In 1898 H.G. Wells wrote a book called War of the Worlds. The book was a fictional story about a Martian invasion of earth. In 1937, on the eve of Halloween, the book was turned into a radio drama. Many people did not hear the introduction of the show saying it was not real. As the show continued the actors made the fictional story sound real. People became upset and fearful. They thought that Martians had really invaded the earth. The next day people learned that no aliens had come to earth.
