TELEVISION
If you ask anyone who 0 television, they will tell you that it was John Logie Baird. While Baird was, of course, extremely important in the history of television, it would be more 1 to see his role as part of a chain of events which finally led to television as we know it today.
The history of television really begins in 1817 with the 2 by Berzelius, a Swedish chemist, of the chemical selenium. It was found that the amount of electric current that selenium could carry 3 on how much light struck it.
This discovery directly led to G. R. Carey, an American inventor, 4 up with the first real television system in 1875. His system used selenium to transmit a picture along wires to a 5 of light bulbs. This picture was not very clear, however.
Over the next few years, a number of scientists and inventors simplified and 6 on Carey's system. It was not 7 1923 that Baird made the first practical transmission. Once again, the picture was sent through wires, but it was much clearer than Carey's had been almost fifty years before.
The Second World War delayed the development of television. After the war, television sets began to flood the market, with the first mass TV 8 watching the baseball World Series in the USA in 1947. Within a few years, television had captured the attention of the whole world.
