Fox recently started a national 24-hour feed for Hulu Live TV subscribers that live in 70+ markets where Fox does not have an agreement in place with the local broadcast station.

Negotiating leverage — The viewer is not missing out on Fox broadcast content (primetime shows, etc.).
NBC Chairman Bob Wright floated a similar idea in early 2000’s.
