The annual geek gathering and Mayor Jerry Sanders announced today that Comic-Con has extended its stay in San Diego one more year. Comic-Con had been contractually committed to remain at the San Diego Convention Center until 2015, and event organizers had indicated they might leave their long-time home if an expansion of the Convention Center did not occur. While building has not started, the city today committed to a $500 million plan. Comic-Con was started in 1970 as the Golden State Comic Book Convention. The July gathering now attracts more than 130,000 attendees and has proven an important marketing launchpad for studios and broadcasters. Comic-Con 2013 is scheduled to run July 18-21.
