I don't think this situation has changed in essence. Media outlets may now filter first on party affiliation, but they haven't replaced their dependence on official sources with better independent investigative reporting, for instance.

Or glowing, fawning reverence. It depends on the media outlet and the official (really the official's party) in question. The screw turned for Cuomo, but I imagine for every Cuomo, there are more darlings that go unchallenged.
His hypothesis is that what was once an information trickle has become a virtual tsunami with the internet + cell phones + satellite television, etc. Governments have no control over the flow of information, which they had at least a semblance of pre-2000. This wave of information has not only exposed the worst excesses of the elites, but has also exposed the enormous gap between their authoritative promises and the actual results they produce.
This has pissed off a lot of very entitled people, who don't take the fact that the gap has always existed into consideration, who for historical reasons place very high expectations on government, and as a result attribute bad intentions to the previously mentioned poor results.
Not only is the media courting those people, they are made up of those people. So you get a media that just heaps negation on even the smallest failure of government. It's not just for clicks -- they are true believers in that they think they're doing the right thing.
