Philo Taylor Farnsworth (August 19, 1906 – March 11, 1971) was an American inventor and television pioneer. [2] [3] He made the critical contributions to electronic television that made possible all the video in the world today. [4]
Philo Farnsworth achieves an experimental electronic television image, of a straight line, at his laboratory at 202 Green Street in San Francisco. [4] 20: John Logie Baird demonstrates the first ever system for recording television. His Phonovision VideoDisc apparatus records 30-line television pictures and sound on conventional 78 rpm ...
Philo Farnsworth, credited for inventing the first fully functional all electronic television system (U.S. patent 1,773,980, filed Jan 7, 1927), worked at Philco from 1931 to 1933. [ 4 ] [ 5 ] Early history

This is widely regarded as the first electronic television demonstration. Many inventors had built electromechanical television systems before Farnsworth's seminal contribution, but Farnsworth designed and built the world's first working all-electronic television system, employing electronic scanning in both the pickup and display devices.
