Don't forget internet sources such as Free Republic. Also other good news is that the ratings for the news programs on the big networks are declining rapidly. There will be a time in the near future that it will be pointless for networks such as CBS to have evening news with Dan Rather. Unless they will be satisifed with much smaller audience.
The only reason that they got away with that act for so long is that there were no other alternatives. Today, it's a whole new world. Heck, I would not be the way that I am if it was not for the internet. Perhaps I would just be more interested in sports.
FR is a great example of the internets ability to reach people who have minds of their own and can think for themselves. Unfortunately most americans are programed to process the 10 second liberal news media sound bite as reality.
The big three major networks still have a rather large audience, but fortunately it is declining.
