The Technologist Effect.
I was thinking about the Conan O'Brien situation. Coco likely had a younger and more technically sophisticated audience than JayLo. A high percentage of this savvy audience may well have been recording Coco's show to watch later, rather than watching live. This behavior would have a very high influence on the 'follower effect' that so many affiliates were complaining about.
Also, Conan's last shows were some of the funniest I seen in any time slot recently. I can't wait to see what Conan and his crew do next.
