Dark Skies

Dark Skies is an American UFO conspiracy theory-based sci-fi television series that debuted on NBC on September 21, 1996, and ended on May 31, 1997, and was later rerun by the Sci-Fi Channel; 18 episodes and a two-hour pilot episode were broadcast as a part of NBC's short-lived Thrillogy block. The success of The X-Files on Fox resulted in NBC commissioning this proposed competitor following a pitch from producers Bryce Zabel and Brent Friedman. Its tagline was "History as we know it is a lie."
