That fight might be starting now. The advertisers couldn't help but notice during the conventions that a cable station outdrew all of them, despite obviously being in far fewer houses. Advertising dollars could be impacted here. Further, it dawns on the majors now that they all have a shrinking audience, but they are too stubborn to be balanced. The solution is to try to weed out a weaker network, which happens to be CBS at the moment.
I just love to see them cut each other up.
Better they fight and plot against each other than against us.
