Events[edit]
| Month | Day | Event |
|---|---|---|
| March | 25 | John Logie Baird performed the first public demonstration of his "televisor" at the Selfridges department store on London's Oxford Street. The demonstrations of moving silhouette images continued through April. 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 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". |
| July | 13 | Vladimir Zworykin applies for a patent for color television. |
| c. August–October | 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. | |
| October | 2 | 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. But the rate of five images per second does not show realistic movement. |
