Torchwood started its life on television as a spin-off from Doctor Who, bringing Captain Jack to join new colleagues in a television series that quickly established itself as fresh and watchable television. It's fourth series, subtitled 'Miracle Day', continued its move from the niche channel of BBC3 to metamorphose into an international production between the BBC and the US network Starz. Torchwood has continued to entertain, provoke and attract large audiences and an expanding fandom. This is the first critical celebration of Torchwood across it four series, considering issues of representation, the fandom that surrounds the show and its complex, institutional contexts.Focusing in particular on how the meanings and understandings of cult television have shifted and become subject to technological, industry and marketing changes in recent years, Torchwood Declassified explores topics including the show's aesthetics and branding, its use of tropes from the horror genre, vast tie-in merchandise, status as a spin off, the nature of a celebrity that is both cult and mainstream, as well as the use of sound and music and of cult writers, and Torchwood's connection to place and location. The book will appeal to fans of the series, researchers and scholars, and anyone interested in ongoing questions over what cult television is, what it means, and why it continues to be of importance.
