SAN FRANCISCO (AP) IBM says former Weather Co. CEO David Kenny will be the new boss for Watson, the Jeopardy-winning "cognitive computing" service that's a central element of CEO Virginia Rometty's campaign to find new revenue for the struggling tech giant.

Watson is a computing system that uses machine-learning and natural-language skills to analyze and find trends in data from a wide variety of sources. IBM has been promoting the service as a powerful tool for use in health care, retailing and other industries.

IBM announced last year that it was buying The Weather Co., including its websites, apps and data platform, for an undisclosed sum. The cable-TV Weather Channel was not part of the deal and continues to operate independently.
