The programme depicts the adventures of a Time Lord called "The Doctor", an extraterrestrial being from the planet Gallifrey. He 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 Time Lords are a fictional, ancient extraterrestrial people in the British science fiction television series "Doctor Who", of which the series' protagonist, the Doctor, is a member. Time Lords are so named for their command of time travel technology and their non-linear perception of time. Originally they were described as a powerful and wise race from the planet Gallifrey, from which the Doctor was a renegade; details beyond this were very limited for the first decade of the series. They later became integral to many episodes and stories as their role in the fictional universe developed. For the first eight years after the series resumed in 2005, the Time Lords were said to have been destroyed at some point between the original series' cancellation in 1989 and the show's revival during the fictional Last Great Time War. In 2013, the 50th anniversary special "The Day of the Doctor" concerned this supposed destruction and their eventual survival.  - Broadcasting House is the headquarters of the BBC, in Portland Place and Langham Place, London.

It is a Grade II* listed building and includes the BBC Radio Theatre, where music and speech programmes are recorded in front of a studio audience, and lobby that was used as a location for filming the 1998 BBC television series "In the Red".
