In an ideal free enterprise world, that's the way it would work. But CBS (or whatever its corporate parent is now - Westinghouse?) been ruled for years by the maxim of "we control the message and we won't put out anything out there to the public before it's reviewed to make sure its in accordance with our political agenda." That's just their corporate culture - regardless whether it's electronic media or billboards or whatever. What I'm saying is that this is a deviation from the "usual." It either means that the "usual" is changing with the recognition that we're about to enter a new era in Washington, or that some heads will soon roll in their executive offices.
I kewft the ad biz in 1992 -- when CBS Outdoor used to be 3M/National. At that time, no outdoor plant would've adapted a management attitude such as you describe.
In twenty years, I'll grant that could've changed. But it's hard to imagine serious businesses being managed in such a fashion (TV networks have never been "serious businesses")
