From USA Today – October 30, 2012

The fandoms first real controversy began with the prequels (if you exclude the “Han Shot First” deal). However, this isn’t about my opinion of the prequels (I love them, btw). This is about what happened 10 years ago, when George Lucas decided he was finished making Star Wars movies and sold the rights of the franchise over to Disney. One of Disney’s first acts was the “decanonization” of anything written after Return of the Jedi (also known as the Extended Universe, or EU for short). Thus begins the Star Wars Canon vs Legends discussion.
