That CEO is a total businessman and only cares about the ratings that bring in advertising revenue.
If there were any other significant sources of revenue for a network, he'd probably care about those, too. But as of now, the new revenue streams like ad-supported or paid downloads, are too trivial a part of the mix for him to take notice of. He's just doing his job, and any other network head would say the same thing he did.
It is true, however, that CBS is in such a safe and secure place that experimenting with Star Trek is less attractive than it might be, say, for NBC. But NBC being in dire straights might make it less likely to experiment either - can't take the risk.
CBS is not the home for Star Trek with him as CEO as others have said many times.
It shouldn't air
on CBS. That doesn't mean it can't be a good business proposition for CBS to make, and license to air elsewhere, where it's a better fit. But it doesn't sound like Moonvies is interested in either.
