Beloved teen soap The O.C. has been canceled due to falling ratings following actress Mischa Barton's decision to quit the show. The once hit series joins former Will & Grace star Megan Mullally's new chat show as the first TV casualties of the new year in America. Mullally's much-criticized show will end immediately, while The O.C. will see out its current season. The final episode of the series will air on February 22. In a statement released yesterday, The O.C. creator Josh Schwartz said, "It has been an amazing experience and a great run. For a certain audience, at a certain time, The O.C. has meant something. For that we are grateful."
