Memorable product tie-in: The Daleks, mutant nazis in personal super-tanks, spawned a zillion types of crap, from a plastic zip-up playsuit to remote control wheelie Daleks to Dalek Sky-Ray ice lollies. (An ice lolly is like an ice-cicle.) Embarrassingly, a shitload of toy Daleks actually appear in longshot in the story Planet of the Daleks, as an army of super Daleks preparing to conquer the galaxy.
Design breakthrough: Doctor Who pioneered the art of filming in front of a greenscreen — but didn't exactly perfect it. More successful were John Friedlander's latex masks (Davros, the Ogrons, the Draconians) and Delia Derbyshire's pioneering all-electronic arrangement of the theme music.
Life lesson: It's not murder if you trick the bad guys into blowing themselves up (in, like, every episode.)
