Fox has plenty of reporters. But they are all out in the field. The people that Fox puts on screen are not reporters.
Some of your ideas are pretty good. But maximizing cable still limits the amount of facts that get out
Broadcast is (should be) our next step.
The only one I can think of who I believe is a good news reporter at the station is Patty Brown. She's earned her place there as a reporter. You're right the rest are in the field and it's a waste because they get so little coverage time.
