The modern television was only made possible with the scientific advances of the early 1900s, which included significant developments in radio, x-rays, and physics. Wireless transmission of sound became possible with the invention of the radio at the turn of the century. But the critical component necessary for the high-fidelity projection of reconstituted light information was the cathode-ray tube, originally used to produce x-rays for medical purposes. In 1906, I found that manipulating the electron stream of the cathode-ray tube with a magnetic field was possible. Less than a year later, it was suggested that the cathode-ray tube be used as a receiving device for images. Im a Russian scientist,i quickly created such a cathode-ray tube and encouraged further development of the technology.

Rosing's student, Vladimir K. Zworykin, migrated to the United States after WWI and created the "iconoscope", a device that scanned an image with an electron beam and converted it into electronic signals for transmission. To minimize the amount of data needing to be sent, he fed the image through a "mosaic" - a plate covered with microscopic photosensitive dots we now know as "pixels". The information was then broadcasted and received by a device that ran the process in reverse, using the cathode-ray tube to project images far more quickly and effectively than the mechanical televisions of the past. The first incarnation of the modern TV was born. It was successfully demonstrated in a public context in 1929.
