90 years of first signal broadcast on television

International. Since the winter of 1922 there are documentary records of the experiments being carried out by the Scottish inventor John Logie Baird, who using the disc invented by the German Paul Nipkow and a new type of photoelectric cell and a focusing system, developed by himself, achieved the unthinkable, the transmission of images.

The National Television Authority, ANTV, recalled that the first experiments had no major impact, so it decided to move from the coastal city of Hastings to London. The story is curious because what began as a commercial attraction for the Selfridge's warehouse in the London capital and that reached wide popularity, ended in a small private demonstration, which sponsored by the entrepreneur Oliver Hutchinson, took place on January 26,  1926 in the house of the same scientist. Two days later, he occupied a chronicle space in the edition of the Times entitled 'Television'.

In 1927, he founded the Baird Television Development Company and secured sufficient financial support to carry out the first television broadcast from London to Glasgow in May of that year. In 1928 the feat would cross the Atlantic Ocean and transmit images from London to New York.

Fun facts
According to an ABC science publication, to sponsor his television experiments, the Scotsman used another invention: chemically waterproof socks, useful for soldiers of World War I in 1917.

'Stooky Bill' is the name of the puppet that Baird used in his demonstrations.

During World War II, Baird's work concentrated on the development of color television. On August 16, 1942, he made the first public demonstration of an electronic tube of tonalities.

Baird's initial system consisted of only 30 vertical lines, with a repetition of 12.5 frames per second and an aspect ratio of 3:7.

Baird is considered one of the most outstanding Scottish scientists in history, along with Alexander Fleming, and physicist James Clerk Maxwell.
