News media has always been heavily biased one way or another. There's nothing wrong with this. The problem comes with the source of the bias. It used to be small news outlets trying to stick it to the community's most apparent "bad guys" like big business or the government. They were small and independent. However now, the largest and most influential companies in the world are the owners of the mainstream news media. Disney or Murdoch or it doesn't matter, most people know by now that the companies funding mainstream media are doing it for profit only, and have only that interest in mind. If you see something seemingly controversial on the news it's only because that organization feels everyone agrees (or at least, everyone they think watches their show.)
However, I find it worrying that people trust google. They are just as rabidly chomping at the bit of profit as Disney or NBC, or whatever. They don't have an altruistic plank in their yachts. They pretend to "not be evil" but regularly exert their dominance in public exposure via the web to piss all over other markets in an effort to clear a path for their own business strategy. They make things "free" so nobody can compete in conventional terms, forcing them into advertising revenue or similar structures and guess who has a huge monopoly on advertising online? Yeah... so before you go suckling the teet of google or similar companies, remember what it is they are after in the end.
That said, it's still more understandable to view a source like google as more trustworthy, but the problem is that google does not report on the news, they only repeat it from the other, less trusted sources, so it's sort of pointless to compare them.
When it comes to trusting information, it is acceptable to think the official source will be more truthful, even if occasionally they are not. News media gets a pass for some reason, maybe citing bad information, but authoritative organizations get panned for any lies, even accidental unimportant ones. So when an organization like MS or Apple or Google lies about something, it's either well known right away or it's well hidden, and the latter is much more common in my experience.
Not trusting social networking sites ... well that's just a surprisingly, unusually rational position to hold by the general public. Personally I "trust" twitter itself more than facebook, but trust the information less. I trust facebook to constantly try to screw me the way I described google doing it, subversively, for their own profit, under the guise of helping. Just see the constant quiet changes made to their privacy policies as cases where they didn't get away with it. Twitter is easier to trust just because they don't promise anything. You can protect your tweets, but that's about it. You can block followers but you know your tweets and most info is public. Twitter hasn't changed these policies, there is barely anything to change anyway. When I use twitter, I feel it's very obvious what my privacy expectations are. However, the information coming via twitter is less trustworthy than overhearing gabby women at the local mall. It's the same thing, really, except with infinitely more anonymity to hide your lies and innuendo behind.
