Ginni Rometty

Rometty three-peats as No. 1, even though IBM’s revenue declined for the second consecutive year, falling 5% to $99.8 billion in fiscal 2013. But her strategy of investing in new technologies is showing results (see story): In nonlegacy areas like mobile and cloud services, revenue rose 69% for each division last year. Rometty has also signed strategic partnerships, such as a deal with Apple to provide IBM’s services on the iOS platform. And in October, IBM will move its newly formed Watson business group to a new building in downtown Manhattan. Rometty has also pledged to invest $1 billion in the development and commercialization of the cognitive computing system, another future growth area for the company.
