I referenced Why Broadcast Journalism is Unnecessary and Illegitimate in that thread. That was the best I could then do - but I think that this thread is beginning to approach the definitive answer to the characteristics of journalism and why not only broadcasting but all of journalism is vulnerable to a lawsuit. It turns out that the Associated Press was found to be in violation of the Sherman Antitrust Act back in 1945 . . . and that an amazing amount of the objectionable qualities we observe in journalism can be laid at the door of the AP.
