Why it matters: My prediction last week that James Holzhauer would win the "Jeopardy!" Greatest of All Time tournament didn't come true last night, as Ken Jennings took the title in dramatic fashion. The match was up for grabs going into Final Jeopardy, which was about Shakespearean tragedies, and Ken shocked me by betting zero (although he didn't shock me by getting the right answer of "Who is Iago?" -- his wide range of knowledge throughout the game was incredible). James bet everything, as he tends to do, but he guessed wrong -- "Who is Horatio?" -- so he and third competitor Brad Rutter went home with $250,000 each, while Ken got $1 million. All in all, I think the tournament was great television -- and it wound up being a great tribute to host Alex Trebek as well. -- Cathy
