An electron beam scans this image, with the signal being amplified and sent to a transmitter. These impulses are broadcast as radio waves. 7:12 The Kinescope reverses this process at the receiving end, using synchronized electron beams to reconstruct the picture on a screen. 7:39 In 1931, NBC (an RCA service) set up an experimental tv antenna on the Empire State Building. 8:24 By 1937, television expanded with RCA and NBC's mobile vans, connecting the world via microwaves. 9:04 Television made its public debut at the 1939 New York World's Fair. 9:39 NBC televised President Franklin D.
