TV was invented in 1920. The invention that swept the world and changed leisure habits for countless millions was pioneered by Scottish-born electrical engineer John Logie Baird. It had been realised for some time that light could be converted into electrical impulses, making it possible to transmit such impulses over a distance and then reconvert them into light. The first person on television was a boy who worked in the office next to Baird's workroom in London. A first-rate colour TV set and a video cassette recorder have become an ordinary thing in the household today. Regular translation of television programs began on 30 April 1939 in the United States, when President Franklin Roosevelt at the opening of the world fair in new York speech translation on television. There is virtually no family that does not have a TV set. Television plays a very important role in our lives. It is a powerful source of entertainment and information, a win door through which the whole world can enter our homes. (блин тут конечно не 20, ну самое главное я написала)
