see here is the fallacy. the vast majority of people have 1 or maybe 2 providers where they live. if it is 2 it's usually dsl vs cable. so in all practivle terms for maybe 90% of America only 1 isp serves any given location. yes there are more than 1 providers across the land. and more to the point, the map provided by Time warner/comcast showed they only overlapped service by a very small percentage.
