The show has received recognition from critics and the public as one of the finest British television programmes, including the 2006 British Academy Television Award for Best Drama Series and five consecutive (2005–10) wins at the National Television Awards under Russell T Davies' reign as Executive Producer. In 2011, Matt Smith became the first Doctor to be nominated for a BAFTA Award for Best Actor in a Leading Role. The programme is listed in the Guinness World Records as the longest-running science fiction television show in the world and as the "most successful" science fiction series of all time—based on its over-all broadcast ratings, DVD and book sales, and iTunes traffic. During its original run, it was recognised for its imaginative stories, creative low-budget special effects, and pioneering use of electronic music (originally produced by the BBC Radiophonic Workshop). The show is a significant part of British popular culture; and elsewhere it has become a cult television favourite. The show has influenced generations of British television professionals, many of whom grew up watching the series. The programme originally ran from 1963 to 1989. After an unsuccessful attempt to revive regular production in 1996 with a backdoor pilot in the form of a television film, the programme was relaunched in 2005, produced in-house by BBC Wales in Cardiff. Series 1 in the 21st Century, featuring Christopher Eccleston as the ninth incarnation, was produced by the BBC. Series 2 and 3 had some development money contributed by the Canadian Broadcasting Corporation (CBC), which was credited as a co-producer. Doctor Who also spawned spin-offs in multiple media, including Torchwood (2006), The Sarah Jane Adventures (2007), K-9 (2009), P.R.O.B.E. (video series), and a single pilot episode of K-9 and Company (1981). The Doctor has been principally played by eleven actors. The transition from one actor to another is written into the plot of the show as regeneration, whereby the character of the Doctor takes on a new body and, to some extent, new personality. Although each portrayal is different, and on occasions the various incarnations have even met one another, they are all meant to be aspects of the same character. The Doctor is currently portrayed by Matt Smith, who took up the role after David Tennant's final appearance in an episode broadcast on 1 January 2010. Series 5 of the relaunched programme was first broadcast in 2010, in which the Eleventh Doctor is accompanied by Amy Pond (Karen Gillan), who is joined later in the series by fiancé (later husband) Rory Williams (Arthur Darvill). This was followed by the Series 6 in 2011, with Darvill appearing as a regular companion. A seventh series, scheduled to begin broadcast in late 2012, entered production in February 2012. The series will mark its 50th anniversary in 2013.
