Who Was The Inventor Of The First Television

Who was the inventor of the first television? Actually, television is such a complex process that there were many small steps made on the road to it ultimate invention. So, who was the inventor of the first television?

The very earliest TV like devices were based on the photoconductive properties of selenium and a mechanical device that use spinning disks and mirrors to capture light on one mirror and transmit it to another mirror. The spinning disks were invented and built by Nipkow. In 1987, May and Smith from England discovered that selenium�s resistance to electricity decreased when exposed to light. They put forth the idea of using electricity to send pictures but never developed a way to do it. So, who was the inventor of the first television?

Paul Nipkow built a disk with holes cut in a spiral pattern that could read an image one dot at a time as it spun. However there are actual physical limitations that make the process of mechanical scanning of images impractical. However his scanning theory and methods was used as the basis for later developments. So, who was the inventor of the first television?

John Baird of Scotland used Nipkow�s disk to transmit pictures to be displayed on selenium-coated screens to recreate the images. Baird demonstrated this technique in 1925 by sending the image of a face with his device. Baird later achieved the first transatlantic broadcast and began broadcasting as the British Broadcasting Company (BBC) in 1929. So, who was the inventor of the first television?

Charles Jenkins invented the movie projector. Jenkins demonstrated a 10-minute broadcast of a movie in 1925 and called it radiovision. In 1929, AT&T broadcast Herbert Hoover over their phone lines and then a vaudeville act over wireless. They had designed and built the first very primitive videophone. General Electric was airing TV using mechanical scanning in 1929 and broadcast dramatic plays and political speeches over the airwaves. So, who was the inventor of the first television?

Mechanical television could not last because it needed such powerful lighting that actors could not stay on screen for more than a few minutes at a time because of the heat the lights generated. Electronic TV was the way to go, and Vladimir Zworykin and Philo Farnsworth were both working on that. So, who was the inventor of the first television?

Both of these men have been credited for inventing the TV, Zworykin invented the video camera and Farnsworth invented a device to create and manipulate an electron beam that could scan pictures, transmit them to a receiver and recreate the image on a second screen. So, who was the inventor of the first television?

Have you figured out who was the inventor of the first television yet? Zworykin got a patent on his device in 1923 and Farnsworth demonstrated his device in 1927 and patented it in 1930. Philo Farnsworth is generally considered the inventor of modern television because he invented and was the first person to broadcast pictures using an electron beam instead of a mechanical device. So, after reading all that, who was the inventor of the first television?
