The Torchwood Archive is out today; a two-hour celebration of the tenth anniversary this weekend of the hugely popular Doctor Who spin-off, starring John Barrowman, Eve Myles, Gareth David-Lloyd, Naoko Mori, and a host of other familiar names. It also features Samuel Barnett as Norton Folgate, who this weekend debuts on BBC America as Douglas Adams' Dirk Gently in a new TV series!

And to further mark this anniversary, until 23:59 next Friday (UK time), Big Finish are offering a 15% discount on the first 12 of the Torchwood single disc releases, including such titles as The Conspiracy, Fall to Earth, More Than This, Zone 10, Moving Target and many more. Enter a discount code of 15OFFTW on check-out to have the discount applied to these individual titles, or go for the six-story Torchwood bundles for the first 12 releases which have been reduced in price for the weekend (note: discount codes don't apply to subscriptions, bundles and pre-orders).

The Torchwood Archive is available from today on Download and CD, the pre-release prices of £11.99 and £13.99 being held until the end of 2016. The 15% offers end at 23:59 (UK time) on Friday 28th October. If you have Android or Apple devices and want to listen to your purchases on-the-go, try the free Big Finish apps.

Big Finish's Torchwood ranges continue with more thrilling and intriguing single-disc stories from March, and with next month's Torchwood - Outbreak and January's Torchwood One - Before The Fall (both currently at pre-release prices).

Happy Tenth Birthday Torchwood!
