what was the prank program about martian invasion

The prank program was Orson Welles’s 1938 radio adaptation of The War of the Worlds , which was staged like a breaking-news broadcast and made many listeners think Mars had actually invaded Earth. It is remembered as one of the most famous media hoaxes in history.

What happened

The program aired on October 30, 1938, as part of The Mercury Theatre on the Air and used a realistic news bulletin style to tell the story. Some listeners tuned in late, missed the opening disclaimer, and believed the emergency reports were real.

Why it spread

The broadcast worked because it sounded urgent and authentic, with fake on- the-spot updates, interruptions, and dramatic reporting. Later accounts estimate that a large number of listeners were frightened, though the exact scale of the panic is debated.

Why people still talk about it

It became a landmark example of how convincing media can shape public belief, and it is still discussed as a classic prank and a warning about misinformation. The central image was simple: “Martians have landed,” but the presentation made it feel immediate and real.

TL;DR: It was Orson Welles’s 1938 War of the Worlds radio drama, presented like real news, which fooled some listeners into thinking a Martian invasion was happening.
