On the night of October 30, 1938, radios around America were interrupted with a news flash stating that aliens had landed and were invading Earth. So realistic was the portrayal by Orson Welles and others that there was mass hysteria and panic in many major US cities.    The radio event was adapted from the original book written in 1897 by H.G. Wells and gave us our first space enemy. Lord knows, we have had a bunch since!!!!!!!!
