The Star Wars expanded universe (SWEU) encompasses all of the officially licensed, fictional material of the Star Wars saga, outside of the feature films, The Clone Wars film and series, and Rebels series produced by Lucasfilm. The expanded universe includes books, comic books, video games, toys and other assorted media.
On April 25, 2014, following the acquisition of Lucasfilm by The Walt Disney Company in November 2012, it was announced that all previously released expanded universe content would be rebranded as Star Wars Legends. A new company division, Lucasfilm Story Group, would ensure from now on that all new comics, books, games and other media are non-contradictory to each other and previous works, and valid to the story being told in the films. Given they are part of a similar story, however, content and characters based on Legends works may appear in the new "storytelling approach". More: en.wikipedia.org.
