The Expanded Adventures is the term used to encompass all officially licensed Indiana Jones spin-off material beyond the theatrical movies such as the television series, novels, comics and video games.
A variation of the term "Expanded Universe" (which was formerly used for material beyond the core, episodic movies of George Lucas' Star Wars franchise), it was coined for Indiana Jones by Lucasfilm Ltd.'s Indycron continuity database administrator Leland Chee on his blog dated September 10, 2007.
On April 25, 2014, it was announced that the Star Wars Expanded Universe was no longer canonical and would instead be rebranded as Star Wars Legends to allow The Walt Disney Company – which acquired Lucasfilm in 2012 – greater freedom to explore new storylines without conflicts. Whether or not a similar restructuring will, or has already taken place, with the Indiana Jones Expanded Adventures has yet to be specified.
However, Jock Lindsey's Hangar Bar opened in 2015 with references to earlier Expanded Adventure works, indicating that some material, at least in part, have been retained in continuity.
