I expect ratings for all news sources to drop

The reason is simple. There are virtually none that are actual news. Basically every source of information out there right now short of simply looking at the data yourself amounts to little more then tuning in to hear your opinion spoken by somebody else.

Everyone has moved to their corners and at this point the only actual purpose served by the so-called new sources is four people in each corner to publish their headlines and say see I told you so

I actually wouldn't even consider that a bad thing normally. I haven't regularly watch news for 30 years because I got tired of how shallow any and all stories were covered in the typical 2 to 5 minutes Snippets

It used to be that there were several print sources where you could get more in depth but even that has pretty much dried up.

Now if you really want to look into a subject you basically have to find out the sources of data and go look yourself. There are just really aren't very many legitimate sources Beyond that

So like I said it doesn't surprise me that fewer people watch the news. It might be fun to hear your own opinion spoken back at you a few times. But at some point you realize you have better things to do and that it's not very interesting
