History of Television

Television is no longer a luxury for most people in the world. Almost all homes have this one thing. Various TV stations broadcasting with various programs presented with the picture quality and sound are slick, making television as a source of all information, news, and entertainment that takes us all.

The beginning of the discovery of television would not be separated from the basic discovery, namely Electromagnetic Waves law discovered by Joseph Henry and Michael Faraday (1831) which is the beginning of the era of electronic communication. In 1873 a telegraph operator discovered that light affects the electrical resistance of selenium. He realized it could be used to convert light into electrical current using a photocell silenium (selenium photocell) Then a student named Paul Nipkow in Berlin, Germany in 1884 discovered a small metal disc rotating with holes in it and is referred to as embryo birth of television.

Around 1920 John Logie Baird and Charles Francis Jenkins using the work of Paul Nipkow disc to create a system in image capture, transmission, and reception. In 1923 Vladimir Zworykin Kozma, register a patent in his name for his invention, kinescope, the world's first television tubes. Zworykin openness to criticism, again making new discoveries ie a camera tube called iconoscope. He was later referred to as the inventor of television. (1889-1982).

ELECTRONIC

Electronic television rather stagnant development in those years, this was due to less mechanical television and hardiness. Until Kosmo Vladimir Zworykin and Philo T. Farnsworth managed to find electronic TV. Both Farnsworth, and Zworykin, working separately, and both succeeded in making progress for a TV commercial with a very affordable cost.

In 1935, they began to broadcast using a fully electronic system. But unfortunately at that time all the people can only see it in black and white format. In those days the TV screen size is only about three to eight inches so the competition mechanics and electronics are not so real.

Decades later to the beginning of the 21st century, people are used to talking on a mobile phone and digital sending e-mail through the computer network world, but television technology at its core remains the same.

Of course there are a few developments such as stereo sound and a better color, but there is a big leap that is able to shake up our perceptions of television.
