Global Television Events
| Month | Day | Event |
|---|---|---|
| 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)
“Photographs may be more memorable than moving images because they are a neat slice of time, not a flow. Television is a stream of underselected images, each of which cancels its predecessor. Each still photograph is a privileged moment, turned into a slim object that one can keep and look at again.”
—Susan Sontag (b. 1933)
“When the course of events shall have removed you to distant scenes of action where laurels not nurtured with the blood of my country may be gathered, I shall urge sincere prayers for your obtaining every honor and preferment which may gladden the heart of a soldier.”
—Thomas Jefferson (1743–1826)
