Martians on the Radio: The War of the Worlds Broadcast

At 8 p.m. Eastern time on 30 October 1938 — the night before Halloween — CBS listeners heard dance music from the “Meridian Room” interrupted by increasingly frantic news bulletins: strange explosions on Mars, a cylinder fallen on a farm at Grover’s Mill, New Jersey, a heat-ray, the military overrun. It was the Mercury Theatre on the Air’s adaptation of H. G. Wells’s The War of the Worlds, directed by and starring a 23-year-old Orson Welles. [3]

An experiment in form

The script, by Howard Koch, made one radical choice: it told the first half of the story entirely through the grammar of live radio news — remote correspondents, interrupted programming, dead air. [1] Radio bulletins breaking into entertainment shows were newly familiar; the Munich crisis had had Americans glued to such interruptions only weeks earlier. The broadcast opened with a clear announcement that it was a dramatization, and repeated it mid-show — but a listener tuning in late, perhaps flipping over from NBC’s far more popular Edgar Bergen program, entered a world already ending.

The panic that mostly wasn’t

The next morning’s front pages told of a nation in terror — highways jammed, hysteria, listeners fleeing Martians. Modern scholarship tells a smaller story: ratings surveys taken that night suggest only a small fraction of the radio audience heard the show at all, and documented cases of genuine panic were scattered and brief. [2] Newspapers, then locked in a rivalry with radio for advertising and authority, had every incentive to inflate the new medium’s supposed danger — and the legend of the great Martian panic has been retold as fact ever since.

Consequences, real and mythical

The FCC looked into the broadcast but issued no sanction, and networks quietly agreed to be more careful with fictional news flashes. [3] For Welles, the scandal was a rocket: within a year he had an unprecedented Hollywood contract at RKO, and in 1941 delivered Citizen Kane. [1]

The broadcast’s true lesson

The War of the Worlds endures not as proof that audiences are gullible, but as an early case study in how media panics are manufactured — a fake invasion, reported as a real panic, by an older medium anxious about a newer one. Every subsequent alarm about a new technology deranging the public has replayed the same script. [2]
