Did you know that color television was originally invented around the same time as black and white television?

Color television is possible because the human brain has the ability to transform a series of different colored dots (also known as pixels, short for picture elements) into a colored image. Each of the negative terminal beam tubes of color television has three electron beams. Black and white televisions have only one electron beam in the negative terminal beam tubes. The perforations placed behind the perforations of the masked tubes contain a surface covered with red, green, and blue phosphor dots. All detected colors are formed by a mixture of red, green and blue signals (if all these color signals are active, white will be displayed on a color television).

The reason why the invention of color and black-and-white televisions coincides with almost the same period is that color televisions have a structure that is only three times more complex than black-and-white televisions. John Logie Baird (1888-1946), along with Philo Farnsworth, are known as leaders of television development. In 1928, Baird invented the transfer of color images.

The requirement for the signals used in the transmission of color images to create color images on color televisions but black and white images on black and white televisions was an issue that the team working on this project had to pay attention to commercially. The development of technology was slow and sales of RCA negative pole ray tube televisions began in 1954. The first color televisions were very expensive. Their prices were often more than $1,000. "Walt Disney's Gorgeous Color World," released on a Sunday night in 1961, prompted the purchase of color television by the citizens of the United States. By 1972, the total sales figure of color televisions was more than black and white televisions.

John Logie Baird FRSE (13 August 1888 – 14 June 1946) was a Scottish inventor, electrical engineer, and innovator who demonstrated the world's first live working television system on 26 January 1926. He went on to invent the first publicly demonstrated colour television system and the first viable purely electronic colour television picture tube.

Who is John Logie Baird?

The history of television, one of the indispensable tools of the 21st century, began with the discovery of Scottish inventor John Logie Baird. Baird was the father of television in the 21st century, which could make people sit in front of it for hours. Baird's fascination with exploration began as a child. At the age of 12, Baird had installed an electrical system in his home, and then developed the first telephone exchange that would enable him to talk to his friends while on the road. Baird took electrical courses at the Royal Technical College in Scotland and studied electrical engineering at the University of Glasgow. The inventor, who interrupted his education during the First World War, wanted to work in the armed forces, but was not accepted. Baird's application was rejected and he started working for the Clyde Valley Electric Power Company, but health problems caused him to quit.

Having worked various jobs, including working at a jam factory in Trinidad, Baird finally returned to his hometown of Sussex in 1922, where he started a tinkerer. His humble life in Sussex gave Baird the opportunity to concentrate on the television invention he had dreamed of for 50 years.

Baird, who made his first television set with a sink and a tea can because he had no money, developed a simple setup by covering the projection lamp with a biscuit tin in his next attempt, and adding used lenses and scanning disks from circuits to the setup. This device, invented by Baird, was in the form of a device attached between wooden sticks with embroidery needles and wax. And this setup was accepted as the grandfather of Color TV. Continuing his work after that, the inventor succeeded in realizing the first primitive television image transmission, which he called "Stock ey Bill", as he had imagined in 1925. Logie Baird's invention was brilliant, but not taken very seriously.
