Brief History Of Television (The Birth of Television / TV))

Beraudiovisual's friends, in this article I'll discuss a bit about the history of television (TV). You all must have a television at home. But do you know how the early history of television itself? 

In 1873 a telegraph operator from Valentia, Ireland, named Joseph May found that "the light affects the electrical resistance of selenium." He realized it could be used to convert light into electrical current by using a photocell silenium (selenium photocell). Joseph May along Willoughby Smith (technician from the "Telegraph Construction Maintenance Company") do some further experiments reported in the "Journal of the Society of Telegraph Engineers". This is the beginning of the image recording technology. 

After some time, then created a small metal plate that can rotate with holes in it, by a student named Paul Julius Gottlieb Nipkow (1860-1940) or better known as Paul Nipkow in Berlin, Germany, in 1884 and referred to as the forerunner to the birth of television. Around 1920 John Logie Baird (1888-1946) and Charles Francis Jenkins (1867-1934) used the work of Paul Nipkow disc to create a system of image capture, transmission, and reception. They make the entire television system is based on the mechanical motion systems, both in broadcasting and reception. At that time undiscovered electrical components vacuum tube (Cathode Ray Tube) 

In those days, the development of electronic television experience obstacles in its development. This is because television is more expensive mechanical and resilient. Other obstacles are very difficult to obtain financial support for research on electronic TV when the TV mechanic considered able to work very well at that time. No registration until Vladimir Zworykin (1889-1982) and Philo T. Farnsworth (1906-1971) managed by the electronic TV. With low cost and the results went well, then people at the time it gradually began to leave the TV mechanics and replace them with electronic TV. 

Vladimir Zworykin, who was one of several experts in those days, had help from David Sarnoff (1891-1971), Senior Vice President of RCA (Radio Corporation of America). Sarnoff has been a lot of very concerned about the development of mechanical television, and electronic TV would have predicted the future a better commercial. Moreover, Philo Farnsworth also managed to get sponsors to support the idea and took to compete with Vladimir.

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. Their main competitors are the Baird Television, which was first broadcast since 1928, using entirely mechanical system. At that very few people have televisions, and they have generally modest quality. In those days the TV screen size is only about three to eight inches just so mechanical and electronic competition is not so obvious, but the competition was there. 

RCA TV, TT5 Type 1939, RCA and Zworykin ready for a regular TV program, and they demonstrate on a large scale at the World Fair in New York. Enthusiastic people who are so greatly to this electronic system, causing "the National Television Standards Committee" [NTSC], 1941, decided it was time to standardize the transmission of television broadcast system in America. Five months later, all American television stations, amounting to 22 item, already convert the system into the new electronic standard. 

In the first years, while world economic recession, the price of a television set is very expensive. When prices began to fall, the American second world war. After the war, television included in the golden era. Unfortunately in those days all people can only see it in black and white format.

CBS actually had more first build color system a few years before his rival RCA. But their systems are not compatible with most black and white TV in the entire country. CBS has spent a lot of cost for the color they should be aware of the fact that their job ends in vain. Learning from the experience of CBS, RCA began to build a color system according to its own format. They quickly create a color system that is able to be accepted in black and white or color systems. After the RCA demonstrated the ability of their systems, the NTSC format and then used as a reference standard for commercial broadcasting in 1953. 

As time goes by and the development of technology, television from time to time start a lot of improvements and additions in terms of technology. For television the next time slowly began to leave the analog technology and stepped into an era that is called digital television with the ability and better quality than the previous generation of technology commonly known as IPTV [Internet Protocol Television]. 

That is a brief history of television. Hopefully Beraudiovisual's friends got a lot of knowledge after reading it.
