And my Who fanboisim isn't affected, since the Doctor isn't actually called 'Doctor Who' (save for the credits in the non-canonical Peter Cushing movies, I believe).

He was credited as 'Doctor Who' from 1963 - 1979 (according to IMDB). I think 'Doctor Who' was also used for Sylvester McCoy's Doctor.
