A fan, or fanatic, sometimes also called aficionado or supporter, is a person who is enthusiastically devoted to something or somebody, such as a band, a sports team, a genre, a book, a movie 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 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 or drawing fan art.
