Cosmos? On FOX?!?

Just wondering how this is going to work-

Narrator: “There are those who believe the Universe started with the Big Bang nearly 14 billion years ago. Those people refer to themselves as cosmologists- we usually refer to them as heathens, heretics, and blasphemers.”

And what about the audience expecting Family Guy and American Dad in that time slot?

And wondering if it will last the entire 13 weeks?
