Nipkow disk
Nipkow Disk Paul Nipkow designed the very first television scanning device. He descovered televisions scanning priniciple, in which light intesities of a small portion of an image are successively analyzed and transmitted. The Nipkow disk is a rotating disk that has holes in it which allow light to pass through, creating a rectangular electrical signal -
cathode ray tubes
cathode ray tubeBesides television sets, cathode ray tubes are also used in computer monitors, automated teller machines, video game machines, video cameras, oscilloscopes and and form of radar displays. The very first cathode ray tube scanning device was invented by Karl Ferdinand Braun. He ivented the cathode ray tube with a fluerecent screen known as the cathode ray oscilloscope.

First mechanical television system
30 rod imageA man named John Baird created the very first actual mechanical television system. He used arrays of transparent rods to transmit images for television. This image was a 30 lined image that created a blured image of reflected light through the rods.This was the first demonstration of television.Baird based his idea off of paul nipkows Nipkow Disk. The image you see is what the image looks like from the rod -
iconoscope
iconoscopeZworykin also invented the iconoscope which is a tube for television transmission used in the first cameras.this came before the kinescope was invented, so this was his first idea. The iconoscope was later replaced but it laid the foundations for early television cameras. -
Radiovision
RadiovisionCharles Jenkins invented a mechanical television system called radiovision and claimed it to have transmitted the earliest moving images on June 14, 1923. Charles Jenkins publicly performed his first television broadcast, from Anacosta, Virginia to Washington in June, 1925. He had been researching mechanical television since1894. -
dissector tube.
dissector tube Philo Farnsworth was the first inventor to transmit a television image comprised of 60 horizontal lines rather than 30. The image transmitted was a dollar sign. Farnsworth developed the dissector tube, the basis of all current electronic televisions. -
The very first television company

They sold thousand of radiovision sets to people from prices between $85 and $135. Mainly only rich people were able to afford this back then. -
kinescope
kinoscopeVladimir Zworykin invented the cathode-ray tube called the kinescope in 1929. The kinescope tube was sorely needed for television back then. This invention was a more advanced version of the iconoscope. Zworykin was one of the first to demonstrate a television system with all the features of modern picture tubes, which was previously called the cathode-ray tube. His invention later lead to the existence of RCA (his television company im America). -
Television Reciever
television recieverLouis W. Parker's television receiever is now used in all television receivers in the world. Without it television receivers would not work as well and would be more costly. It's basically just the basic sound system found in all televisions. -
Cable TV
Cable Tv
Community antenna television (now called cable television) was started by John Walson and Margaret Walson. Cable television was originaly knows as Community Antenna Television or CATV, but is now just called cable. John Walson connected a mountain antennae to both his store and several of his customers' homes that were located in the are starting the nation’s first CATV system -
Remote Contorol
remote control

It turned out that consumers did not like the cable because it caused frequent tripping. -
The First Color Television
Color TelevisionA successful color television system began commercial broadcasting, first authorized by the FCC on December 17, 1953 based on a system designed by RCA. Their were two previous designs that were not succesful, however they went down as attempts. Most tvs were still in black and white and only the richest peoplew were able to have a color tv. -
first plasma display monitor
plasma tv It was not until after the invention of digital and other technologies that a successful plasma televisions became possible. The first two men who attempted were Donald Bitzer and Gene Slottow from the University of Illinios. After 1964, television broadcast companies considered developing plasma television as an alternative to televisions using cathode ray tubes -
web tv
WebTV was invented in 1996 by Diba Inc and Zenith Electronics, who produced and marketed the first WebTV sets. Basically a web tv is a tv set that can access the internet from the tv. The internet wasn't anything like what we have now, however this was a huge step in the tv industry. You had to of been very wealthy to have this kind of tv back in the 60's. -
