"After many years with the studio, Todd Hollenshead decided to leave id Software to pursue other personal interests," Bethesda's Pete Hines said. "While Todd was not part of the development teams, he was an integral part of id Software's success as the business head of the studio and we wish him the very best in his future endeavors."
Hollenshead joined id in 1996 as CEO, then served as the company's president following id's acquisition by ZeniMax in 2009. Hollenshead additionally hosted the annual QuakeCon gaming convention.
Development of id Software's current project Doom 4 has been reportedly troubled, as anonymous sources alleged that the game suffered at least one complete reboot following RAGE's mixed reception in 2011. These sources also claim that a proposed RAGE sequel was canceled in order to focus development efforts on Doom 4.
