This story about the show's stop at Fort Campbell, KY offers the most detail on the quizzer and its creator, Steve Sellers.
The show will tour 16 bases, leading up to a tournament of champions at Fort Sam Houston, TX in the fall. It's sponsored by the Super 8 motel chain and run by Army Entertainment. Which sounds like well disciplined entertainment.
There aren't many details on the actual gameplay, except that it helps to know a lot of stuff. Sgt. 1st Class Nolan Barringer won the show at Fort Campbell, and his wife lauds his trivia prowess. "One time, 10 years ago, I beat him at Jeopardy. One time. Other than that he is the trivia master."
Steve Sellers, the host and creator of the show, has nothing but praise for the military. "I'm a former schoolteacher and I have several students who are currently and have served active duty and just hearing their stories really inspired me. The fact that somebody would be willing to put themselves in harm's way so we can be free because they believe in our country is humbling."
I expect to see more stories about the show in the military press. It's not every day that a live game show comes to a military base.
