The BBC began transmitting from Alexandra Palace in 1936. Transmissions were interrupted by the war with the closedown occurring in the middle of a Mickey Mouse cartoon. During the war, the transmitter was used to jam the radio navigation system used by the Luftwaffe (a forerunner of GPS). TV transmissions resumed after the war and continued until 1956, when operations were relocated to Crystal Palace. The transmitter is still used for local analogue television transmission, local commercial radio and DAB broadcasts.
