| 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 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 film 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 called 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 executives, transmitting the still image of an "X". The picture is said to be dim, with low contrast and poor definition. | |
| October | 02 | John Baird achieves the first live television image with tone graduations (not silhouette or duotone images) in his laboratory. Baird drags office boy William Taynton in front of the camera to become the first face on television. But rate of five images per second is below realistic movement. |

Famous quotes containing the words global, television and/or events:
“However global I strove to become in my thinking over the past twenty years, my sons kept me rooted to an utterly pedestrian view, intimately involved with the most inspiring and fractious passages in human development. However unconsciously by now, motherhood informs every thought I have, influencing everything I do. More than any other part of my life, being a mother taught me what it means to be human.”
—Mary Kay Blakely (20th century)
“It is not heroin or cocaine that makes one an addict, it is the need to escape from a harsh reality. There are more television addicts, more baseball and football addicts, more movie addicts, and certainly more alcohol addicts in this country than there are narcotics addicts.”
—Shirley Chisholm (b. 1924)
“As I look at the human story I see two stories. They run parallel and never meet. One is of people who live, as they can or must, the events that arrive; the other is of people who live, as they intend, the events they create.”
—Margaret Anderson (1886–1973)
