he O.C. is an American teen drama television series that originally aired on the FOX network in the United States from August 5, 2003, to February 22, 2007, running a total of four seasons. The series, created by Josh Schwartz, portrays the fictional lives of a group of teenagers and their families residing in Newport Beach in Orange County, California. The O.C. has been broadcast in more than 50 countries worldwide and was one of the most popular new dramas of 2003. The O.C. attracted a strong 9.7 million viewers for its first season, but ratings declined as the show went on. The low ratings led to cancellation in early 2007, after four seasons, and 92 episodes, even after an online petition which gained over 700,000 signatures. Re-runs of The O.C. are now shown in syndication on SOAPnet, MuchMusic and Channel 4.
