Panic in the Streets: The War of the Worlds Radio Broadcast

Welles Designed the Broadcast to Mimic Authentic News Reporting For Impact and Engagement

Orson Welles and his writer, Howard Koch, adapt H.G. Wells's 1898 novel The War of the Worlds for radio, transforming it for contemporary impact. While Wells’s original novel is set in England and follows two brothers surviving an alien invasion over several weeks, Welles and Koch set their version in New Jersey and condense the events into a couple of days. This shift localizes the drama for American listeners, amplifying its relevance and immediacy.

Central to Welles’s broadcast is its innovative format: the show is structured as a series of breaking news bulletins that interrupt a regular musical program, closely mimicking how listeners experienced urgent reports about Hitler’s recent expansion into Sudetenland. During CBS’s live broadcast from Hotel Park Plaza, a peaceful Spanish ballad is suddenly interrupted by news bulletins describing strange gas explosions on Mars, purportedly reported by Princeton University scientists. After a brief return to the concert, more interruptions arrive: a meteorite crashes in Grover’s Mill, New Jersey. Reporters describe in tense, realistic detail the emergence of Martians, their violent attacks, and chaotic scenes as people panic and cities fall under poisonous gas.

The use of sound effects—crashing meteorites, screams, Martian machines, and flamethrowers—combined with Welles’s urgent delivery, blurs the line between entertainment and reality. The actors and technical crew craft such a convincing illusion that the alien invasion feels immediate and real, unfolding live in listeners’ living rooms.

Factors Beyond Welles’s Direction Contributed To the Broadcast's Convincingness and Misunderstanding Potential

Radio in 1938 is a relatively new yet deeply trusted medium. Though the first commercial radio station aired only in 1920, by the late 1930s, radio is an essential household fixture and an unrivaled source for news. Its credibility has been cemented by major events and by President Franklin D. Roosevelt’s fireside chats, which bring matters of national importance to Americans in a personal, reassuring manner, establishing radio as the “voice of heaven” and a source of comfort.

Another crucial factor leading to the panic is timing. The Mercury Theater’s War of the Worlds episode airs at 8 p.m., but many listeners tune in late—specifically after finishing a popular comedy show on another channel that ends around 8:12 p.m. These latecomers miss the opening disclaimer, which c ...

The aftermath of the infamous "War of the Worlds" broadcast sees newspapers reporting that Orson Welles and his radio team caused mass hysteria, heart attacks, and even deaths. The press accuses radio of irresponsibility, arguing that radio, as a public medium, must not trick audiences with fictionalized news. This backlash, however, may have deeper roots in the fierce rivalry between newspapers and radio for public attention and advertising revenue in the 1930s.

Newspapers Wanted to Undermine Radio Due to Lost Advertising Revenue and Audience Attention

Press-Radio War: News Reporting Dispute Over Revenue

A few years before the "War of the Worlds" broadcast, the press-radio war erupted as newspapers and radio companies fought bitterly over the right to report news. The Associated Press even stopped providing radio with news stories in an attempt to preserve newspapers' dominance over the news industry. Eventually, a compromise emerged: newspapers sold their stories to radio stations, creating a business arrangement, but underlying tensions remained.

Advertisers Shift Focus to Radio Over Newspapers By 1938

By the late 1930s, radio had quickly become Americans’ main source of news. Advertisers recognized this shift in public attention, increasingly directing their spending toward radio instead of newspapers. The growing prominence of radio represented a clear threat to the newspaper industry’s traditional revenue streams.

Newspapers Would Benefit From a Scandal Showing Radio's Irresponsibility

Against this backdrop, newspapers saw an opportunity to reclaim authority and revenue by seizing on the so-called "panic" triggered by the "War of the Worlds" broadcast. Highlighting this event allowed newspapers to paint radio as reckless and untrustworthy. The incident became a weapon in the ongoing battle, with newspapers eager to hold up radio as an example of a medium that could not be trusted with the public good.

The Newspaper Industry Inflated Minor Incidents Into a Sensational Nationwide Hysteria Narrative to Serve Their Interests

Ap Got Reports of Broadcast Causing Concern, but Newspapers Fabricated Public Panic Stories

Contemporary reports reveal that the Associated Press did receive a few stories of listeners being tricked by the radio play—mainly minor grievances, like anger or confusion. There are anecdotes about police stations in New Jersey being bombarded with calls during the broadcast, but these represent only isolated incidents. No evidence existed of mass panic. Yet conspiracy theorists argue that newspapers took these meager accounts and spun them into a story of widespread chaos, exaggerating the event for their own benefit.

Editor Ben Gross Observed Calm Manhattan Streets, yet Paper Claimed Broadcast Terrorized Nation

Some journalists themselves witnessed a lack of panic firsthand. In his memoir, New York Daily News editor Ben Gross recounts calmly driving through deserted Manhattan streets while "Wa ...

The legend of mass hysteria following Orson Welles's 1938 broadcast of "War of the Worlds" endures, but scrutiny of ratings, listener testimonies, and historical records calls the narrative of widespread chaos into question.

Broadcast Audience Size Smaller Than Narrative Suggests, Contradicting Mass Deception Claims

Despite the popular claim that twelve million people tuned in to hear "War of the Worlds," the actual audience was much smaller. The program managed to capture just two percent of the radio audience that night—a figure far less than commonly cited. This was determined by a 1938 rating system that, unlike today’s anonymous Nielsen ratings, involved direct interviews with 5,000 households about what they were listening to. Among those who reported tuning in, most specified that they were listening to a radio play, the Orson Welles program, or something similar, indicating awareness that it was a piece of fiction, not a real news broadcast. There is no evidence from these interviews that anyone was actually convinced the events were true.

CBS executive Frank Stanton corroborated this, stating that most people didn’t hear the broadcast at all, and those who did thought of it as a prank or entertainment rather than a genuine news alert.

Listener and Journalist Accounts Contradict the Official Panic Narrative

Contemporary reports from listeners and journalists further erode the image of national panic. In Chicago, where the broadcast depicted the city as destroyed by alien invaders, a letter to The Washington Post written in the aftermath describes the scene as calm, noting, "I observe nothing whatsoever of the absurd supposed terror of the populace. There was none."

Similarly, New York Daily News editor Ben Gross, in his memoir, recounts driving through Manhattan while the broadcast claimed the city was being destroyed. He notes that the streets were deserted, but there was no sign of panic or hysteria in the city.

Official records show that, in New Jersey, about 2,000 people called the police during the show, fearing for the safety of their families. However, these were inquiries rather than incidents of mob hysteria or chaos. A letter from the city manager to the FCC calls for regulatory action, but again, there’s no evidence of widespread panic in the public spaces.

Death Claims Linked To the Broadcast Seem Unverified or Fabricated

Stories of deaths stemming from the broadcast, such as heart attacks or suicides, lack solid evidence. While The Washington Post ran stories about a man dying from a heart attack allegedly triggered by the prog ...

The enduring legend of the War of the Worlds panic did not take hold by chance. The collaboration between sensational journalism and questionable academic research created an influential cultural myth that persists today, misleading generations about the reaction to Orson Welles’ 1938 radio broadcast.

Hadley Cantrell's 1940 Book Legitimized a Sensationalized News Story Through Exaggerated Research Methods

Cantrell's Extrapolation of Broadcast Impact on 1.2 Million From 135 Interviews

Princeton professor Hadley Cantrell, a specialist in the effect of radio on public opinion, published his analysis of the War of the Worlds broadcast in the 1940 book The Invasion from Mars. Cantrell claimed the program reached six million people and “frightened” 1.2 million. However, he arrived at this estimate by interviewing only 135 citizens of New Jersey—an extremely small and unrepresentative sample. He then extrapolated from these 100 frightened respondents, asserting they represented a million Americans.

Cantrell Excluded Unafraid or Entertained Listeners

Critics of Cantrell’s methods point out that he intentionally left out those listeners who were unafraid or simply entertained by the broadcast. Moreover, those who did claim to be frightened mostly recalled a fear similar to being startled by a horror movie, not the wild panic or mass hysteria the legend describes. Cantrell’s extrapolation and misinterpretation of his data exaggerated the scale of the panic.

Cantrell Relied On Newspapers' Dubious Accounts and Anecdotal Reports Rather Than Systematic Data Collection, Allowing Sensationalized Journalism Into Academic Literature

Cantrell’s analysis did not end with his interviews. He further relied on newspaper reports and anecdotal accounts—sources that were themselves already sensationalized. At the time, newspapers, still reeling from their press-radio rivalry, seized the opportunity to discredit radio by depicting the broadcast as evidence of radio’s recklessness and inability to distinguish fiction from news. Reports of police stations in New Jersey receiving many calls were amplified, and newspapers portrayed radio as untrustworthy. These dubious accounts were integrated into Cantrell’s academic work, allowing the initially exaggerated news coverage to enter scholarly literature and receive undue legitimacy.

War of the Worlds Shows how Truth-Based Institutions Manipulate Information for Their Interests

The War of the Worlds broadcast illustrates how institutions that are supposed to provide the public with the truth—such as newspapers and researchers—often manipulate information for their own interests. These organizations, entrusted with verifying facts and historical accuracy, were instead the very sources that helped create and spread false narratives about the so-called panic following the broadcast. Despite evidence to the contrary, these institutions promoted the idea of national hysteria, turning what was, for most of the public, a non-event into a mythic episode of mass panic. As a result, public trust in these institutions lent credibility to a false history, embedding it as fact in the collective memory.

Media Practices Mirror Fear-Based Sensationalism of Original War of the Worlds Coverage

Contemporary media continues to mirror the fear-based sensationalism that newspapers engaged in during War of the Worlds coverage. News outlets now routinely use fear-based teasers and dramatic headlines, much like newspapers that sensationalized the radio broadcast to serve their interests. Social media plays an analogous role ...
