In 1926, Hungarian engineer Kálmán Tihanyi designed a television system utilizing fully electronic scanning and display elements, and employing the principle of "charge storage" within the scanning (or "camera") tube. John Ambrose Fleming: Fleming invented the two-electrode radio rectifier; or vacuum diode, which he calls an oscillation valve. Based on Edison's lightbulbs, the valve reliably detects radio waves. Transcontinental telephone service becomes possible with Lee De Forest's 1907 patent of the triode, or three-element vacuum tube, which electronically amplifies signals. Nikola Tesla: Tesla granted a US patent for a system of transmitting electrical energy and one for an electrical transmitter. Guglielmo Marconi: Marconi picked up the first transatlantic radio signal, transmitted 2000 miles from Marconi station in Cornwall, England. James Clerk Maxwell: Maxwell theorized that changes in electrical and magnetic forces are sending waves spreading through space at 186,000 miles per second. Light is made up of such waves, and others might exist at different frequencies. Heinrich Hertz: Heinrich Hertz confirmed Maxwell's surmise with an apparatus that used sparks to produce an oscillating electric current; the current, in turn, generated electromagnetic energy that caused matching sparks to leap across a gap in a receiving loop of wire a few yards away. The Inventers

Before radio & television the public had limited access to long distance information around the world, so they had no way of knowing what happens (news, events, etc.). Tesla, Marconi, Maxwell, and Hertz solved this problem in: 1864, 1888, 1900, and in 1901; by patenting for the inventions, picking up the first transatlantic radio signal, and realizing that that changes in electrical and magnetic forces send waves spreading through space at 186,000 miles per second. Hmmmm…

In the years 1864 and 1900, Tesla and Maxwell used brainstorming to come up with ideas. Tesla came up with a “system of transmitting electrical energy”, and an “electrical transmitter.” Maxwell came up with the theory that changes in electrical and magnetic forces send waves spreading through space at 186,000 miles per second.

Fleming, Maxwell, and Tihanyi did the design step of the design process. Maxwell theorized that changes in electrical and magnetic forces send waves spreading through space at 186,000 miles per second, and Hertz proved him right. Fleming designed the vacuum diode. A vacuum diode is a two-electrode radio rectifier, and it reliably detects radio waves. Tihanyi designed a television system utilizing fully electronic scanning and display elements, and employing the principle of "charge storage" within the scanning (or "camera") tube.

Fleming built, Hertz evaluated, and Marconi tested. Fleming built the vacuum diode or two-electrode radio rectifier. Marconi picked up the first transatlantic radio signal. Hertz evaluated Maxwell’s theory and proved him right by using sparks to produce an oscillating electric current which generated electromagnetic energy that caused matching sparks to leap across a gap in a receiving loop of wire a few yards away.

Truly the first post war American television was marketed in August, 1945 as a 1946 model. The president of Viewtone, Mr. Irving Kane, was the marketer of the television.
