No, the comment doesn't fly. I can vouch for it at the network level from personal experience, and so can mhking. The corporate suits try to spike an average of a single story every two to three YEARS (invariably something bad about the company itself), and even then, if they succeed at all, they succeed only at their own news organization. Every other outlet will still happily carry the bad/embarrassing news. (Anyone here really think Time Warner would go out of its way to stop CNN from reporting something that makes Disney look bad? They're archrivals; Time Warner HATES Disney!)
On the other hand, the vast majority of the reporters, producers, editors, etc., are all partisan Democrats, and it affects every story they work on every single day.
There's a reason the conservative Media Research Center puts out 1500-word reports every day listing example after example of direct liberal bias, while the liberal Fairness & Accuracy in Reporting only puts out one press release every three weeks or so.
