Doctor Who [SEP] Introduction
Doctor Who is a British science fiction television programme produced by the BBC since 1963. The programme depicts the adventures of a Time Lord called "the Doctor", an extraterrestrial being, to all appearances human. The Doctor explores the universe in a time-travelling space ship called the TARDIS. Its exterior appears as a blue British police box, which was a common sight in Britain in 1963 when the series first aired. Accompanied by a number of companions, the Doctor combats a variety of foes while working to save civilisations and help people in need. The show is a significant part of British popular culture, and elsewhere it has gained a cult following.
