The next Doctor is a much bigger global event than the next Bond. The next actor to play the Doctor is literally announced in front of a massive global audience now - in 2013 it got its own half-hour show devoted completely to announcing Peter Capaldi as the next incarnation, and last year they shot a whole reveal video that was aired during a major sporting event revealing the first female Doctor (a gigantic TV event comparable only to the fiftieth anniversary special The Day of the Doctor). James Bond would be lucky to have anything more than a two minute news story on BBC News showing who the next James Bond is.
Doctor Who's fiftieth anniversary had an entire week of TV Specials devoted to it , and a feature-length movie (which sold out immediately in cinemas - not a mean feat when cinema has lost popularity in recent years) with the two most popular Doctors ever to grace screens returning in in David Tennant and Tom Baker, and one of the biggest film stars of all time in the late Sir John Hurt. James Bond's fiftieth anniversary only had one film with no returning James Bonds and a bunch of cheap men's fragrances that probably make you smell nothing like Daniel Craig.
I can name far more who have seen a Doctor Who episode than a James Bond film. Doctor Who is a much bigger global franchise; just look at the number of viewers it attracts worldwide. James Bond has gained more popularity under Daniel Craig, but doesn't attract anywhere near as much media frenzy. James Bond wants to be as popular as Doctor Who, but it will never have a 'James Bond Week' of TV Specials.
