fan convention

A fan convention, or con, is an event in which the fans of a particular TV show, comic book, or actor, or an entire style of entertainment such as science fiction or anime, gather together to meet famous personalities (and each other) face-to-face. The actors often give out free autographs to the fans, perhaps in exchange for a flat appearance fee, and sometimes may perform songs that have no relevance to the shows so as to entertain the fans. Such conventions are usually quite expensive and are hosted in hotels. There is often tight security for the celebrities to protect against potentially fanatic fans. (It should be noted that such features are not common at traditional science fiction conventions, which are more oriented towards science fiction as a mode of literature, rather than towards visual media, and do not include any paid appearances by famous personalities.)
