The first episode of the scary-monster show “Supernatural,” in which a college student came home and found his girlfriend on the ceiling, roasting like a blond marshmallow, was shown by the WB network on Sept. 13, 2005.
Since then quite a few shows have come and gone — “Breaking Bad,” “Friday Night Lights,” “30 Rock,” “Dexter,” to name a few — but “Supernatural” is still here, now on CW on Tuesday nights. Midway through its ninth demon-stabbing, vampire-decapitating, angel-ganking season, it’s the sixth-longest-running drama currently in prime time — and it’s already been renewed for another season.
