The combined audience for network news is 12-15 million. This is the largest group by far. My guess is that the Daily Show is second. I don't see that on the list.
I guess people don't want to admit that they watch network news. Only 1 percent claimed to get their news from each of the major networks. Or, maybe the network news watchers are the takers who can't afford cable nor a land line. Why bother when you have a free Obama Phone and all the politically slanted news you can watch for free?
