Has Ken Jennings (search) ended his "Jeopardy!" streak?

A report posted Wednesday on TV Week's Web site said the brainy software engineer 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 unidentified sources and said the show would air later this fall.

A representative for the show told TV Week that it would not disclose whether Jennings lost.

Calls late Wednesday by The Associated Press to "Jeopardy!" (search) publicist Jeff Ritter and to the show's production offices were not immediately returned.

Jennings, 30, of Salt Lake City, began his record-breaking run June 2, with a six-week hiatus for summer reruns.

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

To mark the start of its 20th season last September, the quiz show lifted its five-game limit for winners and allowed them to keep going until they lose.
