Jeopardy! host Alex Trebek died early Sunday morning, officials reported.
He reportedly passed away at home, surrounded by his family and friends, according to a post on Twitter.
There is no initial information about his cause of death.
Trebek presided over the beloved quiz show for more than 30 years.
He was a master of the format, engaging in friendly banter with contestants and appearing genuinely pleased when they answered correctly.
He was also able to move the game along in a brisk no-nonsense fashion whenever people struggled for answers.
The Canadian-born Trebek was more than qualified for the job, having started his game show career on “Reach for the Top” in his native country.
Moving to the U.S. in 1973, he appeared on “The Wizard of Odds,” “Classic Concentration,” “To Tell the Truth,” “High Rollers,” “The $128,000 Question” and “Double Dare.”
