| 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 marvelous indeed to watch on television the rings of Saturn close; and to speculate on what we may yet find at galaxy’s edge. But in the process, we have lost the human element; not to mention the high hope of those quaint days when flight would create “one world.” Instead of one world, we have “star wars,” and a future in which dumb dented human toys will drift mindlessly about the cosmos long after our small planet’s dead.”
—Gore Vidal (b. 1925)
““The ideal reasoner,” he remarked, “would, when he had once been shown a single fact in all its bearings, deduce from it not only all the chain of events which led up to it but also all the results which would follow from it.””
—Sir Arthur Conan Doyle (1859–1930)
