A "Jeopardy!" spokeswoman said Trebek, 67, had the heart attack Monday night at his home in the Los Angeles area but did not disclose any further details.

A post on the official "Jeopardy!" website said Trebek was "resting comfortably in a Los Angeles hospital, and he will be back in the studio for the next scheduled tapings in January."

"Jeopardy!," a general knowledge quiz, is one of the longest running game shows on U.S. television and regularly places No. 1 in ratings among its rivals. It reaches nearly 39 million viewers a week and airs in over 99 percent of the United States.

The Canadian-born Trebek has been its host since 1984. Prior to becoming "Jeopardy!" host, he served as emcee for a number of game shows, including "High Rollers," "The Wizard of Odds" and "Battlestars."
