'Jeopardy!' Host Alex Trebek: A Remembrance : Pop Culture Happy Hour The game show host Alex Trebek died Sunday following a battle with pancreatic cancer. Trebek hosted Jeopardy! for 36 years — his last episode airs on Christmas Day. Trebek hosted a number of game shows dating back to the early '70s. But he'll be forever known for his work on Jeopardy! — both for his steady demeanor and for moments when he couldn't bring himself to suffer fools gladly.
