Background

Doctor Who is a BBC Science-fiction programme built around the Doctor’s travels through time and space. The TARDIS carries the Doctor on those journeys. The opening story, An Unearthly Child, introduced the Doctor through Susan Foreman and her teachers, Ian Chesterton and Barbara Wright. William Hartnell played the first Doctor when the programme began in 1963. [Official story guide](https://www.doctorwho.tv/stories/an-unearthly-child).

The programme uses regeneration to explain changes in the Doctor’s form. It enables the Doctor to take a new physical form, with changes in personality as well as appearance. Memories carry between incarnations, preserving the identity of the traveller across those changes. The combination of regeneration, companions and journeys in the TARDIS gives the drama continuity across different characters and settings.
