1922–1925

  • 1922: Charles Francis Jenkins' first public demonstration of television principles. A set of static photographic pictures is transmitted from Washington, D.C. to the Navy station NOF in Anacostia by telephone wire, and then wirelessly back to Washington; Philo Farnsworth first describes an image dissector tube, which uses cesium to produce images electronically. Farnsworth will not produce a working model until 1927.
  • 1923: Charles Jenkins first demonstrates "true" television with moving images. This time 48-line moving silhouette images are transmitted at 16 frames per second from Washington to Anacostia Navy station; Vladimir Zworykin applies for a patent for an all-electronic television system, the first ancestor of the electric scanning television camera. The patent is not granted until 1938 after significant revisions and patent interference actions.
  • 1924: John Logie Baird demonstrates a semi-mechanical television system with the transmission of moving silhouette images in England; Vladimir Zworykin files a patent application for the kinescope, a television picture receiver tube.
  • 1925: John Logie Baird performs the first public demonstration of his "televisor" at the Selfridges department store on London's Oxford Street; Charles Francis Jenkins achieves the first synchronized transmission of a moving silhouette (shadowgraphs) and sound, using 48 lines, and a mechanical system; Vladimir Zworykin applies for a patent for color television; Zworykin first demonstrates his electric camera tube and receiver for Westinghouse corporation executives, transmitting the still image of an "X"; John Baird achieves the first live television image with tone graduations (not silhouette or duotone images) in his laboratory. Baird brings office boy William Taynton in front of the camera to become the first face televised.
