War of the worlds broadcast by orson welles (1938) It has a real in uence over them, because it is their only source of international news. Audiences who tuned in late believed the world was actually being attacked by aliens. Invented in 1840, it was an instantaneous mode of communication back in the day. Samuel more developed a way to transmit electrical impulses within wire, hooch let to the discovery of morse code (dots and dashes). First wire was set in between washington dc and baltimore in 1844. In 1866 the rst telegraph line was built transatlantic between newfoundland and. Communication was limited by the reach of the wires though. James maxwell discovered these waves, which allowed wireless communication to ships and other locations through the air. In the mid 1890"s, he developed wireless telegraphy and patented in 1896.
