Tim Cook was an innovator — just not the Jobs kind

Apple's value eclipsed a couple of Saudi state-owned oil companies under Tim Cook's direction. Cook joined Apple in 1998 and expanded its relationship with Foxconn, making huge investments that paid off for both companies. Apple managed unheard-of profit margins on the iPhone, and Foxconn became a trillion-dollar industry leader. Cook optimized Apple's product lines and supply chains, turning the company into a revenue-generating machine with record-breaking sales.
