A comic book convention or comic-con is an event or gathering with a primary focus on comic books and comic book culture, in which comic book fans gather to meet creators, experts, and each other. Commonly, comic conventions are multi-day events hosted at convention centers, hotels, or college campuses. They feature a wide variety of activities and panels, with a larger number of attendees participating in cosplay than most other types of fan conventions. Comic book conventions are also used as a vehicle for industry, in which publishers, distributors, and retailers represent their comic-related releases. Comic book conventions may be considered derivatives of science-fiction conventions, which began in the late 1930s.
Comic-cons were traditionally organized by fans on a not-for-profit basis, though nowadays most events catering to fans are run by commercial interests for profit. Many conventions have award presentations relating to comics (such as the Eisner Awards, which have been presented at San Diego Comic-Con International since 1988; or the Harvey Awards, which have been presented at a variety of venues also since 1988).
