Taken, also known as Steven Spielberg Presents Taken, is a science fiction miniseries which first aired on the Sci-Fi Channel in 2002 and won an Emmy Award for Outstanding Miniseries. Filmed in Vancouver, British Columbia, Canada, it was written by Leslie Bohem, and directed by Breck Eisner, Félix Enríquez Alcalá, John Fawcett, Tobe Hooper, Jeremy Paul Kagan, Michael Katleman, Sergio Mimica-Gezzan, Bryan Spicer, Jeff Woolnough and Thomas J. Wright. The executive producers were Leslie Bohem and Steven Spielberg. The show takes place from 1944 to 2002 and follows the lives of three families: the Crawfords, who seek to cover up the Roswell crash and the existence of aliens; the Keys, who are subject to frequent experimentation by the aliens; and the Clarkes, who sheltered one of the surviving aliens from the crash. As a result of the decades-long storyline, not a single actor or character appears in every episode of the series. Reception was positive, and the series won an Emmy Award. When the show was launched, the Sci-Fi Channel used the simultaneous establishment of the organization Coalition for Freedom of Information in its promotion campaign. Both the Sci-Fi Channel and the Coalition for Freedom of Information are clients of Washington, D.C. public relations firm PodestaMattoon, and this apparent co-mingling of clients was criticized. The Coalition for Freedom of Information is a group which seeks the release of classified governmental UFO files as well as scientific, congressional, and media credibility for the study of this subject.

Monsters is a syndicated horror anthology series which originally ran from 1988 to 1991 and reran on the Sci-Fi Channel during the 1990s. As of 2011, Monsters airs on NBC Universal's horror/suspense-themed cable channel Chiller in sporadic weekday marathons.In a similar vein to Tales from the Darkside, Monsters shared the same producer, and in some ways succeeded the show. It differed in some respects nonetheless. While Tales sometimes dabbled in stories of science fiction and fantasy, this series was more strictly horror. As the name implies, each episode of Monsters featured a different monster which the story concerned, from the animatronic puppet of a fictional children's television program to mutated, weapon-wielding lab rats.Similar to Tales, however, the stories in Monsters were rarely very straightforward action plots and often contained some ironic twist in which a character's conceit or greed would do him in, often with gruesome results. Adding to this was a sense of comedy often lost on horror productions which might in some instances lighten the audience's mood but in many cases added to the overall eeriness of the production.
