Television has fundamentally changed the life of mankind, giving access to daily news programs, feature films and entertainment programs. In terms of technology, television is the transmission of moving images at a distance. The idea of such an invention appeared in the XIX century, but the principle was implemented much later.
How did television come about?
The fundamental possibility of transferring moving pictures over a long distance was substantiated independently by the Portuguese A. di Paiva and the Russian scientist P. Bakhmetyev back in the late 19th century. The principle they proposed involved the conversion of images into electrical signals and their transmission through communication channels. At the opposite end of the line, the signal should again turn into an image.
Such an idea could only be realized with the help of relatively sophisticated electronic devices. This was done by the Russian scientist and inventor Boris Rosing when he invented in 1907 television based on a cathode ray tube.
The world's first image transmission in the form of simple figures was carried out by Rosing in Russia in May 1911.
The studies and works of the Russian scientist Vladimir Zvorykin, who was once a student of Rosing, were also widely known. Having emigrated to the United States during the Civil War, in 1923 Zvorykin created, and ten years later, introduced to the American public and the whole world an operating television system. Numerous works and inventions of Zvorykin in the field of black-and-white, as well as color television were awarded US awards.
The first television receiver available to the public appeared in England in the late 1920s.
