Doctor Who has been around for an astonishing 60 years. The story of the Doctor, the Time Lord traveler through time and space, is one of the most flexible and unpredictable shows ever made. It can change genre, setting, and even lead actor from one week to another. The story of its production is almost as interesting as the stories that have made it to the screen, with all sorts of quirks adding to its legend. Unfortunately, part of that legend is the junking of episodes throughout the 1960s and 1970s, when repeats and home media weren’t even a dream.
