At the dawn of television history there were two distinct paths of technology experimented with by researchers.Early
inventors attempted to either build a mechanical television system
based on the technology of Paul Nipkow's rotating disks; or they
attempted to build an electronic television system using a cathode ray
tube developed independently in 1907 by English inventor A.A.
Campbell-Swinton and Russian scientist Boris Rosing.
Electronic television systems worked better and eventual replaced mechanical systems.
Paul Gottlieb Nipkow - Mechanical Television History
German, Paul Nipkow
developed a rotating-disc technology to transmit pictures over wire in
1884 called the Nipkow disk. Paul Nipkow was the first person to
discover television's scanning principle, in which the light intensities
of small portions of an image are successively analyzed and
transmitted.
John Logie Baird - Mechanical
In
the 1920's, John Logie Baird patented the idea of using arrays of
transparent rods to transmit images for television. Baird's 30 line
images were the first demonstrations of television by reflected light
rather than back-lit silhouettes. John Logie Baird based his technology
on Paul Nipkow's scanning disc idea and later developments in
electronics.
Charles Francis Jenkins - Mechanical
Charles Jenkins
invented a mechanical television system called radiovision and claimed
to have transmitted the earliest moving silhouette images on June 14,
1923.
Cathode Ray Tube - Electronic Television History
Electronic television is based on the development of the cathode ray tube, which is the picture tube found in modern TV sets.
German scientist, Karl Braun invented the cathode ray tube oscilloscope (CRT) in 1897.
Vladimir Kosma Zworykin - Electronic
Russian inventor, Vladimir Zworykin
invented an improved cathode-ray tube called the kinescope in 1929. The
kinescope tube was sorely needed for television. Zworykin was one of
the first to demonstrate a television system with all the features of
modern picture tubes.
Philo T. Farnsworth - Electronic
In
1927, Philo Farnsworth was the first inventor to transmit a television
image comprised of 60 horizontal lines. The image transmitted was a
dollar sign. Farnsworth developed the dissector tube, the basis of all
current electronic televisions. He filed for his first television patent
in 1927 (#1,773,980).
Louis Parker - Television Receiver
Louis Parker invented the modern changeable television receiver. The patent was issued to Louis Parker in 1948.
Rabbit Ears - Antennae
Marvin
Middlemark invented "rabbit ears", the "V" shaped TV antennae. Among
Middlemark's other inventions were a water-powered potato peeler and
rejuvenating tennis ball machine.
Color Television
Color
TV was by no means a new idea, a German patent in 1904 contained the
earliest proposal, while in 1925 Zworykin filed a patent disclosure for
an all-electronic color television system. A successful color television
system began commercial broadcasting, first authorized by the FCC on
December 17, 1953 based on a system invented by RCA.
History of Cable TV
Cable
television, formerly known as Community Antenna Television or CATV, was
born in the mountains of Pennsylvania in the late 1940's. The first
successful color television system began commercial broadcasting on
December 17, 1953 based on a system designed by RCA.
Remote Controls
It
was in June of 1956, that the TV remote controller first entered the
American home. The first TV remote control called "Lazy Bones," was
developed in 1950 by Zenith Electronics Corporation (then known as
Zenith Radio Corporation).
Origins of Children's Programming
The American Broadcasting Company first aired Saturday morning TV shows for children on August 19, 1950.
Plasma TV
The very first prototype for a plasma display monitor was invented in 1964 by Donald Bitzer, Gene Slottow, and Robert Willson.
History of Closed Captioning TV
TV closed captions are captions that are hidden in the television video signal, invisible without a special decoder.
Web TV
Web TV was rolled out in 1996.
