when does torchwood spin off from doctor who
Torchwood Torchwood (UK: /ˈtɔːrtʃˌwʊd/) is a British science fiction television programme created by Russell T Davies. A spin-off from the 2005 revival of long-running science fiction programme Doctor Who, Torchwood aired four series between 2006 and 2011. The show shifted its broadcast channel each series to reflect its growing audience, moving from BBC Three to BBC Two to BBC One, and acquiring US 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. Over its run, the show explored a number of themes; prominent among these were existentialism, homosexual and bisexual relationships, and explorations of human corruptibility.
Tenth Doctor The Tenth Doctor is an incarnation of the Doctor, the protagonist of the BBC science fiction television programme Doctor Who, who is played by David Tennant in three series as well as nine specials. As with previous incarnations of the Doctor, the character has also appeared in other Doctor Who spin-offs. In the programme's narrative, the Doctor is a centuries-old Time Lord alien from the planet Gallifrey who travels in time in his TARDIS, frequently with companions. When the Doctor is critically injured beyond medical repair, he can regenerate his body; in doing so, his physical appearance and personality change, and a new actor assumes the role. Tennant's portrayal of the Doctor is of an outwardly charismatic and charming adventurer whose likable and easygoing attitude can quickly turn to righteous fury when provoked.
