Modern technologies are so firmly entrenched in our everyday life that we can no longer imagine our life without objects that greatly facilitate our work and life. Among them is a TV. Watching TV shows and even just listening to them during household chores has become an integral part of our lives. Therefore, the question is obvious: are there rules and recommendations on how to watch TV properly so that there is no harm to health.
Very often the TV works for a long time. Someone watches TV shows for nothing for hours. Parents of young children, so that children do not bother them, include for them television programs with cartoons. Of course, our television carries not only an entertaining idea, but a lot of educational programs are also broadcast on television.
Brief historical background
The idea of transmitting images from a distance has existed since ancient times. There are images of this in myths and tales, for example, in the tale of a silver platter and a bulk apple. But only at the end of the 19th century did the technical and theoretical basis for creating such a device appear after the creation of the radio.
In 1884, the German inventor Paul Nipkov invented a device. Nipkov’s disk, which formed the basis of mechanical television. I will not bore you with discoveries and inventions in the field of radio engineering. It was a rather lengthy process and you can read about all this on the Internet. An interesting fact is that the first such device was called a radio watchman.
The first telecasts began in the USA in 1927, of course, they were far from perfect, like the televisions themselves. Later, in 1936, regular television broadcasting began in Europe. In the USSR, regular television broadcasting began on March 10, 1939.
In 1953, in the United States, after the development and creation of the NTSC system, color television appeared. At the same time, the first color TVs appeared, which had to be very difficult to set up. Color television became widespread only in 1966, that is, when Japan started production of relatively cheap color TVs.
