Season 6 (1989-1990)Edit
- The category cards have a more rectangular shaped appearance, as opposed to previous seasons.
- This is the last season to have the 1983-1990 KingWorld "Stars and Stripes" logo at the end of each episode; the early episodes of the next season have this logo, before changing over to the 1990-1998 KingWorld "Spotlights" logo.
- Alex Trebek started wearing glasses in this season, so that the contestants can have more room.
- Stock footage from the March 16, 1990 episode was featured in the 1992 film Breaking the Rules.
- The short-lived Super Jeopardy! debuted in the summer of 1990, and the Jeopardy! set consisted of four contestant podiums, instead of three. The short-lived Super Jeopardy! ended that same year in 1990.
- On early episodes of this season, the copyright card has a red Jeopardy! logo on it.
- Season 6 of Jeopardy! kicks off on September 4, 1989.
- On the September 12, 1989, episode, Bob Blake sets a new five-day winnings record of $82,501; however, due to a winnings limit of $75,000 in place at the time, Blake was forced to give $7,501 to OxFam.
