In April 2012, the United States Department of Justice filed "United States v. Apple Inc.", naming Apple, Simon & Schuster, and four other major publishers as defendants. The suit alleged that they conspired to fix prices for e-books, and weaken Amazon.com's position in the market, in violation of antitrust law. Simon & Schuster reorganized all of their imprints under four main groups in 2012. The four groups included the Atria Publishing Group, the Scribner Publishing Group, the Simon & Schuster Publishing Group and the Gallery Publishing Group. According to CEO Carolyn Reidy, the divisions were created to align imprints that complement one another and that the structure would "lead to a sharper editorial focus for our imprints even as it takes consideration of the natural affinities among them." In 2012, Simon & Schuster launched a self-publishing arm of the company, Archway Publishing.
