George Carey was the person whose name is documented to send components of pictures over a series of multiple circuits. However, W. E Sawyer, suggested the possibility of sending an image over a single wire by rapidly scanning parts of the picture in succession.

On December 2, 1992 Edwin Belin, an Englishman, deomonstrated a mechanical scanning device that was the first version of modern television.

He had held the patent for the transmission of photographs by wire, Fiber Optics and also through radar. Belin's mechanical scanning device captured flashes of light and sent them at a selenium element connected to an electronic device that produced sound waves. Then the sound waves were received at another location which were remodulated back into flashes of light on a mirror.

So far at this point, the concept of television was established but still electronic scanning of images yet to be invented. In this race, two names have been conflicting over the real inventor of modern television.

Vladimir Kosma Zworykin, a Russian Born American Inventor and Philo Taylor Farnsworth, a farm boy from the state of Utah. Both worked on same issue over same time period. Zworykin had a patent but Farnsworth had a picture.
