In 1938, millions of Americans thought Martians had invaded Earth after a radio broadcast sounded so real that it triggered nationwide panic

In 1938, radio drama caused panic across America: Orson Welles' 1938 radio broadcast of The War of the Worlds caused widespread confusion after its realistic news format led some listeners to believe that Martians were invading Earth. While some panic did occur, historical research suggests the scale of the hysteria was likely exaggerated. Welles later apologised for any distress caused, sparking debate over broadcasting ethics. The broadcast remains a landmark in media history and storytelling.
