"If it weren't for Philo T. Farnsworth. inventor of television, we'd still be eating frozen radio dinners." -Johnny CarsonGerman, Paul Nipkow developed a rotating-disc technology to transmit pictures over wire in 1884 called the Nipkow disk. Paul Nipkow was the first person to discover television's scanning principle, in which the light intensities of small portions of an image are successively analyzed and transmitted.
In the 1920's, John Logie Baird patented the idea of using arrays of transparent rods to transmit images for television. Baird's 30 line images were the first demonstrations of television by reflected light rather than back-lit silhouettes. John Logie Baird based his technology on Paul Nipkow's scanning disc idea and later developments in electronics.
Charles Jenkins invented a mechanical television system called radiovision and claimed to have transmitted the earliest moving silhouette images on June 14, 1923.
Electronic television is based on the development of the cathode ray tube, which is the picture tube found in modern TV sets. German scientist, Karl Braun invented the cathode ray tube.
"Television was not invented by a lone genius in a moment of inspiration. It evolved over decades through the contributions of many." -Canada Science and Technology Museum

Some historians have gone so far as to suggest that Farnsworth and Zworykin should be regarded as "co-inventors." But that conclusion ignores Zworykin's 1930 visit to Farnsworth's lab, where many witnesses heard Zworykin say "I wish that I might have invented it." Moreover, it ignores the conclusion of the patent office, in its 1935 decision in Interference #64,027, which states quite clearly "priority of invention awarded to Farnsworth."
The real inventor of the color television was (1917-1965), a Mexican national from Guadalajara Jalisco. His project was rejected by the Mexican authorities and had to go to the United States. In 1934 he made his first TV when he was 17 years old, later he patented his color TV in Mexico and the US. From there the invention went to different parts of the world.
