Conflict builds ratings. Ratings build advertising. Advertising generates revenue. Therefore, the media like to stir up conflict and this can undermine democracy.
That was the rationale from one CNN pundit commenting on Obama's administration.
Substitute "Argument" or "Debate" for "Conflict" and I see that whole chain of relationships as a positive thing for democracy and for the media, made all the more appealing when everyone has a stake, can contribute opinions and vote for the outcome of their choosing. The very interactiveness of Interactive Democracy may help the media build a bigger business and they may dig up every disparate point of view to make the debate more interesting, informative and democratic.
