Did You Know....? - Doctor Who

Running on more than 30 seasons, Doctor Who is the longest-running science fiction show in the world and considered the most successful science fiction show of all time based on ratings and sales. In fact, more than 750 episodes have been broadcast since the show started. (Take that Star Trek.)

Even one of the top directors of all time, Steven Spielberg has said that “the world would be a poorer place without Doctor Who.”
