TARDIS stands for Time And Relative Dimension In Space. The TARDIS looks just like a wooden police phone box from the 1950s on the outside, but is of infinite proportions on the inside. This incredible time machine is piloted by the Doctor, a mysterious Time Lord, and is able to transport him anywhere through time and space, disappearing in one place and reappearing somewhere new.
Produced by the BBC, Doctor Who is the longest-running sci-fi TV series in the world. The award-winning show presents the adventures of a time traveler known simply as "the Doctor." Along with his companions, this mysterious Time Lord journeys through time and space using his TARDIS, which appears from the outside to be an ordinary police phone booth.
