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 movie of a miniature windmill in motion was sent across 8 kilometers 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 termed this "the first public demonstration of radiovision".
Zworykin first demonstrates his electric camera tube and receiver for Westinghouse corporation executives, transmitting the still image of an "X". The picture is said to be dim, with low contrast and poor definition.
