The quite simple answer to that question is, it is a place where people who love comic books go to meet other people who love comic books. They swap, buy and play “I’ll show you mine of you show me yours”. Kind of like a swinger’s party only with less extroverts and sex. At least that’s how it was originally conceived. These days it has taken on much more and a broader influence of pop culture in general.
Comic-Con is the common name for the San Diego Comic-Con International, which takes place on an annual basis in San Diego, California. Comic-Con is an increasingly popular convention, which is aimed at fans of comic books, science fiction, horror and much more. There are many Comic Con events around the world now. The San Diego event is the largest inside the States, having been first held almost thirty five years ago. Today there are many more that stretch across, not only the United States, but also around the globe in countries like Australia, Canada, the United Kingdom, Romania, Russia, India and the United Arab Emirates.
It was founded way back in 1970 as the Golden State Comic Book Convention by a group of people from San Diego, which included Shel Dorf, Richard Alf, Ken Krueger and Mike Towry. Later on, it became known as the "San Diego Comic Book Convention". On the website, its name is Comic-Con International: San Diego however, it is more commonly known simply as Comic-Con or the San Diego Comic-Con or "SDCC".
