who invented the television and when was it invented
1927 Philo Taylor Farnsworth
title: History of television text: History of television The invention of the television was the work of many individuals in the late 19th century and early 20th century. Individuals and corporations competed in various parts of the world to deliver a device that superseded previous technology. Many were compelled to capitalize on the invention and make profit, while some wanted to change the world through visual and audio communication technology. Facsimile transmission systems pioneered methods of mechanically scanning graphics in the early 19th century. The Scottish inventor Alexander Bain introduced the facsimile machine between 1843 and 1846. The English physicist Frederick Bakewell demonstrated a working title: History of television text: in the development of TV technology in the 19th or 20th centuries.

On 25 December 1926, at Hamamatsu Industrial High School in Japan, Japanese inventor Kenjiro Takayanagi demonstrated a TV system with a 40-line resolution that employed a CRT display. This was the first working example of a fully electronic television receiver. Takayanagi did not apply for a patent. On 7 September 1927, American inventor Philo Farnsworth's image dissector camera tube transmitted its first image, a simple straight line, at his laboratory at 202 Green Street in San Francisco. By 3 September 1928, Farnsworth had developed the title: History of television text: or 2160p) and can also play content from a USB device. Mechanical televisions were commercially sold from 1928 to 1934 in the United Kingdom, United States, and Soviet Union. The earliest commercially made televisions sold by Baird called Televisors in the UK in 1928 were radios with the addition of a television device consisting of a neon tube behind a mechanically spinning disk (patented by German engineer Paul Nipkow in 1884) with a spiral of apertures first mass-produced television set, selling about a thousand units. The first commercially made electronic televisions with cathode ray tubes were manufactured by Telefunken in title: History of television text: exceedingly common. Constantin Perskyi had coined the word "television" in a paper read to the International Electricity Congress at the International World Fair in Paris on August 24, 1900. Perskyi's paper reviewed the existing electromechanical technologies, mentioning the work of Nipkow and others. However, it was not until 1907 that developments in amplification tube technology, by Lee de Forest and Arthur Korn among others, made the design practical. The first demonstration of the "instantaneous" transmission of images was by Georges Rignoux and A. Fournier in Paris in 1909.
