If you've read The Assault on Reason, you're familiar with Al Gore's case that TV changes how we think and conduct public debate. There's a new MySpace group dedicated to the effects of mass media at http://groups.myspace.com/innerindependencerediscovery
I haven't been able to find any other public groups on the internet interested in how mass media change us. I you know of any, please leave me a reply. Or send me an email ruthanthonygardner@yahoo.com I look foreward to meeting you in the MySpace group Refuse Mass Media Poison, Sleeping Pill of Independence.
