Baird demonstrates television

In 1926, John Logie Baird, a Scottish inventor, gave the first public demonstration of a true television system in London, launching a revolution in communication and entertainment. Baird's invention, a pictorial transmission machine he called a “televisor,” used mechanical rotating disks to scan moving images into electronic impulses. This information was then transmitted by cable to a screen where it showed up as a low-resolution pattern of light and dark. Baird's first television program showed the heads of two ventriloquist dummies, which he operated in front of the camera apparatus out of view of the audience.
