HBO and Fox have renewed a rights agreement originally set to expire in 2015, AllThingsD reports. Under the new deal, Fox movies will continue appearing on HBO until 2022. More importantly, however, Fox and HBO officials say that the agreement includes a "softening" of something known as the electronic sell-through window. Previously HBO maintained a strict policy that while it was running a movie for the first time, no one else could sell or rent a title electronically.
