When Apple announced that it was bringing movies and TV shows purchased in the iTunes Store to iCloud, every major production house was onboard except Universal and Fox. Due to licensing conflicts with HBO, Universal and Fox were not able to offer video content in iCloud initially. HBO later said that it would be loosening its grip on the studios to allow for licensing agreements with Apple.
It now appears that Universal Studios has been able to start offering its movies in the iTunes Store for re-download in iCloud.
