Charles Francis Jenkins achieves the first synchronized transmission of pictures 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 are viewed by representatives of the Bureau of Standards, the U.S. Navy, the Department of Commerce and others. Jenkins calls this "the first public demonstration of radiovision".
