From when I tsarted many many years ago women are far recognized far more for on air talents.  It used to be women were in found only in the traffic department and promotions.  A few slowly made into news.

Currently women hold an equal if not higher percentage of on-air positions.  I have no problem with it so long as the individuals are good broadcasters.  I also believe consultants decided that after the morning show is over the target audience is women working in offices and Dr, Dental offices etc.  

The consultants most likely said women are more likely to listen to another woman over a male.  I disagree.  I believe people listen for a mix of personality and the correct music for the desired age group.   A male personality has just as much sway with female listeners if he is sensible enough to talk about topics females will find interesting.  Bottom line, relate to the audience and play the music they enjoy and most of all ensure it's not nerve shattering.  What I have heard in several occasions is on-air talent, male and female, coming across too swarmy and that just irritates the hell outa me.  

No there are not many as the "star" in AM drive.  Erin Davis comes to mind as one.  I think it's just a question of time before there are more.

Basically we agree on the other apsects.
