Do something with the nights?
Yeah. Fox News Channel just loops the early evening programming throughout the night.
Instead, I think, they should have more shows on. Maybe more Red Eye type material, or even live news. Just no more loops of O'Reilly, Greta, and H&C.
Maybe a max repeat of those once a night and make them available online (without DRM would be nice, but I'm dreaming), but do something with the night hours.
As for Fox broadcast, I don't think they would ever produce a 30/60 minute news program. It would be nice, but.. I just don't see it.
