^^ Among the reasons I'm looking forward to the next volumes dealing with Seasons 2 & 3. We might learn some details we're presently unaware of.
It's no secret NBC was getting fed-up with GR even during the first season. Maybe if GR had been smarter and realized NBC weren't the bad guys he was making them out to be they would have cut him and the show more slack. As was mentioned in the book decisions aren't always based on sound business---there's often a lot of personality and personal agendas and bias involved, things that can blind someone from making more rational choices.
