A Short Film by Adam Curtis: "The Rise and Fall of the TV Journalist" - a four minute blast of dark LULZ and McLuhan brainfood.
For a much more serious & in-depth treatment of a worthy subject, though: "The Death of Investigative Journalism" is long but packed with insights and facts only an old insider would know. (Apophenia conspiracy theory essays based on publicly available information, of course, have nothing to do with journalism....juuuuuust to be clear.) On that note, here's Jaron Lanier discussing why the corporatization of the internet was inevitable by design -- sharp commentary and he may even be right. Well, right-ish.
