“Jeopardy!” has long been ruled primarily by broadcast TV. As a staid, reliable quiz show that had the same host for 36 years, viewers have grown to depend on it at a certain time, on a certain channel.

But on Tuesday, Sony Pictures Television, which produces the show, announced a new spinoff — a pop culture edition — that will be streamed only on Prime Video. The spinoff, called “Pop Culture Jeopardy!,” is part of a yearslong expansion of what the show’s producers have called the “Jeopardy!”-verse, as they have pushed new spinoffs and tournaments to shake up the brand, while also avoiding any major changes to the main show that might rankle its most devoted fans.

The announcement about the new spinoff said contestants would compete in teams of three. Some of the topics that might come up, it said, include alternative rock music, “The Avengers,” Broadway, mixed martial arts and high-profile celebrities such as Zendaya.

Under Michael Davies, who has been an executive producer of “Jeopardy!” since 2021, “Jeopardy!” has undergone a wave of expansion, featuring a new masters league with the show’s most successful players, a Second Chance Tournament that invites back promising contestants and a revival of “Celebrity Jeopardy!”

It has not yet been announced who will host the pop-culture spinoff. Since the death of the show’s longtime host, Alex Trebek, in 2020, the succession process has been somewhat tortured. The initial plan to promote the show’s executive producer, Mike Richards, to host imploded after revelations that Richards had made offensive comments on a podcast. For a while, the actor Mayim Bialik split hosting duties with Ken Jennings, the show’s former champion, until Bialik abruptly announced late last year that she had been removed, leaving Jennings as the sole host, at least for now.

“Jeopardy!” has had limited ventures into streaming before now. Viewers can stream some “Jeopardy!” episodes on Pluto TV, and the prime-time spinoffs stream on Hulu the day after they first air. The show used to have a sports trivia spinoff that could be found on Crackle, an online streaming service that never quite took off.
