The scientific concept underlying modern television was laid down at the end of the 19th century. In 1980, independently of each other, Frenchman Maurice LeBlanc and American William Sawyer proposed the idea of quickly sequentially scanning images.
The invention of the television took several decades and required the efforts of several dozen world famous scientists. As a result, TV could become one of the main achievements of mankind in the 20th century.
The history of the development of television
In 1984, German scientist Poil Gottlieb Nilkov patented his method of mechanical image scanning, which became fundamental for the further development of television technology.
Another step towards the invention of modern television was the development of Boris Lvovich Rosing, a professor at the Petersburg Technological University, who, on May 22, 1911, received an image of a geometric figure on the screen of a picture tube he designed, which was the world's first television broadcast.
The next developer who made a significant contribution to the development of television was the Scottish engineer John Logdi Byrd. In 1925, he managed to convey the first recognizable image of a human face. A year later, in London, he was able to demonstrate the first television system transmitting moving pictures.
In the late 1920s, General Eletric pioneered television production, demonstrating the first workable system. It was developed in its own R&D center under the guidance of Swedish engineer Ernest Aleksanderson.
The beginning of electronic television
In 1932, the American research laboratory RCA was the first in the world to demonstrate a television with a transmitting electron tube. This marked the beginning of electronic television. The presented prototype used an iconoscope in its design, which was patented back in 1923 by the Russian émigré Vladimir Zvorykin.
At the end of 1936, the first electronic television set suitable for practical use was demonstrated in the USA by the RCA laboratory.
First mass-produced TV
Three years later, in 1939, the RCA laboratory demonstrated the first television set intended for widespread sales in the United States. It was presented at the New York World's Fair. This TV was presented in four versions at once - three console and one desktop, which had a five-inch screen and was called RCA TT-5. All models were produced in handcrafted walnut cabinets.
