What Is a Convention?
A geek convention is a gathering of fans of specific genres or media — science fiction, gaming, anime, comics, horror — with programming including panels, screenings, competitions, merchandise vendors, artist alleys, and celebrity appearances. Conventions range from local events with a few hundred attendees to massive international events drawing hundreds of thousands. They are the primary physical community gathering for most geek culture segments.
The Major Events
San Diego Comic-Con (SDCC) is the most commercially significant convention — a media industry showcase drawing 130,000+ attendees where major entertainment properties make their biggest announcements. Dragon Con in Atlanta is the largest fan-run convention and is particularly notable for cosplay — its parade is one of the most spectacular annual cosplay displays in the world. PAX (Penny Arcade Expo) is the premier gaming convention family, running multiple events globally. Anime Expo in Los Angeles is the largest anime convention in North America. Comiket in Tokyo dwarfs all of these at 500,000+ attendees across three days.
Convention Etiquette and Safety
The most important convention norm is "cosplay is not consent" — the principle that wearing a costume, however revealing, is not an invitation for touching, unsolicited photos, or unwanted contact of any kind. Asking before photographing someone in cosplay is standard etiquette. Respecting personal space, particularly in crowded spaces with elaborate costumes, is important. Most conventions have explicit harassment policies with enforcement procedures.
The Convention Social Scene
Beyond the programming, conventions are social events — many long-term friendships, relationships, and professional collaborations originate at conventions. The cosplay community in particular has strong in-person social bonds built around shared craft interest. Evening events, room parties (at conventions with attached hotels), and after-parties are as important as daytime programming for the social dimension.
