Poltergeist: The Legacy is a Canadian/American horror television series which ran from 21 April 1996 to 12 November 1999. Despite the Poltergeist name, there seems to be no real connection between the show and the original film trilogy, aside from it being intended as a spin-off from them. Poltergeist: The Legacy debuted on Showtime, which showed the first three seasons. After Showtime cancelled the show the rights were purchased by the Sci-Fi Channel, which continued the series for another season. Adapted from the Wikipedia article on Poltergeist: The Legacy.
