San Diego Comic-Con International is a multi-genre entertainment and comic convention. Originally showcasing primarily comic books and science fiction/fantasy related film, television, and similar popular arts, the convention has since included a larger range of pop culture and entertainment elements across virtually all genres, including 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.”
