With respect, journalism, as a profession and as an academic discipline, has changed considerably in recent years. Because professional media providers (read: MSM) have to complete with so many amateur media providers (read: blogs, social media, thematic websites), professional media have much less power to push an agenda or to make something a story despite a lack of public interest. The media now have to be much more responsive to public tastes and interests, lest they miss a story with legs that amateur media are covering. As a result, I think it's fair to say, perhaps indisputable, that professional media (with respect to news and current events -- I'm not talking about media like cartoons and movies) have been increasingly forced to respond to public tastes rather than to attempt to shape them.
