A lot of the problem with the media is that reader's don't seem to care. I have seen news articles about this issue, but if people aren't interested in reading them the media outlets are not going to put a lot of effort into continuing to follow the issue - and with online media outlets the norm they get very clear feedback about the issues that actually interest people.

People don't seem to care much about issues which don't directly effect them and unless a story is novel and entertaining they don't want to keep following it. If people in general put even a fraction of the time and energy into social justice issues as they do into things like following true crime stories, reality tv or Taylor Swift concerts the world would be a very different place.
