A question for all FOX NEWS viewers?

Is fox news itself fair & balanced, or is it a counter-weight to the main stream media? Because I think they can't be both. They have used the counter-weight argument before(which suggests they're on the right to balance everything out), but have also used the fact that they have left wing & right wing pundits during their on air debate segments(which suggests they are themselves fair & balanced. But they can't both be directly in the center and be a counter-weight, can they?
