The Symbian Foundation, the non-profit organization that develops and promotes Symbian OS, has announced the appointment of Tim Holbrow as its new executive director. He has replaced Lee Williams for this position, who resigned from the company for “personal reasons”. Lee had run the organisation since Nokia bought out other shareholders and spun it off into an open-source structure. “Williams stepped down for “personal reasons”. He has been immediately replaced with Tim Holbrow, the chief financial officer,” said a statement from Symbian. Prior to this appointment, Holbrow most recently worked as Symbian Foundation ’s chief financial officer. Symbian is continuously losing its share to new rivals like Google’s Android, Apple iPhone, and Research In Motion, as many handset makers (Samsung, Sony Ericsson) have abandoned Symbian as their mobile operating system. The platform is now supported only by Nokia, Fujitsu and Sharp.
