RCA was then free, after showcasing electronic television at New York World's Fair on April 20, 1939, to sell electronic television cameras to the public. [7] [30]: 250–254 Farnsworth Television and Radio Corporation was purchased by International Telephone and Telegraph (ITT) in 1951. During his time at ITT, Farnsworth worked in a basement ...
[11] [12] By September 3, 1928, Farnsworth had developed the system sufficiently to hold a demonstration for the press, [12] the first such successful demonstration of a fully electronic television system. [12] In 1929 Farnsworth eliminated a motor generator from the system, so it then had no mechanical parts. Further developments that year ...
August 25 - On August 25, the inventor Philo Farnsworth gave the world's first public demonstration of an all-electronic television system, using a live camera, at the Franklin Institute of Philadelphia. His demonstrations continued for ten days afterwards. Farnsworth's system included his version of an image dissector. [1] [2]

Philo Taylor Farnsworth, the American inventor of all-electronic television in September 1927, contributed [citation needed] to this in an important way. Farnsworth refined a version of his picture tube (CRT) and called it an "Iatron;" generically known as a storage tube. It could store an image for milliseconds to minutes and even hours.
Farnsworth's high school chemistry teacher, Justin Tolman, produced a 1922 sketch as evidence that Farnsworth had been working on the principle of the image dissector and the development of an electronic television system since the early 1920s. Farnsworth won the suit; RCA appealed the decision in 1936 and lost. [1]
At the time Zworykin was attempting to develop an all-electronic television system at Westinghouse, but with little success. Zworykin had visited the laboratory of the inventor Philo T. Farnsworth, who had developed an Image Dissector, part of a system that could enable a working television. Zworykin was sufficiently impressed with Farnsworth's ...
Multipactor was identified and studied in 1934 by Philo Farnsworth, the inventor of electronic television, who attempted to take advantage of it as an amplifier. More commonly nowadays, it has become an obstacle to be avoided for normal operation of particle accelerators , vacuum electronics , radars , satellite communication devices, and so forth.
