But also, this idea that somehow now that one guy who believes San Francisco doesn't exist is "media" whereas in 1990 he's not is insane. That's a choice you've made to re-define "random crazy people" as media, the Internet didn't do that. If anything changed magically in 1995 it's how you defined what does or doesn't count as media.
Any strong, independent media ecosystem would not be so consistently sane-washing the firehose of crazy that we're being hit with every week, or kowtowing with such regularity.
Yes, you can find some obscure blog that will broadcast literally any cherrypicked viewpoint. That's not the majority of the media consumed in this country. Even when the owners of the networks differ, the message they broadcast is incredibly homogeneous.
IMHO what we're actually seeing is a huge fragmentation of the 4th estate. There is now a viewpoint on the Internet for everything, no matter how insane. That's part of what people don't like about it. This fragmentation of media has allowed airtime for MAGA views that would've been considered far outside the Overton Window just a decade ago, but that was the point of the Internet. And it's not really to the exclusion of other views, it's just that you have to go looking for the other views.
