Who developed television?

Answer 1

There were many people involved in the development of television: Philo Farnsworth Vladimir Zworykin David Sarnoff John Logie Baird This is only a partial list of the people involved. RCA and EMI-Marconi built some of the equipment used for early TV broadcasting. I believe other countries were working on television in the 1930's but I don't have the info on their operations. The BBC started limited TV broadcasting three years before the US did. The BBC Television Service in 1936 and RCA/NBC in 1939. Regular TV broadcasting began on a large scale after World War 2.

Answer 2

Philo realized an electron beam could scan a picture in horizontal lines, reproducing the image almost instantaneously. It would prove to be a critical breakthrough when he was 14 years old and working in a farm. At the same time, Russian immigrant Vladimir Zworykin had also designed a camera that focused an image through a lens onto an array of photoelectric cells coating the end of a tube. The electrical image formed by the cells would be scanned line-by-line by an electron beam and transmitted to a cathode-ray tube.In 1934, the British communications company British Gaumont bought a license from Farnsworth to make systems based on his designs. In 1939, the American company RCA did the same. Both companies had been developing television systems of their own and recognized Farnsworth as a competitor.
