Doctor timeline for Doctor Who

I have yet to see a full episode of Doctor Who, “the longest-running science fiction television show in the world” but it was apparently really big news that Peter Capaldi is set to be the next regeneration of the character. Capaldi will be the twelfth doctor since the first episode aired in 1963. Out of curiosity, I had a look at past seasons and how some past doctors have crossed paths.

Counting specials and the one television movie, it’s been 800 episodes. Maybe there’s something to this phone booth guy.
