Ken Jennings and Brad Rutter, two of the most successful players on Jeopardy, played on the quiz show against IBM's computer in the second match of the game. Jennings' final answer of "Bram Stoker" also had a handwritten note, saying "I for one welcome our new computer overlords".

The two-day totals highlighted the extent of the victory for Watson, which uses question-answering technology. IBM's Watson had $77,147 (£47,842) at the end of two days; Jennings had $24,000; and Rutter finished with $21,600.
