“The last show left to originally air on The WB, Supernatural has had an impressively long life, and is now in Season 9. The show not only continues to be one of the strongest performers on The CW, but its ratings have been up this season from the previous year. Still, just how much longer could the series go?
Asked that question at the TCA (Television Critics Association) press tour today, CW’s president, Mark Pedowitz, essentially said the show could go on indefinitely – as long as the ratings continue to hold up and the Supernatural team wants to continue.”
