The War of the Worlds panic that mostly never happened

On October 30, 1938, Orson Welles staged a Martian invasion on CBS radio. The next morning, newspapers across the country reported a nation in panic. The record shows a small audience and scattered fear, and the legend has outlived the evidence.

The first source

On Sunday, October 30, 1938, from 8 to 9 p.m. Eastern time, CBS aired an episode of The Mercury Theatre on the Air, an unsponsored drama series directed and narrated by 23-year-old Orson Welles. Writer Howard Koch adapted H. G. Wells's 1898 novel The War of the Worlds and moved the Martian landing to Grovers Mill, a village in New Jersey. The first two-thirds of the hour imitated news bulletins breaking into dance music. CBS required about 28 changes in phrasing, because naming real institutions could invite legal action.

The program was identified as fiction four times on the network, and Welles added a closing statement of his own. At a press conference the next day he was asked whether he knew the show would frighten people and answered, "Definitely not," according to Wikipedia's account. In later interviews Welles claimed the Mercury had wanted to fool some listeners, but none of his collaborators endorsed that claim, Smithsonian reports. The broadcast is the origin of the drama. The panic story has a separate first source: the newspapers.

How it spread

That night some listeners phoned police, newspapers and radio stations. Trenton's city manager told the Federal Communications Commission his office took about 2,000 calls in roughly two hours, according to the Rockefeller Archive Center.

The broadcast aired on a Sunday evening, when newsrooms were thinly staffed. Media historian W. Joseph Campbell notes that morning papers leaned on wire-service roundups that stressed breadth over depth, so the same anecdotes appeared across the country. On October 31 the New York Times ran the headline "Radio Listeners in Panic, Taking War Drama as Fact." Wikipedia counts at least 12,500 articles within three weeks. Pooley and Socolow cite a similar figure from a PBS documentary over two weeks, and Campbell found most papers dropped the story within a day or two.

Editorials turned the story against radio. The Times ran an editorial titled Terror by Radio, and the trade journal Editor & Publisher questioned radio's fitness to deliver news. Radio had drawn advertising revenue from print during the Depression. The FCC chose not to punish Welles or CBS. On November 8, 1938, Hitler cited the broadcast in a speech in Munich.

In 1940, Princeton's Hadley Cantril published The Invasion from Mars, a study from the Rockefeller-funded Princeton Radio Research Project. It estimated about 6 million listeners, 1.7 million who took the show as news, and 1.2 million who were frightened or disturbed. Pooley and Socolow summarize his count as about 1 million frightened.

What it became

The panic became a standard classroom example of mass media's influence on audiences. Communication textbooks cast Cantril's book as the powerful-effects stage of media research, according to a 2013 paper by Jefferson Pooley and Michael Socolow in the International Journal of Communication. CBS dramatized the night in a 1957 Studio One episode, "The Night America Trembled," and ABC aired the TV film The Night That Panicked America in 1975. In 1988, West Windsor, New Jersey, put up a bronze monument to the fictional landing. For the 75th anniversary in 2013, a PBS program and a Radiolab piece retold the panic, which Pooley and Socolow argued overstated it. For Welles, the broadcast led to Hollywood and Citizen Kane.

What the record shows

The only measurement taken that night points to a small audience. The C. E. Hooper ratings service phoned 5,000 households. About 2 percent named the play or something indicating CBS. None said they were hearing a news broadcast. The show ran against NBC's Chase and Sanborn Hour, one of the most popular programs of the time, and some CBS affiliates, including WEEI in Boston, did not carry it.

Cantril's larger numbers came from an American Institute of Public Opinion survey taken six weeks later, after the newspaper coverage. He conceded that its audience figure was more than double other measures. He also grouped excited, disturbed and frightened listeners together. The detailed interviews were limited to frightened people in New Jersey, and the Rockefeller Archive Center says they had tuned in late. About a third of those interviewed thought the invaders were Martians. Most thought of a foreign attack or a natural disaster.

Specific panic claims did not hold up. Six New York City hospitals surveyed six weeks later had no broadcast-related cases. A reported heart attack in Baltimore was never confirmed, no paper reported a verified suicide, and a listener's $50,000 lawsuit against CBS was dismissed. Campbell argues that the heavy phone traffic shows people checking with trusted sources, which is a rational response.

Some fear was real. Historian A. Brad Schwartz found that of about 2,000 letters sent to Welles and the FCC, roughly 27 percent came from frightened listeners or people who saw others frightened. Panic researcher Robert Bartholomew says hundreds of thousands were frightened but calls evidence of fear-driven action scant and anecdotal. The dispute is about scale. Pooley and Socolow wrote in Slate that the panic was "so tiny as to be practically immeasurable."

How to trace a claim like this

1. Separate the event from the claim about the event. The broadcast is well documented. The panic claim has its own first source: next-day wire stories written overnight.
2. Do not count copies as witnesses. Thousands of articles drew on the same wire anecdotes. That is republication, not corroboration.
3. Check what a number counts and when it was collected. Cantril's 1.2 million grouped excited, disturbed and frightened listeners in a survey six weeks later. The Hooper figure was gathered that night.
4. Look for records that should exist. Hospital logs and court files are checkable, and here they did not support the dramatic cases.
5. Ask who benefited from the story. Newspapers competing with radio had a stake. A motive is a reason to check a report. By itself it does not make the report false. More cases like this are in our guide to jokes, hoaxes and lies that became movements.
