The show had to be sold to advertisers and similarly had to sell to the television audiences of the late 60s. Did Star Trek want to do more? Yes. But the show was in a constant battle just to stay on the air.
Roddenberry was told to get rid of Number One, but that didn't stop her character from still making it to millions of television screens. And in a lot of ways the women were allowed to show more than just short skirts while not threatening the male power structure of the networks.
Best Example is Uhura.
While the part of communications officer may have been played off as a space age receptionist in some people's eyes, the job itself is actually a highly technical one.
Further, Uhura also shows significant mechanical skills, as when she is attempting a repair in Who Mourns for Adonais? (or when she locked Kirk out of communication in This Side of Paradise), Spock says that he can think of no one better suited for the job than her.
Does her character's aptitude end with communications tasks and equipment? No.
On a number of occasions Uhura has manned the navigation station (The Man Trap, The Naked Time and Court Martial for examples), showing that she has had extensive experience at that position, and may have held the position of navigator before moving to communications. She has also manned the library computer station (The Man Trap) showing that she has a background there as well. And when she has to be retrained in The Changeling, Chapel comments on the fact that she shows an aptitude for mathematics (countering the belief at the time that women were poor at mathematics).
And that is just what I can think of off hand.
Star Trek of the 60s had to play the hand it was dealt, but that didn't stop them from rebelling against what the network and advertisers were trying to get them to conform to. And in the end, maybe that was more than the audience of the 60s could handle.
But what attempts were made obviously counter a purely sexist or chauvinist bent on the part of the producers.
Well put. You and Plum could both write dissertations on Trek and Feminism. Both of you make very valid points.
