Cosplay Girls, San Diego Comic-Con 2011, California, United States

Originally showcasing comic books, science fiction/fantasy and film/television, and related popular arts, the convention now includes a larger range of pop culture elements, such as horror, animation, anime, manga, toys, collectible card games, video games, webcomics, and fantasy novels. According to Forbes, the convention is the "largest convention of its kind in the world"; it is also the largest convention held in San Diego. In 2010, it filled the San Diego Convention Center to capacity with more than 130,000 attendees which makes it the fourth comic convention in the world for number of attendees, after Comiket, Angoulême International Comics Festival and Lucca Comics and Games.
History and organization
The convention was founded in 1970 by Shel Dorf, Richard Alf, Ken Krueger, Mike Towry, and Greg Bear. Detroit, Michigan-born comics fan Shel Dorf, had in the mid-1960s mounted the Detroit Triple-Fan Fairs, one of the first commercial comics-fan conventions. When he moved to San Diego, California in 1970, he organized a one-day convention (Golden State Comic-Minicon) on March 21, 1970 "as a kind of 'dry run' for the larger convention he hoped to stage." Dorf went on to be associated with the convention as president or manager, variously, for years until becoming estranged from the organization. Alf co-chaired the first convention with Krueger and became chairman in 1971.
