Did you know: Today is World Television Day

(Baonghean.vn) - Today is World Television Day, let's go back in time, back to the late 19th and early 20th centuries to learn about stories surrounding the history of mankind's first television.

1. What is television?

Television is a technology in the field of telecommunications electronics, it includes a set of electronic devices. It has the ability to receive radio wave signals as well as transmit electrical signals carrying coded images and sounds, broadcast in the form of radio waves or through fiber optic systems, or coaxial cables.

Television meets both the functions of listening and watching at the same time, the images will be shown on the screens and the sound will be played on the speaker system. Television has the English name Television, in addition there are other names such as TV, Television or more briefly the word television.

2. Who invented television?

The world still knows John Logie Baird as the inventor of the first TV in 1925. However, the origin of TV is more distant and complicated than that. History shows that a German student Paul Gottlieb Nipkow was the first to invent the first electromechanical TV system in 1885.

Nipkow's phonograph design was supposed to convert images into dots. But it wasn't until 1907 that the invention of the magnifying tube technology made the design a reality. At that time, Constantin Perskyi proposed the word TV in a paper presented at the International Electron Institute at the World's Fair in Paris on August 25, 1900.

Philo Farnsworth, an American (born in 1906) invented the first TV in 1927. However, his invention was not recognized by the Radio Association of America (RCA) and it took a long time to argue before the TV copyright was recognized.

In 1924, British scientist Bellde successfully experimented with transmitting and receiving images, allowing images to be transmitted over long distances, pioneering the use of satellite televisions later on.

In 1926, in London, he publicly demonstrated this experiment, which amazed the whole world. Although the TV he researched and created only had two colors: black and white and the image was very blurry, it opened the way for the appearance of later TVs. And Bellde was honored as the "father of TVs".

3. The first color TV

The world's first color TV was invented by John Logie Baird in 1925. John Logie Baird was a Scottish inventor. He was the first person to introduce color television technology using electronic tubes, marking a very important milestone in the history of television technology development.

Logie Baird's demonstration of the first color TV took place in 1928. This TV could run 30 frames in 5 seconds, which was later improved to 12.5 frames/second and John Logie Baird became the most influential person in the TV and television industry at the present time.

4. First TV show

In 1926, the first television program was broadcast by John Logie Baird. It was a puppet show performed by John Logie Baird himself from a series of cameras and fed to a nearby TV screen.

In 1928, Baird broadcast his first overseas television program from London to New York. This is considered the world's first color television broadcast.

5. When was the first commercial TV born?

The World's First Commercial TV Model.

The first commercial TV was introduced in the US in 1938 under the name Dumont Model 180. The TV with an 8x10 inch screen size was sold for $395 at that time, equivalent to nearly $7,000 today.

6. When was the remote control invented?

Nowadays, it is a given that a TV must have a remote control. However, it was not until nearly 30 years after the first TV was invented that the TV remote control was invented. In 1955, Eugene Polley and his colleague, Robert Adler, invented the TV remote control.

When it was first introduced, the device was called “Flash-Matic” and used photoelectric effect to interact with TV. It gradually replaced the cable control devices that were popular at that time. In 1997, Polley and Adler’s remote control invention was awarded an Emmy Award by the American Television Academy.

7. The first professional television program

On November 2, 1936, from Alexandra Palace Victoria in North London, the BBC broadcast its first professional television broadcast, marking the beginning of world television. According to the remaining data, at that time, only about 500 TV sets received the program's signal.

At that time, the BBC used two systems to transmit signals, Baird 240 lines and Marconi-EMI 405 lines. However, after 6 weeks of alternating test broadcasts, the Baird system revealed its shortcomings. It was too cumbersome and the effects were inferior to Marconi-EMI. Therefore, Baird was abandoned in early 1937.

In November 1937, the BBC made its first notable outdoor broadcast. It was the coronation of King George VI in Hyde Park, London. The BBC used a portable transmitter mounted on a special vehicle. Thousands of viewers witnessed the broadcast.

8. How many TVs have been sold in the world?

Until now, it is impossible to count how many TVs have been sold in the world. However, according to statistics, in 2013, 79% of households in the world owned at least 1 TV.

9. People's attitudes when watching the first TV

When it was first introduced, the TV was a magical world for viewers at that time. The first time when color TV was introduced at the World Fair held in 1964 in New York City (USA).

To let customers experience the interesting and superior points of color TV compared to black and white TV, the owner of the color TV booth invited customers to record and broadcast live "in action". And people recorded the emotional moments of the first people to watch color TV, from surprise, excitement to shock, panic and booing.

The reactions of the customers were very interesting on camera, the stall owner then recorded these precious moments, at that time, color TV was still a very new and amazing invention to everyone.
