Supernatural, which recently aired its landmark 300th episode, currently airs every Thursday. The 15th and final season will roll out this fall.

Supernatural is a series created by Eric Kripke. It was first broadcast on September 13, 2005, on The WB, and subsequently became part of successor The CW’s lineup. Starring Jared Padalecki as Sam Winchester and Jensen Ackles as Dean Winchester, the series follows the two brothers as they hunt demons, ghosts, monsters, and other supernatural beings.
The series is filmed in Vancouver, British Columbia and surrounding areas and was in development for nearly ten years, as creator Kripke spent several years unsuccessfully pitching it. The pilot was viewed by an estimated 5.69 million viewers, and the ratings of the first four episodes prompted The WB to pick up the series for a full season. Originally, Kripke planned the series for three seasons but later expanded it to five. The fifth season concluded the series’ main storyline, and Kripke departed the series as showrunner.
