no- I like to sort through all of it and make my own decisions. There's so much diversity between Fox and MSNBC those two could only "control" if you just listened to one or the other. I listen to both, and they sorta cancel each other out (although I find Fox to be far more persistent- and there's annoying fact that they actually use the word News" as part of their name!) It's hard to not be "influenced" by all of them, although I feel that some of the influence is the opposite of what the talking heads intend. Case in point- I almost always am amazed at the obvious agenda of Hannity, and almost always end up on the opposite side of his rants.
BBC and NPR are far more reliable sources of actual news, and CSPAN goes completely unfiltered, which is cool but tedious. At least there is no over the top "reporting bias" there.
