BBC news is one example (corporate alternatives? Telegraph/Daily mail). In the US, the only good national source of news on television is the News Hour on PBS. Frontline, as dramatic as it is, is much more palatable and thorough than its corporate investigative-journalist counterparts. Similarly, Public radio stands alone as a good source of news and commentary.
Many European countries have followed the model of the BBC, with very good results. Holland (where I'm living) has an interesting model where public broadcasting organizations make tv/radio programs, and those organizations are allocated money and airtime by the government based on their membership/viewer numbers.
Just because there are conflict-of-interest problems with public (government) money funding the press doesn't mean that there aren't equally serious conflict-of-interest problems between private (commercial) money doing the same.
