The decision to keep Comic-Con at the San Diego Convention Center is scheduled to be formally announced at a news conference Friday. Plans will also be announced for expanding the available space so the popular convention can handle an increasing number of visitors.
Both Los Angeles and Anaheim had submitted bids to try to lure the convention, which draws more than 125,000 people over its four-day run, to leave San Diego.
Comic-Con has been held in San Diego since it started as a comic book fair in 1970. It has since grown into one of the premier popular culture events, featuring hundreds of exhibits, celebrity appearances, Hollywood film premieres and industry panels.
A recent report found that Comic-Con brings almost $163 million annually to San Diego's economy.
In an effort to keep the show in San Diego, officials offered to use $500,000 in hotel taxes to pay for Comic-Con shuttle service around downtown.
