Why does Moonves think Star Trek has to make more money than
"The Big Bang Theory" & "CSI: [Insert Some City Here]" for him to consider it?
Isn't "as much money as ...." or "a lot of money" valid enough reasons?
It's called opportunity cost. There are a limited number of hours that CBS has to show new programming. To maximize revenue, Moonves wants to fill those hours with the shows that will make the most money. If giving Star Trek an hour a week means canceling CSI: XYZ, then scheduling Star Trek results in less profit for CBS unless Star Trek can make more money than CSI.
