True, but all you have to do is look at the types of stories they put on display and then read the editorials. Papers have always had a "left or right lean".
Many local outlets are owned by conglomerates when you follow the money too....
This is the value I still see in the mass media.
As long as I know the bias of the show I'm watching, I can just read between the lines and compare it to other shows that have a differing bias in order to get a more complete picture of events.
If you couple that with an exploration of alernative media, you can learn a lot, both about media bias, which clearly exists, and what's really going on, which is rarely reported on.
