The world's first television was made by John Logie Baird, a Scotsman living in England in 1925. He called it "The Televisor".
The screen was tiny, only a few inches across. Behind the screen was a spinning disc with holes punched through the disc. As the disc rotated, the holes passed across the screen, making 30 separate passes, from edge to edge. As the holes passed, a light behind the disc varied in brightness, so creating an image in the viewing area.
It was crude and the quality wasn't all that good. Nonetheless, it worked and the principle of drawing the image line by line has remained in use ever since. The quality has improved dramatically since that first demonstration and the rotating disc was replaced with electronics but Baird's invention hasn't changed all that much.
The first television system to be fully operational was the development of John Logie Baird in London in 1923. It was shown to the public in 1925.
It was a time of rapid advances in electrical engineering and two things were vital in the support of Baird's television. The first was the light sensitive device used to capture light levels and turn them into an electrical signal. Without this small component, no conversion of light to electricity could take place.
The second, and one that remains a fundamental part of television technology was the ability to break the image down into a stream of data that represented individual lines of the image. Baird used the Nipkow disc, invented by Paul Nipkow to capture printed images to an electrical signal. Unlike Nipkow, Baird used the disc to continuously capture an image and replay it using a similar disc at the receiver. It was this continuous scanning and replay that delivered a moving image for the viewer.
In later years, the CRT (cathode ray tube) replaced the spinning disc but the principle of a series of individual lines has persisted since Baird's first television.
A dude just stumbled accross one under an overpass in Television city in 1951. After that they just started turning up almost everywhere there was electric.
1929
it was first used in a factory
The duration of The First Lady - TV series - is 3000.0 seconds.
The duration of First Edition - TV series - is 1800.0 seconds.
Sony TV 8-301W was introduced in 1960 and was the first TV ever made by Sony.
The first television broadcast happened in 1926 and involved sending a still image from one room to another room. The first television station to broadcast was in 1941 and had the call letters of WNBT.

John Logi Baird, a scotsman, is often credited with the invention. However, he was one of many who worked on the development of television. There are many other names who contributed to the early television and it is probably better to refer to television as a development, rather than a single invention. A web search will produce many full histories of early television, from the first mechanical systems to the commercial broadcasts of the 1940s and 1950s.
tv, cz dat was the first invention for every one to lern for other invention EDIT: actually, computers are in almost everything. I should have done that for my paper but now i am stuck with the airplane! See, computers are in cell phones, cars, televisions, and airplanes, so it is fundamentally the most important! And the airplane came before the TV just so you know. The airplane was invented in 1903, actually. But automobiles were probably before that so i know TVs were not first. Computer was last.
The first television was shown to the world in 1925, approaching a century ago. It was the invention of John Logie Baird, a Scot working in England. The "Televisor", as he called it, really wasn't very good but Baird's work was remarkable nonetheless. The quality was limited by the technology of the time and of course, because Baird was the first to do it. There are many inventions that didn't work well. The process of development takes a raw invention and turns it into high quality and useful products. Baird's work paved the way for many other brilliant minds to improve the invention and so develop the televisions we watch today.
Likely the big invention between 1925 and 1935 was the television. It was first demonstrated to scientists in 1929 and to the public in 1939.

No, Jefferson died more than a century before the invention of television.
The development of this chip led to the invention of the first personal computer. With this invention, the use of computers spread from large businesses and the military to small businesses and homes.
the first invention during the industrial revolution was the flying shuttle
The first TV made by a southern Auatralian was probably put together from a kit. Television manufacturing, and the invention of the television, goes on (went on) elsewhere.
In his first attempts to develop a working television system, Baird experimented with the Nipkow disk, and in February 1924 demonstrated to the Radio Times that a semi-mechanical analogue television system was possible by transmitting moving silhouette images, such as his fingers wiggling, in his London laboratory. Baird gave the first public demonstration of moving silhouette images by television at Selfridges department store in London in a three-week series of demonstrations beginning on March 25, 1925.
Phiio Farnsworth was an inventor and a television pioneer. He contributed things that were crucial in the invention of the first electric TV. He held 165 patents.
