Chronology and canonicity

Since the creation of the Doctor Who character by BBC Television in the early 1960s, a myriad of stories have been published about Doctor Who, in different media: apart from the actual television episodes that continue to be produced by the BBC, there have also been novels, comics, short stories, audio books, radio plays, interactive video games, game books, webcasts, DVD extras, and stage performances. The BBC takes no position on the canonicity of any of such stories, and producers of the show have expressed distaste for the idea of canonicity.
