A cliffhanger, or cliffhanger ending, is a plot device in fiction which features a main character in a precarious or difficult dilemma, or confronted with a shocking revelation at the end of an episode of serialized fiction. A cliffhanger is hoped to ensure the audience will return to see how the characters resolve the dilemma.
Some serials end with the caveat "To Be Continued…" or "The End?" In movie serials and television series the following episode sometimes begins with a recap sequence.
The term "cliffhanger" is considered to have originated with the serialised version of Thomas Hardy's A Pair of Blue Eyes (which was published in Tinsley's Magazine between September 1872 and July 1873) in which Henry Knight, one of the protagonists, is left literally hanging off a cliff.
Cliffhangers were especially popular in 1920s and 1930s serials when movie theaters filled the cultural niche later primarily occupied by television. Cliffhangers are often used in television series, especially soap operas that end each episode on a cliffhanger. Prior to the early 1980s, season-ending cliffhangers were rare on U.S. television. The first such season-ender on U.S. TV was in the comedy send-up of soap operas Soap in 1978. Several Australian soap operas, which went off air over summer, such as Number 96, The Restless Years, and Prisoner, ended each year with major and much publicized catastrophe, such as a character being shot in the final seconds of the year's closing episode.
