I thought I'd already posted this, but it seems I hadn't. Hey! Russell T. Davies (perhaps you've heard of him) is no longer unemployed! The big gay Welshman-turned-Los-Angeleno and former showrunner of Doctor Who (perhaps you've heard of it) has announced that a ten episode series of Torchwood will be born from a collaboration between BBC Wales, BBC Worldwide, and American cable channel Starz.
Torchwood made history in 2006 as the first proposed Doctor Who television spin-off to actually happen (previous suggestions, including Jago and Litefoot, K-9 and Company, and Rose Tyler: Earth Defence, thankfully didn't make it very far). As RTD's interviewer in the above link says, the series ran for one season of thirteen episodes on BBC Three, a second season of thirteen on BBC Two, and a mini-series of five episodes shown over five nights (known as Torchwood: Children of Earth) on BBC One. I can't think of another show that could have survived all these format and channel changes and not at all seemed like it was failing. Doctor Who, for instance, would lose the large portions of the general public it relies upon to be considered a success if it started changing around its format. Torchwood can survive with a small fanbase which will follow it wherever, as well as new viewers who've heard it's actually good this season.
