The British Broadcasting Corporation (BBC) is the dominant television and radio broadcast entity in the United Kingdom. Currently, the BBC operates multiple TV networks and radio stations, many of which have broadcast Doctor Who-related content over the years.

Its main television channel is currently known as BBC One. Doctor Who aired on BBC One since its inception in 1963. From 1992, BBC Two aired reruns of earlier stories as well as Doctor Who: Chapter One - Remastered from 2000-2003 and from 1998 to 2016, digital channel BBC Choice (later BBC Three from 2003) repeated episodes from Season 35 onwards the day after its first transmission. BBC Four aired the foreign adaptations beginning in 2018.
