Ken Jennings is known as the "Jeopardy!" G.O.A.T.

In 2004, he set an untouchable win streak.

He won 74 games in a row.

The result was a lasting friendship with late host Alex Trebek.

Trebek passed away on November 8, 2020.

Ken Jennings was the first to take over after Trebek passed.

He is now returning as host on the anniversary of Trebek’s passing.

It is not clear how long he will be hosting for.

"Jeopardy!" has yet to name a permanent host.
