PBS or NPR are the only sources I trust, but even then I take all of the news with a grain of salt.
Every news media outlet is going to operate in the interest of some one. The major networks are, as mostly everyone knows, owned by huge corporations.
So publicly funded news is what I turn to, keeping in mind that they still have to appeal to a large an audience as possible, so they are still obligated to pull their journalistic punches, just less so than outlets owned by Columbia, G.E., Disney, etc.
