Up to now Lucasfilm Ltd. has been a private company wholly owned by its chairman and founder, George Lucas. What did Disney buy for all that stock and cash?
Lucasfilm -- George Lucas's production house, home to the Star Wars film franchise as well as the persistent Indiana Jones series, still-viable properties like The Land Before Time and Willow, and durable back-catalog items like Labyrinth.
Lucasfilm Animation -- Home to Star Wars: The Clone Wars, starting with the feature film and continuing with the ongoing television series.
Lucasfilm Animation Singapore -- Produces digital animated content for film and television, including in-house projects like Star Wars: The Clone Wars, as well as visual effects for feature films and multi-platform games.
Industrial Light & Magic -- Innovators in CGI and other forms of digital postproduction, with the largest motion-picture industry workforce of visual effects digital artists.
LucasArts -- A major developer and publisher of interactive entertainment software worldwide, including lines of popular games based on Lucasfilm properties like Star Wars and Indiana Jones. Disney might also choose to revive LucasArts's interest in non-Lucas game franchises (it was once famous for games like the Monkey Island series).
Lucas Books -- Publishers of a broad range of fiction pertaining to Star Wars and other Lucas properties.
Skywalker Sound -- Industry-leading audio postproduction, sound design, and music recording.
Lucas Licensing -- Manages the global merchandising activities for Lucasfilm's entertainment properties.
Lucas Online -- Creates Internet-based content for Lucasfilm's entertainment properties and businesses.
Star Tours -- The theme park arm, which already has had a property link to Disney operations at Disney theme parks in Anaheim, Orlando, Paris and Tokyo, and therefore kind of the preexisting germ of the Disney-Lucasfilm relationship.
The only major Lucas endeavor not now owned by Disney (Lucas was a participant in the development of Pixar, which is also at Disney now) is the theater sound system THX, which, despite being named after Lucas's earliest sci-fi film project, has been a separate company since 2001.
All of these divisions, especially industry colossi ILM and Skywalker Sound, are lucrative even as they stand. And there's no question that Disney plans to invigorate all of these platforms and synergize them as much as possible with existing Disney interests.
