The 1st Invention
In 1873 Joseph May a telegraph operator from Valentia, Ireland found the light affects electric selenium resistance. He realized that can be used to change the light into electric current using a selenium photocell. Joseph May with Willoughby Smith (engineers from Telegraph Construction Company Maintenance) to do some further experiments that are reported in the Journal of the Society of Telegraph Engineers.
After some period of time then ever found a small metal plate that can rotate with holes in it by Paul Julius Gottlieb Nipkow (1860-1940) or better known Paul Nipkow in Berlin, Germany at 1884 and referred to as the embryo of the birth of television. Around 1920 John Logie Baird (1888-1946) and Charles Francis Jenkins (1867 – 1934) using the Paul Nipkow’s disc to create a system in the arrest of a picture, transmission, and receive. They make the whole system is based on the television system mechanical movement, both in broadcasting and receive.
Electronic television rather stagnating development in the early years, the more mechanical television was due to cheaper and more resistant rock. Not only that, but also very difficult to get financial support for research electronic TV when TV mechanics are considered able to work with very well at that time. Until finally Vladimir Kosmo Zworykin (1889-1982) and Philo T. Farnsworth (1906-1971) succeeded to the electronic TV. With the cheap cost of running well and the result, the people at the time it gradually began to leave the TV and replace it with a mechanical electronic TV.
