BBC sci-fi series 'Doctor Who' was first broadcast on BBC One at 5.15pm on Saturday November 23, 1963. It was created as an educational family show to fit between the football results and evening entertainment programmes. Doctor Who was the brainchild of Canadian TV producer and BBC Head of Drama, Sydney Newman. The fiftieth anniversary special episode of the long-running series is 'The Day of the Doctor', which will be screened simultaneously in 76 countries on 23 November 2013 and will be the world's biggest drama simulcast.

This image is of actor Jon Pertwee, who played the Third Doctor for five seasons from 3 January 1970 to 8 June 1974. Pertwee played the character as an active, suave and technologically oriented crusader. The Third Doctor came into existence as part of a punishment from his own race, the Time Lords, who forced him to regenerate and disabled his TARDIS. As a result he spent much time stranded on Earth, where he worked as a scientific advisor to British military organisation, UNIT. Eventually this restriction was lifted and he embarked on more traditional time travel and space exploration stories. In 1983 Pertwee appeared again as the Third Doctor in the 20th anniversary special episode 'The Five Doctors', and then finally in a charity special episode 'Dimensions in Time' in 1993.

This image of Pertwee as Dr Who is from the New Zealand Post Archives series, which was part of the Post Office Museum and Archives. There is a large amount of photographic and audio visual material in this series, which were intended for publicity, internal training, and to show NZ Post history. This photograph is likely to have been commissioned for publicity purposes in conjunction with Telecom.
