Alex Trebek will host 'Jeopardy!' through 2022

Rest easy, Alex Trebek fans: He's going to be hosting "Jeopardy!" for at least four more years.

Sony Pictures Television announced Wednesday that it had signed the game show's long-term host to a two-year extension through 2022. In addition, Sony handed the two-year extensions through 2022 of "Wheel of Fortune" stars Vanna White, 61, and Pat Sajak, 72.

During a TV interview in July, the 78-year-old Trebek hinted that he might retire in 2020, saying "the odds are 50/50 and a little less" he might leave when his contract expired. Trebek then offered suggestions for replacements — Alex Faust, a Los Angeles sports anchor, or CNN legal analyst Laura Coates. He was treated for a subdural hematoma last December, caused by a fall a couple months earlier, and was off the air for a period.

Trebek has hosted "Jeopardy!" since 1984. The show without him is inconceivable, as Sony indicated in a statement.

 “Pat, Vanna and Alex are simply the best," said Sony Pictures Television chairman Mike Hopkins. "Night after night, they seamlessly entertain generations of fans on two of the most beloved television programs on air. We are thrilled that they’ll continue to do so through 2022."
