Television as a means of transmitting information. The Role of Television in the Life of Modern People There are several factors that indicate the role of television and the presence of blue screen addiction.

What do children see on the screen? In 116 hours, 486 scenes of violence (murder, fighting, etc.) and erotica were shown. There are 4 scenes of violence and eroticism in one hour. Every 15 minutes an act of aggression, violence or an erotic scene. On average, a Russian teenager sees at least nine "live pictures" every day

Children perceive violence as a possible way to resolve conflicts. The person becomes more vulnerable to violence in real life. More likely to become a victim of violence There is a significantly higher chance that a child will grow up to be an aggressive person and may even commit a crime.

Learning learning difficulties and reduced attention (low school performance) risk of failing the entrance exams to higher school maladjustment to real life: they communicate less and worse with peers, weaned to think for themselves. Expression of speech deteriorates Lack of mathematical and reading skills Television does not contribute to school performance, but, as a rule, affects it negatively.

Television is a source of information as well as a medium for entertainment and education. Not so long ago, it was customary to watch TV shows with the whole family. At the end of the session, disputes and reflections arose regarding this or that moment. Today role of television neither a person has changed significantly, and films, programs or cartoons are of a different nature, which does not always have a positive effect on people. Very often people become addicted to television.

There are several factors that indicate the role of television and the presence
depending on the blue screen:

• spending time in front of the TV for more than four hours
  day;
• irritability and nervousness because there is no way
  watch a TV show or movie;
• all hobbies, communication with friends and other joys of life
  are relegated to the background in favor of the film;
• there is a desire to buy only those goods that are often
  advertised on TV;
• actions in real life repeat the actions of loved ones
  movie heroes;
• all information shown on TV is perceived as
  true.

Influence of TV especially strong, so it is necessary to limit the baby's stay in front of the screen. It is better to purchase modern TV models, since the most dangerous radiation emanates from the back panel of outdated samples. Toshiba LCD TVs were among the first to hit the market and are the best choice today.

As for the influence of TV on the psyche, everything is much more complicated here. Scientists have conducted more than one study, according to their results, it became known that children perceive the information shown on TV as reality. That is, they do not understand the difference between fiction and truth.

TV in modern life most often plays a background role, this is taken for granted. A powerful emotional and informative stream often leads to problems that are associated with advertising addiction. People themselves without realizing it become hostages of imposed stereotypes of thinking and behavior. To prevent such negative consequences of TV exposure on a child as poor sleep, excessive excitability, addiction, headaches, decreased vision, it is possible only by reducing the time of watching cartoons and programs to a minimum.

1.Introduction As a bright and unsurpassed phenomenon of the cultural and spiritual life of modern society, television brings to mankind the great benefits of freedom, enlightenment, the possibility of exchanging information, opinions, and brings nations together. Thanks to earthly and unearthly - in the literal sense of the word - capabilities, television delivers information to the house from the other end of the world, from close and distant neighbors. A new era of communication between people is being born. Much has been written and said about the benefits of television. But a serious researcher of this phenomenon is obliged to discern in its future development the social dangers, the underestimation of which can cause, and is already causing noticeable harm to social progress.

The first patent for the electronic television used now was obtained by Boris Rosing, a professor at the St. Petersburg Institute of Technology, who applied for a patent for the "Method of electrical transmission of images" on July 25, 1907. However, he managed to achieve only the transmission of a fixed image at a distance - in the experiment on May 9, 1911. For the first time in history, a moving image was transmitted over a distance on July 26, 1928 in Tashkent by inventors Boris Grabovsky and I.F.Beliansky. Although the act of the Tashkent Tram Trust, on the basis of which the experiments were carried out, testifies that the images obtained were crude and unclear, it is the Tashkent experience that can be considered the birth of modern television.

The first television receiver in history, on which the Tashkent experiment was carried out, was called a "telephot". At the insistence of Professor Rosing, the application for patenting the telephoto was filed by B. Grabovsky, N. Piskunov and V. Popov on November 9, 1925. According to V. Makoveev's memoirs, on behalf of the USSR Ministry of Communications, all the surviving documents on telephony were studied for establishing the possible priority of Soviet science by the television departments of the Moscow and Leningrad Telecommunications Institutes. The final document stated that the operability of the "radiotelephone" was not proven either by documents or by the testimony of direct witnesses. A different opinion regarding the prospects of Grabowski's invention was held in the United States, and in Mitchell Wilson's novel "My brother, my enemy", which sets out the American version of the history of the creation of television, it is the telephoto that is described as the forerunner of modern television.

There were other models of electronic television: the "dissector" by Philo Farnsworth and the "running beam" by Manfred von Ardenne, also invented in 1931, but they could not withstand the competition with the iconoscope. Regular television broadcasting in Russia began on March 10, 1939. On this day, the Moscow television center on Shabolovka, through transmitters installed on the Shukhov tower, broadcast a documentary about the opening of the 18th Congress of the All-Union Communist Party of Bolsheviks. Subsequently, the programs were broadcast 4 times a week for 2 hours. In the spring of 1939, more than 100 TK-1 TVs received programs in Moscow. In the second half of the 20th century, television became widespread. Its role in the world was emphasized by the UN, having established a memorable day - World Television Day.

3. Television (Greek τήλε - far away and Latin video - I see) is a communication system for broadcasting and receiving a moving image and sound at a distance. Television is based on the principle of sequential transmission of frame elements using a sweep. The frame rate is selected mainly on the basis of the smoothness of motion transmission. To narrow the transmission frequency band, interlaced scanning is used, it allows you to double the frame rate (and therefore, to increase the smoothness of the transfer of moving objects).

Spending too much time in front of the TV is unsafe to health. And the harm does not lie only in the danger of losing sight. So, recently, experts published a report on the dangers of excessive TV viewing. This report showed that prolonged television viewing affects mortality from obesity, high blood pressure, diabetes and high cholesterol.

The fact is that when a person pays too much attention to watching TV, he forgets about playing sports or some useful physical activity. People are so attached to the "box" that they even eat near it, not wanting to miss a minute of television broadcasting. But all this (a sedentary lifestyle) negatively affects human health, and in the future can lead to premature death. In their report, the researchers showed how television affects human intelligence. Let's So this report provided statistics for some countries where people are tele-dependent.

Today television has come to every home. The four-hour TV viewing norms per day, recommended by the Ministry of Health, are not followed by anyone. The TV stays on almost all day long. The ability to watch all kinds of TV shows from almost all over the world "chains" a person to the screen for the whole day. Television has an informational and emotional impact on a person. The effect on the nervous system is predominantly unfavorable. Caused by this phenomenon can be the following causes of emotion.

First of all: 1. Do not be closer than 2-3 meters from the screen. 2. It is very harmful to watch TV in the dark. Be sure to turn on some dim light - sconce or floor lamp, positioning the lamp in such a way that the light bulb does not reflect on the screen. 3. It is important to monitor your posture. To indulge in watching your favorite movie while lying on the couch is much less useful than sitting evenly and without hunching on a chair. It also does not hurt to periodically change your location relative to the TV. The main thing is not to sit at too sharp an angle to the surface of the screen. 4. But the most unacceptable is to watch a movie or program while eating. Being distracted by what is happening on the screen, experiencing various emotions caused by what you saw, you deprive yourself of proper digestion and become on the straight path to stomach ulcers.

5. You should sit straight without tilting your head to the left or to the right, the human brain can at a certain moment concentrate only on performing one task. Trying to concentrate on doing your homework and watching TV is one of the worst mental stressors and can strain your eyes. Good vision requires air: the eyes must receive oxygen. Therefore, take care of ventilation. 6. It is especially necessary to control how much time your children spend watching TV. Doctors came to the conclusion that the duration of TV viewing for children under 7 years old should not exceed 30-40 minutes, from 8 to 12 years old - 1 hour, from 12 to 14 years old - one and a half, and from 14 to 17 years old - two hours a day ... If you follow these guidelines, your TV will never harm your health.!

6. Conclusion: After completing this project, I came to the conclusion that TV is a means of transmitting information and plays a big role in people's lives. I studied the history of television, revealed its positive and negative sides and impact on human health. From the "ugly duckling" television has grown into a huge industry, has become the embodiment of the labors and efforts of gifted people who decided to make the dreams of science fiction writers come true. In less than a century, the information web of hundreds of television channels broadcasting in different parts of the world has covered the entire Earth and made almost any information available. It was television that embodied technological progress and the development of mankind, in which we see a reflection of our lives. We often scold television, but in almost every apartment there is a device in a place of honor, which has become an integral part of our life.
