Torchwood is a British science fiction television programme created by Russell T Davies. The series is a spin-off from the 2005 revival of the long-running science fiction programme Doctor Who. The show has shifted its broadcast channel each series to reflect its growing audience, moving from BBC Three to BBC Two to BBC One, and acquiring U.S. financing in its fourth series when it became a co-production of BBC One and Starz. In contrast to Doctor Who, whose target audience includes both adults and children, Torchwood is aimed at an older audience. Torchwood follows the exploits of a small team of alien-hunters, who make up the Cardiff, Wales branch of the fictional Torchwood Institute, which deals mainly with incidents involving extraterrestrials. Its central character is Captain Jack Harkness (John Barrowman), an immortal former con-man from the distant future; Jack originally appeared in the 2005 series of Doctor Who.
