Bruce Nelson, Omnicom's Vice Chairman, gave his historical perspective of the evolution of 20th/21st-century media at AO's OnMedia conference last week. He had some interesting things to say about metrics - if you measure hits, you'll end up with a lot of fraternity humor. As lead and sales tracking improves, maybe the quality of online content will too. The whole panel is available here: http://alwayson.goingon.com/page/display/23247?param=session/189
