Jon Iwata has been a Power List staple not only due to his title, but also his strategic vision that has earned him the CEO's ear. He leads a global team responsible for communications, corporate affairs, and product and services marketing. He is also vice chairman of the IBM International Foundation.
IBM marked its 100th birthday this year by hitting the $100 billion revenue mark, but also setting in motion a succession plan for Sam Palmisano, who has been CEO since 2002. Until last year, Iwata reported directly to Palmisano. Now he reports up through Virginia Rometty who was promoted to SVP and group executive of sales, marketing, and strategy. Rometty is rumored to be the frontrunner as Palmisano's successor.
