A key aspect of an offensive military operation is to "get inside your opponent's decision cycle," IOW to move faster than he can make decisions to react to your changes. That is what the internet has done to TV and print news. Why should I wait until tonight's broadcast or tomorrow's paper when I can have the news at the speed of posting? The New Media has effectively gotten inside the MSM's decision cycle, and the MSM has no clue how to handle it.
Great, isn't it?
