Color Television History
Call it an 'idiot box' but mind you, the truth remains, that the Television is an integrate part of our lifestyle. Technology advancement has provided us many sources of entertainment but the Television has its own importance.
The history of Television is enriched with the contributions of many inventors across the world. Every minuscule role counts! The black and white Television sets sold up to a million in a short period and the switch to a color Television was as well a big welcome.
From mini screen to Home theatres, from manual operations to 'Remote control', the television has undergone tremendous improvements since its dawn in the early nineteenth century.
Evolution of the Television
- Minor change in the synchrony among the signal and disk motor caused the image to get distorted.
- There was an imbalance between the image size and the screen.
- The most primitive form of Television was based on the mechanism of holes punched on a spinning disk (called as Nipkow disk); the spots would in turn scan the images but the major problem associated was that of the resolution which was poor.
- The mechanical systems (that used rotating disks) developed during the early times were replaced by the electronic television systems (that used Cathode tube).
- In 1950s the remote controllers gained an entry into the US homes.
- Porta-color was the first known brand of portable color television, launched by General Electricity somewhere between 1960s and 1970s.
- The late nineteenth century saw more advances like the Home theatre, the Plasma Television etc.
Invention of Television
Progress of mechanical system:
- Paul Nipkow, the legendary German scientist made use of the scanning principle in a rotating disk technology to transmit images. This laid the basic foundation in the making of a television.
- John Logie Baird (made use of group of clear rods to transmit images) and Charles Jenkins (discovered a system called radio vision) are in the records for modifying the primitive mechanical television. He also developed the world's first color transmission and the first color broadcast which turned out to be a remarkable evolution in the history of televisions.
Moving steps forward - from mechanical to electronic system:
- An electro-mechanical system was designed by Peter Goldmark that made use of an Iconoscope sensor.
- Karl Braun, a German scientist, invented the cathode ray tube and took the progress of television system to the electronic stage that overcame most of the drawbacks associated with the mechanical system.
- Zworykin, a Russian scientist, invented the Kinescope, which turned to be a vital requirement in the television system. The make of the Television was almost the same as that of modern televisions.
- Farnsworth constructed the dissector tube on which modern Televisions are built upon.
- Louis Parker patented the unfixed television receiver.
- The credit of discovering the V-shaped Television antennae has been conferred upon Marvin Middlemark.
When was the first color television introduced?
The history of invention of color Television goes parallel with the progress of Black and White television. By no means can it be said that color television is a late discovery!
- Patents of having created a color Television in the early nineteenth century are in the record. The concept of color televisions has been worked since the times Black and White Television systems had been launched.
- Records reflect the name of inventor, Maurice Blanc, for proposing the concept of color television in the 1880s. Zworykin patented discovery for an electronic color television system, which did not work wells. The Dot-sequential color systems came into being using signals similar to the Black and White systems.
- The first color Television was successfully launched under the right of FCC in the 1950s, prior to which CBS (lost the market due to Korean War) and RCA had attempted to design the color system. RCA designed a better Television which was launched in the market and gained commendable response and in the 1970s the sales overtook Black and White sets.
First color television show
- NBC TV was the pioneer in launching the first color Television shows like "The Colgate Comedy Hour", a live Broadcast of the president, Popular Cartoon films etc. The Disney created a big boom in the cartoon series.
The history of color Television is indeed remarkable. Our day begins with the Television and ends with it, the fact which cannot be denied. Needless to say the progress has not come to a halt in the field of Television systems; there is more to experience in the coming future.
