Jay Rosen, of the New York University Journalism School, presented this thought at BlogWorld Expo yesterday.
People used to be connected up; connected to media through their TVs. But people couldn't share with each other. In the movie Network, character Howard Beale breaks this rule by commanding, "Go to your windows and shout 'I'm mad as hell, and I'm not going to take it anymore!'"
People are still connected up, but now they can connect across, able to communicate with each other. People can create their own alternatives.
The people who used to win and dominate the vertical game, are now finding they can be undermined by the horizontal system.
