Since 1984, Alex Trebek has hosted 6,829 episodes of Jeopardy!, and that's a record. As of last night, he holds the Guinness World Record for "most game show episodes hosted by the same presenter," the Hollywood Reporter notes. He's been the host of the show ever since in relaunched; it initially ran from 1964 to 1979 with Art Fleming as host, the Los Angeles Times notes. "It's an honor to hold the Guinness World Record for hosting Jeopardy!, which I've often said is the best of reality TV," he says. Trebek is 73, but he told the Reporter last month that he'd "stick with it as long as I'm having a good time and as long as I feel my skills haven't diminished too much."
