When Supernatural was created by Eric Kripke back in 2005, he'd originally planned the series for three seasons but later expanded it to five. The fifth season began airing on September 10, 2009, and concluded the series' main storyline.
However the CW officially renewed the show for a sixth season on February 16, 2010. This continued and on February 13, 2014 the CW renewed the series for a tenth season.
