Bill Mahar and Jon Stewart* are entertainers, stand-ups, much like Lewis Black, that does not mean that on occasion they veer dangerously close to the truth, but we do live in an age where pretty much comedy is the only way to do social critiques also. Of all of them I like Lewis Black the best, but he pretty much only does stand-up, so he is the least censored and scripted out of all of them.
Most of the other ones, the NBCCBSABC junk, they are even entertaining, they are just news readers, people who look good with good hair, and not much more, and what is covered on such programs has been bought and paid for not by liberals or by conservatives, but by large multi-national corporations who are only looking out for number one. And number one ain't you. You ain't even number two - as Frank Zappa wisely pointed out.
If you want real news (but you're not going to like it on many accounts, not the least of which is the truth is going to make you puke) watch Amy Goodman's Democracy Now! The War and Peace Report. She does not glam up, she is very plain looking, and doesn't care. She never raised her voice, she speaks in a monotone, which is best for what she does, which is report facts, not talking points. And she not only does stuff in depth, she's not against using 50 of her 60 minutes to tell one story, for things like health care she did that for a week, including listing off which congresspeople got how much money from which health care industry lobbyists and extensive interviews with a guy who's previous job was the head of corporate communications at CIGNA. Very interesting what he said about what the insurance companies were going to do. You can watch it - it was filmed before the debate started, and how odd, he is spot-on. She spent the last two nights doing coverage of the rise of right wing militias in the past year.
The show runs on the Pacifica System, and is broadcast on several PBS stations, but I bet where you are the only way you're going to see her in the South is on the webcasts and such.
* and to the best of my knowledge, they never deny that.
