Cult hit

A cult following is a group of fans who are highly dedicated to a work of culture. A film, book, musical artist, television series or video game, among other things, will be said to have a cult following when it has a small but very passionate fanbase. A common component of cult followings is the emotional attachment the fans have to the object of the cult following, often identifying themselves and other fans as members of a community. Cult followings are also commonly associated with niche markets. Cult media are often associated with underground culture, and are considered too or subversive to be appreciated by the general public or to be commercially successful.

Many cult fans express a certain irony about their devotion. Sometimes, these cult followings cross the border to camp followings. Fans may become involved in a subculture of fandom, either via conventions, online communities or through activities such as writing series-related fiction, costume creation, replica prop and model building, or creating their own audio or video productions from the formats and characters.

There is not always a clear difference between cult and mainstream media. Franchises such as Star Trek, Star Wars, Doctor Who, Harry Potter, The Lord of the Rings, Game of Thrones, Clueless and Mean Girls attract mass audiences but also have core groups of fanatical followers. Professors Xavier Mendik and Ernest Mathijs, authors of 100 Cult Films, argue that the devoted following among these films make them cult classics. In many cases, films that have cult followings may have been financial flops during their theatrical box office run, and even received mixed or mostly negative reviews by mainstream media, but still be considered a major success by small core groups or communities of fans devoted to such films.
