TV DEMONSTRATED ON THIS DAY IN 1926

On January 26, 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.

Baird based his television on the work of Paul Nipkow, a
German scientist who patented his ideas for a complete
television system in 1884.
