They may dart liberally across space and time, but when it comes to screen time, each successive Doctor Who has a very finite tenure on the show. So who's had the keys to the Tardis the longest?
The chart below, torn from the pages of Time & Space Visualiser: The Story and History of Doctor Who as Data Visualisations, reveals all. Designed by Paul Smith, it sees the fourth Doctor -- fan favourite Tom Baker -- way out in front with 71 hours and 37 minutes of screen time. Eighth Doctor, Paul McGann (who only got a single made-for-TV movie) was the shortest lived of all Doctors, with just 1 hour and 4 minutes. Will the next Doctor, Peter "Swear-y Malcolm Tucker" Capaldi, outlive them all as the show's 50th anniversary episode approaches?
