television can be traced back to 1924. According to records, the world's first television was born in a British electronic engineer named John Baird. But people usually regard October 2, 1925 as the symbol of the birth of the television. Because on the same day the electrical engineer "scanned" an image of the puppet in an experiment in London. Therefore, he is also known as the "father of television." But there are always objections to this kind of talk, because there are many people doing the same research at the same time.
In fact, this is not very important. The important thing is that in 1928, Baird’s company began mass production of TV sets, and the TV set named Baird c model became the first in the world to be mass produced. Qualified TV.
Until 26 years later, in 1954, the world's first color television was shown in front of people. It was developed by Texas Instruments Inc., and it was also the world's first all-transistor TV. The price in the United States was as high as $1,000.
until 1972, under the vigorous promotion of Sony Corporation of Japan, changed the method of television program production. Because Sony introduced a 3/4-inch tape. It is because of the birth of this kind of tape that video recording technology has developed rapidly. Video recorders of various models and functions also appeared. Make the picture sound and clarity technology more and more perfect.
According to records, the largest television that ever appeared in history was made in England and named Zeus. It is 9 meters long and weighs 1 ton, and can watch 20 channels at the same time. It is equipped with 65 million pixels and can be changed through gestures.

I have to say that today's TVs are getting stronger, but I don’t know if you have noticed. Only after the rise of mobile phones, TV sets have become less and less people watching. However, most families will be equipped, but fewer and fewer people really watch.
And my country only produced the first black and white TV in 1958. At that time, the Great Leap Forward boom was at the time when Tianjin 712 Factory produced a Beijing brand 14-inch black and white TV. my country’s TV technology at the time was almost on the same starting line as Japan’s, but the development of color TV in my country was a bit more difficult. It took 70, 80, and 90 years of development to slowly stabilize its development!
and things up to now. TV in our country has also spread to every household. The TVs on the market are also changing day by day. From production to sales to users, they have become a complete whole. There are more and more brands for me to choose from, and the functions for us to choose are more and more powerful. Although mobile phones are slowly eroding the TV industry today, no one can say for sure in the future, right? What do you think the future of television will develop into? Will it slowly be eliminated and will gradually evolve into another model? This problem will have time to witness!
