While we await "The Day of the Doctor," the BBC invites us to travel back in Doctor Who history with an infographic sure to keep fans busy until they watch the 50th anniversary special.
Head over to the BBC website to play with the infographic, and be sure to click on the dots along the timeline. Up will pop a window for the appropriate Doctor Who story along with the airdate, between which years the Doctor travels, and a relevant clip. It's an easy infograph to get lost in.
