On a warm Halloween Eve, October 30, 1938, during a broadcast of H. G. Wells’ War of the Worlds, a twenty-three-year-old Orson Welles held his hands up for radio silence in the CBS studio in New York City while millions of people ran out into the night screaming, grabbed shotguns, drove off in cars, and hid in basements, attics, or anywhere they could find to get away from Martians intent on exterminating the human race. As Welles held up his hands to his fellow actors, musicians, and sound technicians, he turned six seconds of radio silence—dead air—into absolute horror, changing the way the world would view media forever, and making himself one of the most famous men in America. Join us to hear the story of how one broadcast changed broadcasting history forever.
