NEW YORK (AP) — Used to be that CEOs were hired for their knowledge of the industry, years of experience and the ability to lead with a tight fist. But the role of the top job has changed dramatically over the last several years.

CEOs increasingly are being pressured to cut costs, while growing their business. They’re being prodded by investors to push for global expansion, while being asked by customers to be more socially responsible. And at a time when having strategies for social media and data security are becoming integral to doing business, CEOs are expected to keep up with the frantic pace of technology.
