Some major types of fiction include commercial fiction, literary fiction, genre fiction and mainstream fiction. These categories are defined by the audience the fiction is intended for, and some of these broader categories also have sub-divisons.
Commercial fiction is defined as fiction that attracts a broad audience, and it often includes genre fiction such as mystery novels, science fiction novels and fantasy novels. Usually, commercial fiction is written in an accessible and easy-to-read style. Literary fiction, on the contrary, is intended for a smaller audience including academics and other intellectually adventurous readers. Literary fiction novels feature excellent writing and are often more dense than commercial fiction. Mainstream fiction depicts a daily reality that is familiar to most people, and it can include both commercial and literary fiction.
