fultograph
The fultograph was an early, clockwork image-receiving device, similar in function to fax machines. It took signals from the loudspeaker socket of a radio receiver and used an electrochemical process to darken areas of sensitised paper wrapped on a rotating drum. Invented by Otho Fulton, the system was used briefly in the late 1920s to broadcast images to homes by radio. The machines themselves were expensive (£22 15''s'' 0''d'' in 1928) and required a good receiver to operate.〔(The fultograph, Transdiffusion.org ), retrieved on: August 13, 2007〕
The BBC broadcast Fultograph images in 759 programmes between 1929 and 1932.[BBC Genome ), retrieved on: November 09, 2014〕 The Fultograph was the subject of an article in the British ''RadCom'' amateur radio magazine in October 2007. ]
