Fiction generally is a narrative form, in any medium, consisting of people, events, or places that are imaginary—in other words, not based strictly on history or fact. In its most narrow usage, fiction refers to written narratives in prose and often specifically novels, though also novellas and short stories. More broadly, fiction has come to encompass imaginary narratives expressed in any form, including not just writings but also live theatrical performances, films, television programs, radio dramas, comics, role-playing games, and video games.
