Apple’s argue with HBO has come to an end. Few months ago, Apple finished the debates with HBO who agreed to make Universal Pictures content available for download. Fox went live this Thursday and joined the other movie studios on iCloud.
Thus, iCloud users can now download content from Lions Gate Entertainment, Sony Pictures, Walt Disney, Paramount Pictures, Time Warner’s Warner Bros, Universal Pictures and 20th Century Fox.

Back in March, movie catalogs from both Universal Pictures and Fox were accessible, but only Universal movies were available for download. Several iCloud users noticed last night that the warning marking movies from Fox had disappeared, meaning that Fox Studios finished negotiations with HBO and got loosened of its constraints.

Meanwhile, other two major companies, namely Universal Pictures and Twentieth Century Fox, are unable to integrate their movies with Apple’s iCloud due to their deal HBO, Time Warner’s TV channel, and to HBO’s exclusive rights.
