• April 30 – Franklin D. Roosevelt, appearing at the opening ceremony of the 1939 New York World's Fair, becomes the first President of the United States to give a speech that is broadcast by television.

• September 1 – The anticipated outbreak of World War II brings television broadcasting at the BBC in Britain to an end at 12:35 p.m. after the broadcast of a Mickey Mouse cartoon, Mickey's Gala Premier, various sound and vision test signals, and announcements by presenter Fay Cavendish. It is feared that the VHF waves of television would act as a homing signal for guiding enemy bombers to central London: in any case, the engineers of the television service would be needed for the war effort, particularly for development of radar. The BBC would resume its broadcasting, with the same Mickey Mouse cartoon, after the war in 1946.^[1]
