In 1984, when Jeopardy! returned on to television, the main theme track was altered from that of the 1984 pilot to become more electronic. The original version of "Think!" was used for Final Jeopardy!. The main theme was remixed with a bongo track for the 1991-1992 tournament games. The remixed version was used full time starting in the 1992-93 season. In 1997, an all-new arrangement for both the main theme and the Final Jeopardy! Round "Think!" music made, with jazzy orchestral arrangements by Steve Kaplan. The main theme was updated again in 2001, with arrangements similar to the previous version. In 2008, an all-new arrangement of both the main theme and "Think!" music was created for the 25th season by Chris Bell Music, Inc. The theme has gone through some slight re-orchestrations since the beginning of the 25th season. Starting October 13, 2008, Jeopardy! began using a different track (from the same package) of the "Think!" music from time to time until it eventually replaced the previous version. The newer version used a piano lead.

Beginning with the second season in 1985, the set background would change from blue to red in the Double Jeopardy! and Final Jeopardy! rounds. This practice was discontinued in Season 14 on October 6, 1997, although, on the Celebrity Jeopardy! Sportscasters episode that aired on January 23, 1998, the set did change to red in those rounds. Starting in 2002, with the debut of set#4, the set background changing to red for Final Jeopardy! However, the practice wasn't reinstated for Double Jeopardy!.

During the first season, the show was taped at Metromedia Studios. The next year, they moved to Hollywood Center Studios, where they would be until 1994. The show has been taping at Sony Pictures Studios since 1994.
