Sixties Doctor Who had established women generally into a subordinate role. Typically, female characters would be required to do little more than look pretty, ask questions, stumble over negligible hazards hurting their ankles and most importantly...scream!
An attempt to introduce a less conventional companion had been made at the beginning of Patrick Troughton's final season, ultimately however, the initiative was lost, and the promising Zoe Herriot rapidly became eye candy, donning ever shorter and more figure hugging costumes.
A new female renaissance finally arrived in 1973 in the shape of Sarah-Jane Smith. Sarah was stronger and far more independent than many of her predecessors, traits which proved popular with the audience and become a precedent for future companions.
But this revitalization wasn't merely confined to the Doctor's travelling companions. Women enjoying more robust roles would become a regular feature of Tom's era, including many villains, a role traditionally fulfilled by men.
