On 30 October of 1938, Welles directed the Mercury Theatre On the Air in a dramatization of The War of the Worlds, based on H.G. Wells' novel. Setting the events in then-contemporary locations (The "landing spot" for the Martian invasion, Grover's Mill, New Jersey, was chosen at random with a New Jersey road map) and dramatizing it in the style of a musical program interrupted by news bulletins, complete with eye-witness accounts, it caused a nationwide panic, with many listeners fully convinced that the Earth was being invaded by Mars. The next day, Welles publicly apologized. While many lawsuits were filed against both Welles and the CBS radio network, all were dismissed. The incident is mentioned in textbook accounts of mass hysteria and the delusions of crowds.
