March 25 John Logie Baird held the first public demonstration of his "televisor" at the Selfridges department store on London's Oxford Street. The demonstrations continued through April of that year. The system consisted of 30 lines and 12.5 pictures per second.
June 13 - Charles Francis Jenkins achieves the first synchronized transmission of a moving silhouette (shadowgraphs) and sound, using 48 lines, and a mechanical system. A 10-minute film of a miniature windmill in motion is sent across 5 miles from Anacostia to Washington, DC. The images were viewed by representatives of the National Bureau of Standards, the United States Navy, the Department of Commerce, and others. Jenkins called this "the first public demonstration of radiovision"
October - Baird achieves the first recognisable television image (more than a mere silhouette) in his laboratory. Baird drags office boy, William Taynton, in front of the camera to become the first face on television.
