ABSTRACT
Television progress during 1930 can be gauged by increases in the number of patent applications and technical papers, by engineering developments, and by the staged events that kept television in the public eye. Demonstrations of a large theater screen by General Electric and the two-way visual telephone by Bell Labs were top events in America. The English Baird concern mounted the vaudeville stage to bring large-size images to the public view. While the Baird studio, in cooperation with the BBC, commenced a regular broadcast service in London, experimental broadcasts were also put on by others in Berlin and in Boston, Chicago, Jersey City, New York, Schenectady, Washington, and other American cities.
