The world of Classic Doctor Who, an epic cornerstone of sci-fi television that spans twenty-six seasons and over 150 serials, is a rather expansive one. Seven Doctors (eight with the TV movie), nearly two dozen companions, planets by the score, and more aliens than you can shake a sonic screwdriver at. The new series is fantastic, but there's a lot more where that came from. Let's dive right in, shall we?In this first volume of Twitter Who, Hannah J. Rothman takes on the complete William Hartnell era of Doctor Who (1963-1966) armed only with her trusty Twitter account and a fresh eye on old adventures. It's a New Whovian's journey through Classic territory, 140 characters at a time.
