The CW has announced that Supernatural has been renewed for an eighth season. On the air since 2005, the long-running series will be back in 2012-2013 and possibly even longer. There was no word in the network's press release about Season 8 being the show's last.
Also renewed by The CW today were The Vampire Diaries and 90210. The trio of pick-ups leaves the fates of a number of other shows up in the air for now, including The Secret Circle, Nikita, Ringer, Hart of Dixie, and Gossip Girl. While not all the preceding shows will be canceled, it is certain that some will be dropped. News on other renewals is expected later this month at the network's upfront presentation that will take place on May 17, 2012.
