Brochure for Baird Television

On January 27, 1926, John Logie Baird, a Scottish inventor gave the first demonstration of television system in London. He called his new equipment "Televisor" that used mechanical rotating disks to scan moving images into electric impulses. In 1928, he made the first overseas broadcast from London to New York over phone lines. Here are some of the brochures used to publicise Baird Television.
