1920s edit

  • 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, but 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.

Baird brings office boy William Taynton in front of the camera to become the first face televised.
