Publications, Inc., which was a subsidiary of The Walt Disney Company that published "Disney Comics" during that time span.  W. D. Publications, Inc. created Disney Comics in 1990 so that The Walt Disney Company would not have to rely on outside publishers such as Gladstone Publishing.  In the USA, Disney only licensed their comic books to other publishers prior to 1990.  Since the demise of the Disney Comics line, Disney has licensed out their properties to various US comics publishers, while continuing to publish comics in the since-defunct magazines "Disney Adventures" and "Disney Adventures Comic Zone", as well as numerous book projects, and has reentered the periodical comics market through their 2009 purchase of Marvel Entertainment.  Marvel and Disney Publishing began jointly publishing "Disney/Pixar Presents" magazine in May 2011 but did not revive the Disney Comics imprint as Boom!  Studios would continue to publish classic Disney character comics.
