In the advent of launching both the GameCube and Game Boy Advance, Nintendo sought to change the structure of its corporate management. In June 2000, in an attempt to include both software and hardware experts in the board of directors, EAD and Integrated Research & Development general managers, Shigeru Miyamoto and Genyo Takeda respectively, entered the body. In addition, former HAL Laboratory president and future Nintendo president, Satoru Iwata, also entered the board. With Miyamoto being promoted to the board of directors, he was now in charge of overseeing all of Nintendo's software development. To fill Miyamoto's void as a producer, there were a series of promotions in the division: starting with long-time Miyamoto colleague Takashi Tezuka, as deputy general manager, as well as promoting several senior directors like Eiji Aonuma, Hideki Konno, Takao Shimizu, Tadashi Sugiyama and Katsuya Eguchi to producers overseeing their own development teams in the division. Nevertheless, after the promotion, Miyamoto still went on to produce some games.
