And on the 10th night, Ken Jennings won — again.
Jennings, a 29-year-old software engineer from Salt Lake City, Utah, has now appeared on "Jeopardy!" (search) for 10 consecutive nights — a new record for the 30-year-old game show.
Jennings, who broke the previous record of seven consecutive appearances set last January by Tom Walsh, has amassed more than $290,000.
"What he did was not only break the record but also shatter the record for cash winnings [for consecutive appearances]," a show spokesman said.
"He's now been on the show longer than any other contestant."
Jennings has gotten this far through his skill — and with a little help from changes in the "Jeopardy!" rulebook.
Last fall, the show lifted its five-day win limit, allowing contestants to stay on the show as long as they continue to win.
Since he's still a contestant on the show, Jennings isn't allowed to talk to the media. We can tell you, however, that he and his wife, Mindy, recently became first-time parents — and that Jennings works for CompHealth Group.
Jennings' winnings through tonight put him in 24th place among all-time syndicated game show winners in terms of total winnings, according to tvgameshows.net.
That includes nine married couples who snared $1 million annuities on "The $1 Million Chance of a Lifetime" in the 1980s.
