Attendees gather at an IBM Watson event in lower Manhattan, New York January 9, 2014. IBM said it will invest more than $1 billion to establish a new business unit for Watson, as the tech giant hopes to get more revenue from the supercomputer system that beat humans on the television quiz show “Jeopardy”. The world’s largest technology service provider said the IBM Watson Group will be headed by Michael Rhodin, who was previously senior vice president of IBM’s software solutions group.
