Fiction is any creative work, chiefly any narrative work, portraying individuals, events, or places that are imaginary or in ways that are imaginary. Fictional portrayals are thus inconsistent with history, fact, or plausibility. In a traditional narrow sense, "fiction" refers to written narratives in prose – often referring specifically to novels, novellas, and short stories. More broadly, however, fiction encompasses imaginary narratives expressed in any medium, including not just writings but also live theatrical performances, films, television programs, radio dramas, comics, role-playing games, and video games. The publishing industry divides fiction into adult fiction, young adult fiction, new adult fiction, and children's fiction.
