Disney+ is an American subscription video on-demand over-the-top streaming service owned and operated by the Media and Entertainment Distribution division of The Walt Disney Company. The service primarily distributes films and television series produced by The Walt Disney Studios and Walt Disney Television, with dedicated content hubs for the brands Disney, Pixar, Marvel, Star Wars, and National Geographic, as well as Star in some regions. Original films and television series are also distributed on Disney+. Disney+ relies on technology developed by Disney Streaming Services, which was originally established as BAMTech in 2015 when it was spun off from MLB Advanced Media. Disney increased its ownership share of BAMTech to a controlling stake in 2017, and subsequently transferred ownership to DTCI, as part of a corporate restructuring in anticipation of Disney's acquisition of 21st Century Fox.
