American news sources tend to cover the United States mainly. The BBC offers a larger area of coverage, although it tends to be liberal. Plus, their website is tidily arranged, whilst many American news websites are a riot of color and haphazardly arranged.
I had to live outside the US for a few years to realize how inwardly directed our news is. American ignorance of what's going on in the rest of the world is a fertile ground for the jingoism that makes for the Ugly American impression both at home and when traveling.
