After a long period of time and then created a small metal disc that can rotate with the holes in it by a student named Paul Julius Gottlieb Nipkow (1860-1940), better known Paul Nipkow in Berlin, Germany in 1884 and referred to as the embryo the birth of television. Around 1920 John Logie Baird (1888-1946) and Charles Francis Jenkins (1867-1934) using the work of Paul Nipkow disc to create a system in the image capture, transmission, and reception. They make the whole television system is based on mechanical motion systems, both in broadcasting and reception. At that time undiscovered electrical components vacuum tube (Cathode Ray Tube)
Rather stagnant development of electronic television in those years, mostly due to less mechanical television and resilient. Not only that, but also very difficult to get financial support for research on electronic TV when the TV mechanic is considered able to work very well at that time. Kosmo until Vladimir Zworykin (1889-1982) and Philo T. Farnsworth (1906-1971) succeeded to the electronic TV. With the low cost and the results are going well, then the people at that time gradually began to leave the tv mechanic and replace it with electronic tv.
Vladimir Zworykin, who was one of several experts at the time, enlisted the help of David Sarnoff (1891-1971), Senior Vice President of RCA (Radio Corporation of America). Sarnoff has devoted much attention to the development of mechanical television, and electronic TV foresee the future will have a better commercial. Moreover, Philo Farnsworth also managed to get a sponsor to support the idea and compete with Vladimir.
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 broadcasts using a fully electronic system. Their main competitor is the Baird Television, which was first broadcast in 1928, using a mechanical system entirely. At that time very few people who have a television, and that they have generally modest quality. At that time the screen size of the TV is only about three to eight inches so that the mechanical and electronic competition is not so obvious, but the competition is there.
RCA TV
RCA TV, TT5 Type 1939 RCA and Zworykin ready for regular TV program, and they demonstrate massively at the World Fair in New York. Enthusiastic people who are so big on the electronic system, causing the National Television Standards Committee [NTSC], in 1941, decided it was time to standardize the transmission of television broadcast system in America. Five months later, all American television stations totaling 22 pieces, is convert the system into the new electronic standard.
In the early years, while the world economic recession, the price of a television set is very expensive. When prices began to fall, American second world war. After the war, television entered the golden era. Unfortunately at that time everyone can just see it in black and white format.
COLOR TV
CBS has actually build the system first color RCA several years before its rivals. But those systems are not compatible with most black and white TV throughout the country. CBS has issued a lot of cost for their color system must recognize the fact that their job ends in vain. Learning from the experience of CBS, RCA began to build the color system according to its own format. They quickly made a color system that is able to be accepted in color or black and white system. After RCA demonstrated their system capabilities, NTSC format and then used as a reference standard for commercial release in 1953.
As time goes by and the development of technology, the television from time to time many improvements and additions ranging from the technology side. For next time slowly began to leave technology television analog and stepped into the era of the so-called digital television with the capability and better quality than previous generation technology commonly known as IPTV [Internet Protocol Television].
