Mechanical television (also called televisor) was a broadcast television system that used mechanical or electromechanical devices to capture and display video images. However, the images themselves were usually transmitted electronically and via radio waves. The reason for the dual nature of mechanical television lay in the history of technology.
The earliest mechanical television components originated with 19th-century inventors, with 20th-century inventors later adding electronic components as they were created. Mechanical systems were used in television broadcasting from 1925 to 1939, overlapping the all-electronic television era by three years.

Famous quotes containing the words mechanical and/or television:
“A man should have a farm or a mechanical craft for his culture. We must have a basis for our higher accomplishments, our delicate entertainments of poetry and philosophy, in the work of our hands.”
—Ralph Waldo Emerson (1803–1882)
“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)
