Doctor Who

Launched in November 1963, Doctor Who is a BBC television show about a mysterious traveller who traverses time and space in his ship, the TARDIS (Time and Relative Dimension in Space), which is usually disguised as a Police Telephone Box common across Britain in the 1950s and 60s. Though the show had a lengthy break from the late 1980s to the mid-2000s, it continues to be produced today, with the concept of regeneration allowing new actors to take over the leading role every few years.

Doctor Who has been represented in comic strips virtually continuously since shortly after its inception, and has also enjoyed (loosely-adapted) cinematic movies, hundreds of tie-in novels, official audio plays with past cast members reprising their original roles, and cartoons. There have also been several spin-offs in almost all of these media, beginning with his greatest enemy, the Daleks, who actually got their own comic strip before the Doctor did.
