Are you sure it was a michael moore spot? Move On was going to air the winner of its Bush in 30 Seconds contest on the Super Bowl, and also got turned down. I hadn't heard anything about Michael Moore making an ad, though.

I'm not sure I understand what kind of policy it is that says "we will only run ads for a product for sale in this time slot." Why would that be the policy? Why does CBS care if it's a consumer ad or some other kind? Anyone have any idea?
