The Doctor Who website seems a bit annoyed with the Guinness Book of World Records. In the 2007 edition, Doctor Who gets the award for ‘Longest-running science fiction TV series’ at 709 episodes (although it’s actually 723 now), but for some reason the ‘Longest-running science fiction TV series (consecutive)’ award goes to Stargate SG-1 at 203 episodes, having previously been held by the X-Files with 202. Before the original run ended in 1989, Doctor Who managed 695 episodes… Perhaps a correction is in order?
