I just watched the News Hour, and there was a panel discussion including a historian, Professor Diane Kunz. The panel was asked what’s different about this war from previous wars, and Prof. Kunz’s reply was that this is the first “worldwide web war” — I’m paraphrasing here: that people are getting information from so many online sources outside of the mainstream media coverage, including blogs and other news sources from all over the world. This is different from previous wars in that the government is going to have a much harder time controlling what kind of information people receive.
There is video of the News Hour online, but today’s episode isn’t posted yet. Presumably when it is, it’ll be available via this page.
