These supplements to the film trilogies comprise the Star Wars Expanded Universe, and have resulted in significant development of the series' fictional universe. These media kept the franchise going in the interim between the film trilogies. In 2008, Star Wars: The Clone Wars was released to theaters as the first ever worldwide theatrical Star Wars film outside of the main trilogies. It was the franchise's first animated film, and was intended as an introduction to the Expanded Universe series of the same name, a 3D CGI animated series based on a previous 2D animated series of a similar name.
