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, followed by a third in late 2009. A mini-episode for charity also aired in early 2009. In January 2010 the BBC announced it was looking for a new producer for the series, with season 4 went into production in March 2010.

Premise
The series is set in present-day London and features the adventures of Sarah Jane and adopted son Luke, with friends Maria Jackson Clyde Langer, and Rani Chandra, who was introduced in the second episode of the Series 2, after Maria left the episode before assisted by the super-computer Mr. Smith  as well as 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 DW: The Five Doctors (1983) and in the 2006 episode DW: 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 DW: School Reunion 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, despite the competing spinoff scheduled to debut in 2009, K-9 appeared in the 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 debuted on 15 October 2009, and aired over a period of six weeks (due to the BBC deciding to air two episodes a week). The series received a major ratings boost with a guest appearance by David Tennant as the Doctor, and maintained its momentum throughout the season, consistently scoring higher-than-average viewership for the time period and also scoring high Appreciation Index numbers.

According to Doctor Who Magazine #412, a fourth season is in pre-production as of August 2009. In January 2010 the BBC all but confirmed production of a fourth season by announcing it was seeking a new producer for the series for a March 2010 production start date. Whether this is an indication that Russell T. Davies is no longer involved has yet to be confirmed as of 18 January. Other than this announcement the BBC has, so far, not released any information about the proposed new season, though it is confirmed that all previous cast member of the third series are return, and also return for Fifth series
