The invention of television is the result of long-term efforts of several men. However, two important people whose names are associated with the invention of television are Vladimir Zworykin, and Philo Farnsworth. Although prior to 1922 the concept of television was very much in existence, it was primarily due to the efforts of these two people that the concept of electronic scanning of images, which forms the bases of modern day television, was introduced. Both Zworykin and Farnsworth had applied for a patent of the same during the year 1923 and 1927 respectively. But as Zworykin has filed the patent earlier, he is often termed as the â€œthe father of televisionâ€. However, the work of Farnsworth cannot be underestimated. In fact many believe that at least six of his basic patents are being utilized in the manufacture of modern day television.
The history of television can be divided into â€œMechanical Televisionâ€ era, which primarily comprises a period prior to 1935, and the â€œElectronic Televisionâ€ era, which is the post 1935 period. Prior to 1935, televisions were not entirely electronic. In the year 1926 the first demonstration of the mechanical television as given by John Baird revealed that the images displayed on the television lacked outlines, were blurred and were also quite small in size. It was only in the post 1935 period that electronic televisions emerged and various countries began broadcasting television programmes.
