So, not by the mainstream media, right? So in some circles they are portrayed in a bad light. I think it's an exaggeration to say they are (implied universally) portrayed as evil. My experience with regard to negative opinion against them is from people who have to interact with Union employees.
Thats really the wrong metric to look at. Yes they are the largest but the median age of their viewer base is 70 years old. They are mainstream only in a few circles but don't really represent the mainstream of America. In fact along with MSNBC/CNN(median age 65) they have declining viewership numbers. This is why all these networks are making a big push(failing) into streaming.

Fox is the single largest one, but all the other ones put together are left leaning and bigger combined than Fox. You’re just making a point about consolidation in conservative media (okay?) not about the total impact of liberal versus conservative media.
