SlimFatBoy, yes, Baudrillard did propose that theory - he often wrote about the power of the media and propaganda. I would have to re-read his Gulf War analysis to make any sort of intelligent response to it.
I became interested in Baudrillard when I was studying the politics of representation and how that is played out in the media through the use of propaganda. This was at the time that the WWW was being born and theoretical discussions about how it would impact culture and the political world was common. Speculation about how cyberspace was 'the new frontier' and about how terrorism would be fought in cyberspace for the control of information and power fit well into Baudrillardian theories.
I find Baudrillard's writings to be dense and difficult to untangle - which could be a language barrier problem - but, I keep reading his work. Every once in while, I get an eureka moment from re-reading things that didn't make sense previously. Especially when I read things from years back that now have real application. I call Baudrillard 'the prophet' of the technological age.
Using Barthes to analyze JW meetings sounds like a fun exercise. My interest in Barthes is photographically based. "Camera Lucida - Reflections on Photography" is seminal reading for photographic enthusiasts. But, I also like the way that he writes about myth and how it is constructed and maintained in popular culture. Good stuff.
