Fandom in the context of "Madonna fandom"

A fan or fanatic, sometimes also termed an aficionado or enthusiast, is a person who exhibits strong interest or admiration for something or somebody, such as a celebrity, a sport, a sports team, a genre, a politician, a book, a television show, a movie, a video game or an entertainer. Collectively, the fans of a particular object or person constitute its fanbase or fandom. They may show their enthusiasm in a variety of ways, such as by promoting the object of their interest, being members of a related fan club, holding or participating in fan conventions or writing fan mail. They may also engage in creative activities ("fan labor") such as creating fanzines, writing fan fiction, making memes, drawing fan art, or developing fan games. Some excessively avid fans are called "stans" (a portmanteau of stalker and fan).

A convention (or event), in the sense of a meeting, is a gathering of individuals who meet at an arranged place and time in order to discuss or engage in some common interest. The most common conventions are based upon industry, profession, and fandom. Trade conventions typically focus on a particular industry or industry segment, and feature keynote speakers, vendor displays, and other information and activities of interest to the event organizers and attendees. Professional conventions focus on issues of concern along with advancements related to the profession. Such conventions are generally organized by societies or communities dedicated to promotion of the topic of interest. Fan conventions usually feature displays, shows, and sales based on pop culture and guest celebrities. Science fiction conventions traditionally partake of the nature of both professional conventions and fan conventions, with the balance varying from one to another. Conventions also exist for various hobbies, such as gaming or model railroads.

Conventions are often planned and coordinated, often in exacting detail, by professional meeting and convention planners, either by staff of the convention's hosting company or by outside specialists. Most large cities will have a convention center dedicated to hosting such events. The term MICE (Meetings, Incentives, Conferencing, Exhibitions) is widely used in Asia as a description of the industry. The Convention ("C") is one of the most dynamic elements in the M.I.C.E. segment. The industry is generally regulated under the tourism sector.

A cult following is a group of fans who are highly dedicated to a person, idea, object, movement, or work, often an artist, in particular a performing artist, or an artwork in some medium. The latter is often called a cult classic. A film, book, musical artist, television series, or video game, among other things, is said to have a cult following when it has a 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 eccentric or anti-establishment to be appreciated by the general public or to be widely commercially successful.

A cult film, also commonly referred to as a cult classic, is a film that has acquired a cult following. Cult films are known for their dedicated, passionate fanbase, which forms an elaborate subculture, members of which engage in repeated viewings, dialogue-quoting, and audience participation. Inclusive definitions allow for major studio productions, especially box-office bombs, while exclusive definitions focus more on obscure, transgressive films shunned by the mainstream. The difficulty in defining the term and subjectivity of what qualifies as a cult film mirror classificatory disputes about art. The term cult film itself was first used in the 1970s to describe the culture that surrounded underground films and midnight movies, though cult was in common use in film analysis for decades prior to that.

Cult films trace their origin back to controversial and suppressed films kept alive by dedicated fans. In some cases, reclaimed or rediscovered films have acquired cult followings decades after their original release, occasionally for their camp value. Other cult films have since become well-respected or reassessed as classics; there is debate as to whether these popular and accepted films are still cult films. After failing at the cinema, some cult films have become regular fixtures on cable television or profitable sellers on home video. Others have inspired their own film festivals. Cult films can both appeal to specific subcultures and form their own subcultures. Other media that reference cult films can easily identify which demographics they desire to attract and offer savvy fans an opportunity to demonstrate their knowledge.

A fan convention (abbreviated con) is an event in which fans of a particular topic gather to participate in discussions and activities related to their shared interests. Fan conventions are typically organized around specific fandoms, genres, or media franchises, with distinct conventions dedicated to them. The concept of a fan convention has existed since at least 1942 and has evolved into an important part of modern popular culture.

Conventions can be grassroots events organized by volunteer fan communities on a nonprofit basis, commercial enterprises that generate profit through ticket sales and celebrity appearances, or both. Science fiction conventions, which emerged in the late 1930s, established the template that spawned numerous specialized convention types, including those dedicated to anime and manga, tabletop and video gaming, comics, and various subcultures like the furry fandom and the My Little Pony fandom (also known as the brony fandom).

Science fiction fandom or SF fandom is a community or fandom of people interested in science fiction in contact with one another based upon that interest. SF fandom has a life of its own, but not much in the way of formal organization (although formal clubs such as the Futurians (1937–1945) and the Los Angeles Science Fantasy Society (1934–present) are recognized examples of organized fandom).

Most often called simply "fandom" within the community, it can be viewed as a distinct subculture, with its own literature and jargon; marriages and other relationships among fans are common, as are multi-generational fan families.

In the entertainment industry, a sleeper hit refers to a film, television series, music release, video game or other entertainment product that was initially unsuccessful on release, but eventually became a surprise success. A sleeper hit may have had little to no promotion or lack a successful launch, but gradually develops a fandom and spreads via word of mouth, media coverage or unexpected internet virality. As Variety puts it, "A 'sleeper hit' can be defined as the kind of show that catches us by surprise—programs whose popularity grows over time and can ultimately outshine the preordained hits."

A sleeper hit often lacks star performers or high production values, but prevails, at times against its makers' expectations, on the strength of such qualities as narrative, approach or novelty, as well as market accidents. Sleeper hit films benefit theater owners because they keep a larger percentage of the money from ticket sales.
