Alex Trebek, best known for his decades-long run as the host of "Jeopardy!", passed away at the age of 80. Cancer, that ever-present monster (more specifically pancreatic), was the ultimate cause.
I remember as a kid, "Wheel of Fortune" and "Jeopardy!" would always air in order on the local NBC affiliate starting at 7pm. I wasn't a "fan" of the latter show, but it was still nice to watch from time to time.
