A fansite, fan site, fan blog or fan page is a website created and maintained by a fan or devotee about a celebrity, thing, or particular cultural phenomenon.
Fansites may offer specialized information on the subject (e.g., episode listings, biographies, storyline plots), pictures taken from various sources, the latest news related to their subject, media downloads, links to other, similar fansites, and the chance to talk to other fans via discussion boards. They often take the form of a blog, highlighting the latest news regarding the fansite subject. They often include galleries of photos or videos of the subject and are often "affiliates" with other fansites.
Fanlistings are another common type of unofficial fansite, though they are much simpler than general fansites, and are designed simply to list fans of a certain subject who have chosen to submit their names (and sometimes links to their home pages). Many do not contain much information on the subject at all, aside from a small introduction. They are generally made with the thought that visitors will already have knowledge of the subject. However, several are a part of a bigger fansite, used to amplify the fanbase's experience.
