Histroy of television The development of the television

occurred over a number of years, inmany countries, and using a wide

application of sciences, includingelectricity, mechanical engineering,electromagnetism, sound technology,and electrochemistry

Sir William Crookes invented thecathode ray tube in 1878, but thesediscoveries took many years tomerge into the common ground oftelevision.

Paul Nipkow of Germany made thefirst crude television in 1884 . Hismechanical system used a scanningdisk with small holes to pick upimage fragments and imprint them

on a light-sensitive selenium tube

John Logie Baird of Scotland andCharles F. Jenkins of the UnitedStates constructed the first true

television sets in the 1920s bycombining Nipkow's mechanicalscanning disk with vacuum-tubeamplifiers and photoelectric cells

To the surprise of most people, television

transmission began almost 25 years beforethe end of World War II. John Logie Baird, inEngland, and C. Francis Jenkins, in the UnitedStates, both made public demonstrations oftelevision in 1925. Unlike post-war electronic

televisions, these early systems usedmechanical scanning methods.

Jenkins publicly broadcast moving imageswith his equipment in 1925. His first 10-

minute broadcast showed in silhouette themotions of a small operating windmill. By1931, he had experimental televisionstations operating in New York and

Washington
