical television system
called radiovision. He claimed to have transmitted the earliest moving
silhouette images on June 14, 1923.
- German scientist, Karl Braun invented the cathode ray tube oscilloscope (CRT)
in 1897.
- Vladimir Kosma Zworykin invented the cathode-ray tube called the kinescope in
1929, a tube needed for TV transmission and the iconoscope, an early television
camera.
- Philo T. Farnsworth conceived the basic operating principles of electronic
television at the age of just 13 years and created patent drawings.
By 1953, 300 000 televisions were being built in
the United States alone. As the TV sales grew, so did the emerging TV networks
ABC, NBC and CBS. In the early Sixties and Seventies, Japanese TV manufacturers
Sony, Panasonic, JVC and Toshiba
were imported to the U.S.A. The Japanese dominance of consumer electronics had
begun.
Today, new electronic technologies are changing the market from the CRT
televisions to plasma televisions, LCD televisions (Liquid Crystal Display), DLP
(Digital Light Projector) projection TVs. The signals from the TV networks are
getting better as well. As the older NTSC system is slowly disappearing, the new
ATSC or more commonly known as HDTV (High Definition TV) will be the main TV
provider for the years to come.
