Watson, named after IBM’s founder, Thomas J. Watson, is an artificial intelligence program developed to answer questions posed in natural language. Watson competed on the TV game show ‘Jeopardy!’ in 2011, defeating past champions Ken Jennings and Brad Rutter. During the game, Watson had access to 200 million pages of content, including the full text of Wikipedia. Watson consistently outperformed its human opponents on the game’s signaling device, but had trouble responding to a few categories, notably those having short clues containing only a few words.

The original Watson was made up of a cluster of 2880 POWER7 processor cores and 16 Terabytes of RAM. IBM’s master inventor and senior consultant Tony Pearson estimated Watson’s hardware cost about $3 million and with 80 TeraFLOPs would be placed 94th on the Top 500 Supercomputers list in 2011. In 2013, IBM announced that Watson software system’s first commercial application would be for utilization management decisions in lung cancer treatment at Sloan–Kettering in conjunction with health insurance company WellPoint. Watson’s business chief Manoj Saxena says that 90% of nurses in the field who use Watson now follow its guidance.
