Zynga has shuffled its deck in a management reorganization and tossed out its chief operating officer, John Schappert. The move came Wednesday after a turbulent two weeks in which Zynga saw its stock fall to record lows after a disappointing second-quarter financial report and was smacked with two lawsuits. "John has made significant contributions to the games industry throughout his career, and we appreciate all that he has done for Zynga," Mark Pincus, Zynga's chief executive, said in a statement. "John leaves as a friend of the company and we wish him all the best." Hired just 16 months ago, Schappert arguably was Zynga's highest-profile recruit from the world of traditional video games. To woo him away from his previous post as chief operating officer for Electronic Arts, Zynga awarded Schappert a compensation package worth close to $53 million over three years.
