Doctor Who (1963) Season 1 | Science fiction

Doctor Who is a British science fiction television series broadcast by the BBC since 1963. The series, created by Sydney Newman, C. E. Webber and Donald Wilson, depicts the adventures of an extraterrestrial being called the Doctor, part of a humanoid species called Time Lords. The Doctor travels in the universe and in time using a time travelling spaceship called the TARDIS, which externally appears as a British police box. While travelling, the Doctor works to save lives and liberate oppressed peoples by combating foes. The Doctor usually travels with companions.

Beginning with William Hartnell, fourteen actors have headlined the series as the Doctor; the most recent being Ncuti Gatwa, who portrayed the Fifteenth Doctor from 2023 to 2025.[2] The transition between actors is written into the plot of the series with the concept of regeneration into a new incarnation, a plot device in which, when a Time Lord is fatally injured or weakened from old age, their cells regenerate and they are reincarnated into a different body with new mannerisms and behaviour but the same memories. This explains each actor's distinct portrayal, as they all represent different stages in the Doctor's life and, together, form a single lifetime with a single narrative. The time-travelling nature of the plot means that different incarnations of the Doctor occasionally meet. The Doctor can change ethnic appearance or gender; in 2017, Jodie Whittaker became the first woman cast in the lead role, and in 2023, Gatwa became the first black actor to lead the series.

The series is a significant part of British popular culture and has gained a cult following overseas. It has influenced generations of British television professionals, many of whom grew up watching the series. Fans of the series are sometimes referred to as Whovians. The series has been listed in Guinness World Records as the longest-running science-fiction television series in the world, as well as the "most successful" science-fiction series of all time, based on its overall broadcast ratings, DVD and book sales.

The series originally ran from 1963 to 1989. There was an unsuccessful attempt to revive regular production in 1996 with a backdoor pilot in the form of a television film titled Doctor Who. The series was relaunched in 2005 and was produced in-house by BBC Wales in Cardiff.[g] Since 2023, the show has been co-produced by Bad Wolf and BBC Studios Productions in Cardiff. Doctor Who has spawned numerous spin-offs as part of the Whoniverse, including comic books, films, novels and audio dramas, and the television series Torchwood (2006–2011), The Sarah Jane Adventures (2007–2011), K9 (2009–2010), Class (2016), Tales of the TARDIS (2023–2024), and the upcoming The War Between the Land and the Sea. It has been the subject of many parodies and references in popular culture.
