“Doctor Who is a British science fiction television programme produced by the BBC. The programme depicts the adventures of a Time Lord—a time travelling, humanoid alien with two hearts known as the Doctor. He explores the universe in his TARDIS—a sentient,telepathic time machine that flies through time and space. Its exterior appears as a blue British police box, a common sight in 1963, when the series first aired. Along with a succession of companions, the Doctor faces a variety of foes while working to save civilisations, help ordinary people, and right wrongs.” -- Wikipedia
