About 'Doctor Who'
'Doctor Who' depicts the adventures of the Doctor, a Time Lord—a time-travelling humanoid alien. He explores the
universe in his TARDIS, a sentient time-travelling space ship. Its exterior appears as a blue British police box, which
was a common sight in Britain in 1963 when the series first aired. Along with a succession of companions, the
Doctor combats a variety of foes while working to save civilisations and help people in need.
