Jun 5th Who Invented Television

Today, all TV is already commonplace. And before people came to each other "on the TV series," even the installation of antennas was the whole ritual. That will place the antenna on a stool, then try to attach the window. In today's world no television anywhere, and in the metropolis, and in the remote village, even the installation of satellite dishes – a usual thing. But who was the man who invented television? The idea of image transmission over long distances is ripe deep in antiquity. To recall a Russian fairy tales with apple and saucer, which showed the overseas countries and cities.

One theoretical and technical basis for translating this into reality has appeared only in the late nineteenth century, after the establishment of the radio. The main principle of operation in 1880, was independently proposed by two scientists. American VE Sawyer and the Frenchman Maurice Leblanom. He was in the rapid scanning of each pixel of order, so is, sequentially, frame by frame. And in 1884, Paul Nipkow disk Nipkov invented, which gave life to mechanical television. Between 1910 and 1920 made many improvements in technology for television. (Similarly see: PCRM). In particular, first Telescope invention or method of amplifying electronic signals.

It is worth noting that in 1908, it was proposed two-color device for signaling, its patented Hovhannes Adamyan. And in 1918, Adamian gathered first in Russia installation, which was able to show black and white, but only static. It was a big step in the development of television. Adamian in 1925, registers a patent for a three-color electromechanical system Television, Power transmission has been demonstrated in zhe1925 in the city of Yerevan. The first-ever television receiver called "telephoto". Zworykin made a breakthrough in technology of electronic television, he gave application, in which television was completely electronic. In 1927 the U.S. began regular broadcasts on a system with optical – mechanical-scan images. And the first regular TV on the UHF band appeared in Germany in 1935. And although the production of television was interrupted by World War II, after it has not lost its appeal. In the U.S. it has become even greater buying power. For example, if in 1947 United States was approximately 180,000 television sets, by 1953 their numbers had risen to 282 million. Saturation of the market in black and white television made U.S. radiopromyshlennikov create a new product. And they are seriously engaged in the creation of color television. It was designed and created a system of NTSC, and in 1953 began regular color television. But the first color TV became available only a decade after this, since the beginning of the cost of one TV was about $ 1,000, and its maintenance cost per year of about the same money. In those days this was half the cost of the car. As we see in the history of television there is no single name of the inventor, the work of many scientists allowed to come to the modern television in every home.
