To celebrate Jeopardy!'s 30th anniversary season in syndication, the show unveiled a new set:
The sliding doors behind the host and the contestants were removed from the set, so the ramp behind the game board was added. There are borders on the game board, on top of that, there are three strips and rectangular posts on the sides, which look just like the ones used on its sister show Wheel of Fortune.
The host's podium gained a new look containing strips; and for the first time since the Art Fleming era, the Jeopardy! logo was added to the host's podium. The piano key LEDs were removed from the set, so the contestant podiums were raised to create a single floor. The contestant podiums retain the sideway monitors. The large monitor between the host and the contestants were modified.
This set is still in use to the present day, despite getting modified several times since Season 37.
The opening sequence changed to red spheres on a purple background and meandering lines revealing a CGI rendering of a globe, making the green lands on the blue globe appear; the globe intro makes a comeback on a blue, pink, and orange gradient background. The white Jeopardy! logo and a white "30th Anniversary" byline zoom out to reveal the set.
However, the graphic cards look different, it has the same background as the opening title card, but there is no globe at the bottom, it's just a blue floor.
On early episodes of this season the "FINAL" in Final Jeopardy! is yellow. Later in this season, the text is changed to red.
The backdrop for picture clues, Daily Doubles, on-set branding, and split screen closing credits on episodes with a full credit roll, changed its color to a blue starry background, appearing similar to the one used in Season 24.
Just like in Seasons 26 and 29, there are no road shows to tape. All 230 half-hour episodes are taped in Culver City.
This is the last season until Season 37 to end its original run in August, rather than July.
It is the season that produced the most female champions with five or more wins in a row (4 people) among all seasons, and it is the only season so far that the number of female champions with five or more wins or more exceeds that of male champions.
This is the sixth season not to have Tournament of Champions.
