Alex Trebek was best known as the longtime host of the beloved game show “Jeopardy!” 

The Emmy winner, who first took on the role in 1984, became an institution, so much so he occasionally guest-starred on other TV shows including “Cheers” and “The Golden Girls.”

Trebek died Sunday at 80 years old after battling pancreatic cancer. He was diagnosed in March 2019 and even kept up with his hosting duties while undergoing treatments.

Representatives for "Jeopardy!" said in a statement that the show will not announce plans for a new host at this time.
