"There is nothing wrong with your television set." That famous line opens each episode of the classic science fiction anthology series as part of a narration that makes people think their TVs are being controlled. Episodes of the series, which numbered 49 over the course of two seasons, range from a mix of sci-fi and horror that feature "scary monster" motifs to episodes focused on the sci-fi aspects of the stories. Episode writers include such notables as series creator Leslie Stevens and Harlan Ellison.
