Has Ken Jennings ended his 'Jeopardy!' run?

Via Slashdot. SFGate has an article saying:

A report posted Wednesday on the TV Week Web site said the brainy software engineer from Utah lost in a show taped Tuesday, walking away after his 75th straight game with about $2.5 million overall in cash and prizes. The magazine cited unnamed sources and said the show would air later this fall.

After winning the show that aired Wednesday, his 41st, he had amassed $1,380,661.

That's a lotta moolah.
