User:Aurelian Carpathia/Whoniverse chronology

Since the premiere of Doctor Who on British television in 1963, hundreds of stories have aired in the main series, plus many hundreds more told across various media. While some fans consider only televised stories - with a few notable exceptions - plus some webcasts canonical, the BBC's official stance is steadfastly ambiguous, and televised/webcast Who directly references other media on occasion, as exemplified in Rose Tyler's mention in the episode "Boom Town" of a stellar system she visited in the New Series Adventures novel The Monsters Inside, and the Eighth Doctor's recollection in a fiftieth anniversary prequel minisode of past companions who appeared only in audio productions. With multiple spin-off series, licensees, formats, and an ever-changing roster of contributors, the Whoniverse is highly complex a half century on, and the unusual temporal fluidity inherent in the Doctor's journeys in the TARDIS - as well as the relative unconcern many principal storytellers exhibit toward continuity - further compounds the already substantial difficulty of assembling a cohesive, comprehensive canon. However, many stories are placeable with varying degrees of precision according both to explicit publisher statements such as those offered by Big Finish Productions, and by identifying relevant narrative markers; this article attempts to tentatively chronologize all licensed Whoniverse stories accordingly.
