“Supernatural” revolves around the story of two brothers Sam and Dean as they hunt demons, ghosts, monsters and other supernatural beings in the world. The series is produced by Warner Bros Television, in association with Wonderland Sound and Vision.
The series’ pilot episode was viewed by an estimated 5.69 million viewers and the high ratings for the first four episodes of “Supernatural” prompted the network to pick up the series for a full season.
Creator Eric Kripke was only planning three seasons for “Supernatural” but because it became such a monster hit, he expanded it to five that is why Season 5 concluded the show’s main storyline. Kripke has since left the series as showrunner and the slot was picked up by Sera Gamble and Jeremy Carver as co-creators and executive producers.
