Generations of fans around the world who welcomed Alex Trebek into their homes for decades are collectively mourning after the Jeopardyhost passed away at the age of 80 on Sunday.

According to CNN, the cause of death was not immediately known, but Trebek announced his battle with stage 4 pancreatic cancer last year. The show announced the passing on their Twitter page. 

"Jeopardy! is saddened to share that Alex Trebek passed away peacefully at home early this morning, surrounded by family and friends," the game show's Twitter account stated. "Thank you, Alex."

The game show host inspired people of all backgrounds with his craft and personality.

Journalist Jemele Hill shared one of her favorite memories from the show.

The contestants of Jeopardy! also recalled their unforgettable interactions with the host.

ESPN highlighted Trebek's message to Kobe Bryant, another icon who died earlier this year.

Trebek, who had been overwhelmed by the love of his fans on a few occasions, had another one of those moments when a contestant wrote a special message during the show.

There's no doubt that the man was a fixture in the house of millions of families.

For many viewers who have watched the show for years, the feeling of answering a Jeopardy! question has always been uplifting.

The beloved entertainer has also been noted for the rap lyrics he reads.

Trebek vowed to fight the disease when he announced his diagnosis last year, CNN reported.

"Now, normally, the prognosis for this is not very encouraging, but I'm going to fight this. And I'm going to keep working and with the love and support of my family and friends — and with the help of your prayers also — I plan to beat the low survival rate statistics for this disease," he said.

The 80-year-old hosted Jeopardy! since 1984. 

"Truth told, I have to [keep hosting] because under the terms of my contract, I have to host Jeopardy! for three more years," Trebek said while battling the disease. "So help me. Keep the faith, and we'll win. We'll get it done."

As Blavity previously reported, Trebek sent encouraging words for U.S. Representative John Lewis, who was also battling cancer.

"We’re starting a new year, and let’s see if we can’t both complete the year as pancreatic cancer survivors," he said to the civil rights champion.
