Television
Jenkins moved on to work on television. He published an article on "Motion Pictures by Wireless" in 1913, but it was not until 1923 that he transmitted moving silhouette images for witnesses, and it was June 13, 1925 that he publicly demonstrated synchronized transmission of pictures and sound. He was granted the U.S. patent No. 1,544,156 (Transmitting Pictures over Wireless) on June 30, 1925 (filed on March 13, 1922).
His mechanical technologies (also pioneered by John Logie Baird) were later overtaken by electronic television such as devised by Vladimir Zworykin and Philo Farnsworth.
In 1928, the Jenkins Television Corporation opened the first television broadcasting station in the U.S., named W3XK, which went on air on July 2 and first sent from the Jenkins Labs in Washington and from 1929 on from Wheaton, Maryland on five nights a week. At first, the station could only send silhouette images due to its narrow bandwidth, but that was soon rectified and real black-and-white images were transmitted.
In March 1932, Jenkins Television Corporation was liquidated, and its assets were acquired by Lee DeForest Radio Corporation. Within months, the DeForest company went bankrupt, and the assets were bought by RCA, which stopped all work on electromechanical television.

Famous quotes containing the word television:
“In full view of his television audience, he preached a new religion—or a new form of Christianity—based on faith in financial miracles and in a Heaven here on earth with a water slide and luxury hotels. It was a religion of celebrity and showmanship and fun, which made a mockery of all puritanical standards and all canons of good taste. Its standard was excess, and its doctrines were tolerance and freedom from accountability.”
—New Yorker (April 23, 1990)
“All television ever did was shrink the demand for ordinary movies. The demand for extraordinary movies increased. If any one thing is wrong with the movie industry today, it is the unrelenting effort to astonish.”
—Clive James (b. 1939)
“The television screen, so unlike the movie screen, sharply reduced human beings, revealed them as small, trivial, flat, in two banal dimensions, drained of color. Wasn’t there something reassuring about it!—that human beings were in fact merely images of a kind registered in one another’s eyes and brains, phenomena composed of microscopic flickering dots like atoms. They were atoms—nothing more. A quick switch of the dial and they disappeared and who could lament the loss?”
—Joyce Carol Oates (b. 1938)
