It's not that "the media" has gotten worse at their jobs. Rather, there simply a lot less funding for reporters. The hit in funding has become much worse in local reporting -- especially local newspapers. However, if this is viewed as a training ground for the few large national/international news organizations, it's easy to see how this has a profound impact for even the large and well funded publications.
There's simply much less reporting happening than their used to be, and it's a real problem.
