This Day In History
On January 27, 1926, John Logie Baird, a Scottish inventor, gives 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.
