The Iconoscope is one of the first television “cameras” developed by Russian inventor Vladimir Zworykin in the early days of television. This early camera tube was equipped for rapid scanning and information storing of the photoactive mosaic that was to become the television broadcast. Equipped with the iconoscope and a cathode ray tube, Zworykin and RCA officially launched the television industry in 1931.
