I think that while women weren't as much of the focus during the 80's and the 90's, producers were at least making an effort to include them.

Now?

Not so much. The new Stargate series? Five men. One woman.

And that's in science fiction, y'know, the genre that's supposedly pushing the boundaries.

At least with the procedurals and things like Bones, NCIS and the like, they've got more than one woman, and the women do interact with each other.
