I thought we had this discussion already. Sycamore is correct: It is biased to whatever pushes people's buttons and that includes anger. Also, if you lean to the right, you are a lot less likely to remember something that is reported to anger those that lean left but you will never forget the small comment made on the news that gets the right upset.
I don't think the news is "owned by" the left, right, or anything like that. It is biased, but it biased specifically to sell.
...unless its Fox News, that is.
