Nipkow’s spinning disc design is considered to convert images to points. But it wasn’t until 1907 that the invention of magnifying tube technology made drawings a reality. Around this time, Constatin Perskyi proposed television in a publication at the International Institute of Electronics at the Paris International Fair on August 25, 1900.

Philo Farnsworth, an American (born 1906), produced the first television in 1927. However, his patent was not recognized by the American Radio Association (RCA) and has long been controversial. the newly recognized television rights belong to me.

In 1924, British scientist Bellde successfully transmitted and received images, allowing images to travel long distances, pioneering future satellite televisions. .

In 1926, in London, he publicly carried out this experiment which surprised the whole world. Although the TV he worked on only had two colors in black and white and the picture was very blurry, it opened the door for newer TVs to appear. And Bellde is considered the “ancestor of televisions”.

However, after 6 weeks of alternate testing, the Baird system revealed its shortcomings. It was too bulky and the effects were inferior to Marconi-EMI. As a result, Baird was scrapped in early 1937.
