The names of many are associated with the invention of the television. The two people who worked on the same appliance at two totally different places were Vladimir Kosma Zworykin; a Russian who was born in America and worked for Westinghouse Corporation, the other was a farm boy from Utah, Philo Taylor Farnsworth. Zworykin was the one who got his electron scanning tube also known as iconoscope patented first, in the year 1923 and was thus thought of as the inventor of modern television. The quality of his work was very poor and not appreciated.
It was on September 7, 1927 that Fransworth gave a successful demonstration for the transmission of the television signals for which he used his self designed scanning tube and received the patent for the same in the year 1930.
The patent for a similar type of tube was also applied for by Zworykin in 1923 but he was refused the same as the tube was not in a functional state. He could make a functional tube in the year 1934 and got the patent for it in 1938.
Many people acclaim John Logie Baird to be the original inventor of television as he was the one to give the very first live demonstration of the working television which had images that moved and had tone graduation on 26 January in the year 1926.
