Produced: At the end of the 19th century, a few pioneers began to research and design technologies for transmitting images. In 1904, the Englishman Bellwell and the German Koron invented the technology of teletransmitting one photo at a time. Each photo transmission takes 10 minutes. In 1924, British and German scientists used mechanical scanning to successfully transmit still images at almost the same time. However, the distance and range of cable mechanical television transmission was very limited, and the images were quite rough.
Growth: In 1923, Russian-American scientist Zvorigin applied for patents for photoelectric picture tubes, TV transmitters and TV receivers. For the first time, he adopted a comprehensive "electronic TV" transmitting and receiving system and became the pioneer of modern TV technology. The application of electronic technology on televisions enabled televisions to come out of the laboratory and into public life. In 1925, British scientists successfully developed televisions.

Maturity: In 1929, American scientist Ives broadcasted 50 lines of color television images between New York and Washington, and invented the color television. In 1933, Zworigin successfully developed a camera tube and a picture tube for television cameras. Completed the process of making TV camera and display completely electronic. So far, the modern TV system has basically taken shape.
