What sci-fi series is about a man who traveled in a British police box?
"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, from the planet Gallifrey. The Doctor explores the universe in a time-travelling space ship called the TARDIS (Time And Relative Dimension In Space). 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.
