Just to be fair - some comments from FOX etc.

Although, I must say that most US media I see is biased at some point. E.g for the last 2 years most US media has run every scandal/hint of how terrible China is, and how they are cheating in production etc. There is no time left for how the US itself undermines global trade by high tarifs and sabotaging negotiations on agricultural products etc.
Most national media poke at foreign leaders, nations, traditions, corporations etc. That is true about german, french, english, US, japanese, chinese, brazilian, spanish, russian, italian ... whatever ... they all distort news, twist connotations to favour themselves and vilify others.
Well, it's a fairly well-known fact that USA is good at analysis - but not analysis about themselves - lacking in reflection, or maybe empathy. Europe is a little better than the US on reflecting over their own actions and seeing their place globally, although they fend for their own national goals individually. The US media seems more about how to keep the dominating role. The Israeli media is pretty varied, with extremes going in many directions. The japanese seems like they distance themselves, while trying to excel or keep pride of what they have greatest potential. In Brazil the media is flipping between mad outrage, chaos and corrupt cronies. One honest try on objectivity and being critical towards corruption is BAND-news, though. The rest of brazilian media is swamped with reports on violence, crime and outrage - or completely opposite with dancing hot women, stupidifying soaps and shows - kind of like italian TV.
Reporters and presenters limit questions and guests to views and voices that they want to present, often "friendly opinions" enjoying a repeated shared limelight - many times without any value at all. It happens on Larry King to whatever other live presenter/anchor and correspondents.
In all the really big countries, it seems that well founded deep journalistic insight gets drowned in all that happens and is reported from around all the corners of the country. Only a minute part of the population seem to have some well informed opinion, and many times it seems opinions is just regurgitated party policies or something they have heard elsewhere, without any shred of critical thinking. In the end - I guess that is something that most share, regardless of whether one lives in a large or small country.
It seems the media-savvy in the US have come much longer in being able to manipulate and shape public opinions to build political support than in the more (naïvely?) moderate countries. The interdisciplinary field of systems theory and sociology can probably explain more - and give useful models for how the media influences perceptions and "power/support".
