A question for the media "all-knowings"

What would the best avenue to systemically change news coverage of minorities?
Agreeing with the article we just read in class, how could the environment of the newsroom change in order to represent the surrounding news. Like most editors I keep a very watchful eye on what is and is not news. More than not, my personal lenses are race and gender blind, but I still feel them inaccurate.
How can this be avoided?
First, the cultural spectrum in the newsroom most be of a broad nature: men and women from divergent and expansive backgrounds. Second, I believe a "beat" that specifies woman and minorities would also be beneficial. Third, a pristinely clear understanding of the audience of the paper.

Experimental ideas
An opinion of mine is that mass-media, on all levels is slowly stepping backwards. The national papers will slowly lose traction to the local, or market specific ones. This, hopefully, will again ignite excitement into informational products, be it paper or screen based. The audiences seem to hunger for what is close to their small world. 24 hour cable cannot compete with that kin of logistic.
