San Diego Comic-Con International, also known as Comic-Con International: San Diegoand commonly known as Comic-Con or the San Diego Comic-Con, was founded as the Golden State Comic Book Convention and later the San Diego Comic Book Convention in 1970 by Shel Dorf and a group of San Diegans. It is traditionally a four-day event (Thursday through Sunday — though a three-hour preview night on Wednesday is open to professionals, exhibitors, and some guests pre-registered for all four days) held during the summer in San Diego, California, United States, at the San Diego Convention Center. Comic-Con is both the name of the annual event and the common name of the organization.
Originally showcasing comic books, science fiction/fantasy and film/television (as was evident by the three circled figures appearing in Comic-Con's original logo), and related popular arts, the convention has expanded over the years to include a larger range of pop culture elements, such as horror, anime, manga, animation, toys, collectible card games, video games, webcomics, and fantasy novels. The convention is the largest in the Americas, and fourth largest in the world after the Comiket in Japan, the Angoulême International Comics Festival in France, and the Lucca Comics and Games in Italy, filling to capacity the San Diego Convention Center with over 125,000 attendees in 2007.
