Also, Rachel Maddow is probably the best example on air of non-fear-based programming. She usually spends the first 10 or so minutes of her show putting the forthcoming topic in historical context, and then proceeds with a rational, calm, and thoughtful examination of the topic. This oftentimes involves verbatim reading of court transcripts for 20 minutes. The majority of her show is a fixed camera on her with a static background graphic behind her. The rest of her show proceeds with interviews of a single guest with relevant topical experience (prosecutors, congresspeople, attorneys etc.) It's what you'd expect from a Rhodes Scholar and Oxford Ph.D. I never leave her program feeling angry, only ever informed.
Contrast this with Fox News, where the last time I tuned in to that channel 3 angry people were screaming across a table at each other about how liberals are going to outlaw hamburgers. The camera is flying around like a sportscast, and there's graphics and animations blaring in the background. The people in the room seem to have no relevant credentials as to the topic at hand. Are there any environmental experts at the table? Food science experts? No, there's just "political analysts" and "strategists".
