History of TV

Welcome! 

We are going to learn together about History of the Media here!

Let's enjoy!

At this time,

we will know about 'TV' which everyone love.

The birth of TV

―The method of mechanical scanning of images was pioneeredby the facsimile transmission systems for still imagesー

Alexander Bain introduced the facsimile machene between 1843 and 1846. In 1851, Frederic Bakewell demonstrated a working laboratory version. Paull Julius Gottlieb Nipkow, a 23-year-old German univercity student, proprosed and patented the 'Nipkow disk' in 1884. Nipkow disk was a spinnig disk which has aspiral pettern of holes. Each hole scanned a line of the image. He never created working model of the system, but variations of the disk, "image rasterizer" became exceedingly commom. At the International World Fair, in paris on 25th August 1900, Constantin Perskyi used the word "television" in a speech for the first time in the world. He mentioned about existing electromechanical technologies, the work of Nipkow and others as well. In 1907, Lee de Forest and Arthur Korn made the design practical. Georges Rignoux and A. Fournier carried out the first demonstration of the live transmission of images. By the 1920s, when amplification made television practical, Scottish inventor John Logie Baird employed the Nipkow disk in his prototype video system. He demonstrated the transmition of the image of a moving face by radio by 26 January 1926. This is widely regarded as the first television demonstration. the face of His business partner, Oliver Hutcshinson was used. In 1928, Baird's company (Baird Television Development Company/Cinema Television) broadcast the first transatlantic television signal, between London and New York, and the first shore-to-ship transmission. In the same year, WRGB, then W2XB was started as the world's first television station. It broadcast from the General Electric Facility in Schenectady, in New York .It was popularily known as WGY Television. Philo Taylor Farnsworth, an American 21-year-old inventor, demonstrated "electronic television" which scanned images with a beam of electrons and is the direct ancestor of modern televison, in San Fransisco on Septenber 7, 1927. Farnsworth had begun to concieve of a system that could capture moving images in a form that could be coded onto radio waves and then transformed back into a capture on a screen. In 1941 the first commercial television starts broadcasting in the US.

Wow, enormous inventors were concerned with invention of TV!

There were much more people in the history of TV!
