Read This: The night the BBC’s Halloween stunt went terribly wrong

In 1988, screenwriter Stephen Volk had an idea for a show that would give viewers a good scare while satirizing the television industry at the same time. He proposed to the BBC a fictional series about “a roving paranormal investigation crew that climaxes in a live tour of a supposedly haunted house.” The wary BBC gave the go-ahead for a single, 90-minute broadcast, and the result finally aired on Halloween night in 1992 as Ghostwatch. As Jake Rossen reveals in a grimly fascinating article for Mental Floss, the program was far more effective on the audience than anyone involved could have guessed. Children lost sleep. A woman went into labor from stress. One man soiled himself. And a traumatized 18-year-old was allegedly driven to suicide. Nearly three years later, England’s Broadcasting Standards Council ruled that the BBC had acted irresponsibly in airing the program while not making it clear enough to viewers that the proceedings were fictional.
