The Sarah Jane Adventures

The Sarah Jane Adventures is a spin-off series, produced by BBC Wales for CBBC, starring Elisabeth Sladen and created by Russell T Davies. The programme focuses on the adventures of investigative journalist Sarah Jane Smith. The series debuted on BBC One with a 60-minute special on 1st January 2007. A full series of ten 30-minute episodes followed later in the year. A second season aired in the fall of 2008, with a third season commissioned for the fall of 2009. CBBC announced that Series 3 will debut on 15 October 2009, starting with the episode, Prisoner of the Judoon. Series 3 actually made its debut on this date on BBC1. 

Premise
The series is set in present-day West London and features the adventures of Sarah Jane and adopted son Luke, with friends Maria Jackson(Series One), Clyde Langer, and Rani Chandra(Series Two and Three), assisted by the super Computer Mr Smith (which is also a Xylok), as well as sometimes K-9.

Production team
The executive producers for The Sarah Jane Adventures are Davies and Julie Gardner. Susie Liggat produced Invasion of the Bane, but Matthew Bouch produced the series; Phil Collinson held the title of Series Producer. Gareth Roberts, writing in Doctor Who Magazine, said, "We're all determined that this will be a big, full-blooded drama; that nobody should ever think of it as 'just' a children's programme."

Development
In 2006, Children's BBC expressed an interest in producing a Doctor Who spin-off. Their initial idea was "a drama based on the idea of a young Doctor Who", but Russell T. Davies vetoed this. "Somehow, the idea of a fourteen-year-old Doctor, on Gallifrey inventing sonic screwdrivers, takes away from the mystery and intrigue of who he is and where he came from," said Davies. He suggested instead a series based on the Doctor's former companion Sarah Jane Smith.

The character of Sarah Jane, played by Sladen, appeared in Doctor Who from 1973 to 1976, alongside Jon Pertwee as the Third Doctor, and later Tom Baker as the Fourth Doctor. A pilot for another Doctor Who spin-off series, K-9 and Company, made in 1981, featured Sarah Jane and the robot dog K-9; however, the option to make a series was not picked up. Sarah Jane and K-9 returned to Doctor Who in various media many times over the years, most notably in the 20th anniversary special The Five Doctors (1983) and in the 2006 episode School Reunion -- both of which acknowledged the existence of K-9 and Company within the canon of the Whoniverse by showing Sarah Jane in possession of K-9 as established in the 1981 pilot episode. Reports of a spin-off series first appeared around the time of School Reunion's original airing, with the series having the working title of Sarah Jane Investigates.

K-9 — now K-9 Mark IV — appeared only twice in the first season: during the pilot episode, and again briefly during the season finale, The Lost Boy (as well as a brief appearance in DW: Journey's End). The decision not to feature K-9 was due to the concurrent development of the television series K-9, which is not associated with the BBC and will not feature any Doctor Who connections beyond K-9 himself. However it has been announced that, despite the competing spinoff scheduled to debut in 2009, K-9 will appear in the upcoming third season.

In February 2009 the BBC announced that a mini-episode of The Sarah Jane Adventures would air on 13 March 2009 as part of Comic Relief's Red Nose Day appeal. This makes SJA the first of the franchise spin-offs to spawn a mini-episode; to date there have been three produced for Doctor Who itself.

In a speech to members of BAFTA in March 2009, Davies revealed that production of Series 3 had nearly been cancelled on three occasions due to budget cuts to children's programming at the BBC.

Series 3 began airing on 15 October 2009. According to Doctor Who Magazine #412, a fourth season is in pre-production as of August 2009, but has yet to be officially commissioned.

Novelisations
Although the BBC has so far (as of 2008) refrained from commissioning novelisations based upon episodes of the revived Doctor Who or Torchwood, all of the serials from the first series of The Sarah Jane Adventures have been adapted as novels by Penguin Character Books, including volumes written by stalwarts Terrance Dicks and Gary Russell, marking the most intense period of episode novelisations since the end of the Target Books era in the early 1990s. As of spring 2009 two novelisations based upon Series 2 stories have been published, with no announcement as to whether more novelisations or original novels are planned.

Two audio stories were released by BBC Audiobooks in November 2007 The Glittering Storm by Stephen Cole and The Thirteenth Stone by Justin Richards.
