. . "Dark Skies is an American UFO conspiracy theory\u2013based sci-fi television series (1996\u201397) for 18 episodes, and a two-hour pilot episode. The success of The X-Files on Fox proved there was an audience for science fiction shows, resulting in NBC commissioning this proposed competitor following a pitch from producers Bryce Zabel and Brent Friedman. The series debuted September 21, 1996, on NBC, and was later rerun by the Sci-Fi Channel. Its tagline was \"History as we know it is a lie.\""@en . . "1997-05-31Z"^^ . "20"^^ .
