When was TV introduced to China? Do you know several periods of TV development?

Television originated from 1929. However, it did appear in China about 20 years later. But it was not imported from abroad, but made in China. 1September 2, 958, the first TV set in China was successfully manufactured, and black-and-white TV began to be broadcast, and its related TV industry was also established. The first TV set was born in 1923. 1923, the British engineer John Lodge Baird invented the television. Television is a device that uses electronic technology to transmit moving images and audio signals according to the transient characteristics of human vision and visual psychology, that is, a television receiver. 1923, the British electronic engineer applied for a patent for his device which can generate eight line graphs. Seven years later, he sold his first TV set. 1932, the BBC broadcast the world's first standardized TV program, and Britain opened the TV era for the first time. Baird is therefore called "the father of television".

The transition from the earliest black-and-white silent TV set to the first color TV set was 1954, because the earliest TV set was silent, the TV image was black and white, and the picture was very blurred. 1954, the world's first color TV was born. This TV set was developed by some American scientists in the laboratory. But the cost of a component in this TV set is very high, so owning a color TV set at that time was also a symbol of wealth.

It was not until later that substitutes such as crystals were invented that the price of color TV sets gradually declined. With the decline in the price of TV sets, more and more people can buy color TV sets.

1972, Sony formula cassette appeared in Japan, and modern TV was born. 1972, Sony cassette appeared in Japan. The appearance of cassette tape has brought a gradual development of TV industry to a higher level and brought earth-shaking changes. After decades of development, modern TV sets have become extremely common. There are also many TV brands and types in the world market. The purchase of TV sets has also increased.

1September 2, 958, the first TV set in China was successfully manufactured, and the color TV was piloted in 1973. Before 1958, China's TV broadcasting industry was still blank. Other countries are relatively backward. In order to change this situation, 1957, the state decided to develop TV broadcasting. At 7: 00 pm on May 1958, the pilot broadcast of Beijing TV Station (the predecessor of CCTV) became the birth day of Chinese mainland TV Station, and it was officially broadcast on September 2, 1958. 1988, China successfully launched a synchronous satellite. Two years later, the satellite broadcast the launch of Asia-1. At this moment, China Satellite TV kicked off. Television was developed in China in the 1990s.

Television has changed from ordinary TV to LCD TV and plasma TV. Transmission technology has also developed from wired to satellite. In the first half of 2005, the sales volume of flat-panel color TVs in China reached 725,000 units, a year-on-year increase of 260%. The ownership rate of LCD TV in urban households reached 3.56%, and the ownership rate of plasma TV also reached 2.8 1%. With the introduction of TV series from Hong Kong and Taiwan, Japanese TV series, European and American TV series and cartoons, TV sets began its peak period, and TV sets turned on φ instead of radios and movies, becoming a necessary household appliance.

The development of television has not reached a hundred years, and it has taken decades from prosperity to decline. Due to the arrival of high technology, a color movie can upgrade a black-and-white TV set to a color TV set. Magnifier can change a 9-inch screen into a 12-inch screen ... black-and-white TV sets can be upgraded to color TV sets, from the original picture tubes to transistors, integrated circuit TVs, new liquid crystal displays, laser tv, projectors and so on. With the rise of smart phones, many people either use projectors or televisions as home decorations. With the progress of the times, more and more things emerge and more and more things are put into the recycling bin of the times. This also shows the progress of science and technology and economy in China. Let the broad masses of the people throughout the country live a better life and enjoy more comfortable entertainment time.

The appearance of the original black-and-white TV set opened a new era for the world. The upgrade of black-and-white TV sets to color TV sets added a touch of bright color to the development of TV sets, and the subsequent appearance of cassette tapes gave people more choices, and they could choose their favorite brands and models of TV sets. Finally, the emergence of technology products such as smart phones has gradually cooled the TV market. The progress of the times will bring us to a better world.
