Yep. There have been lots of studies starting in the 1950s showing that journalism wasn't as objective as they wanted to be starting with White's study on "The Gate Keeper" and implicit bias in stories
(http://www.aejmc.org/home/wp-content/uploads/2012/09/Journal...).
The thing is, bias will always exist but you can easily get unbiased information if you simply understand how to compare and contrast multiple sources and assess them together. You also have to learn how to take your own biases into account, which is honestly one of the most difficult things to do.
I'd rather not have to do this, but you're right: If you take any 1 headline on an aggregator like Google News, and expand the related articles' headlines for the same news item beneath it, you can do some quite useful comparing and contrasting.
But then everyone immediately forgets.
