A $753 million expansion of San Diego's convention center aimed at holding on to Comic-Con and other shows has been proposed by that city's port and convention officials, with approval by the Port Commission expected Tuesday.

The move would sweeten the pot for a capacity Comic-Con that has threatened to take its business — including 126,000 attendees and millions of dollars in tourist spending — to Los Angeles, Anaheim or Las Vegas as it outgrows the San Diego facility, according to the San Diego Union-Tribune. The expansion, however, wouldn't open until 2015, according to the paper, casting doubt as to whether it will sway the organizers of the pop culture phenomenon that draws Hollywood interest each summer.

The 300,000 square foot addition to the convention center along San Diego's harbor has been sought for nearly a decade, according to the U-T, because the convention center has been operating at capacity since 2001.

Comic-Con has not only outgrown those digs down south, but it has been increasingly patronized by Hollywood players who seek out franchise brands that the film industry has heavily depended on in recent years. A move to L.A. or Anaheim would bring Comic-Con closer to the film world.
