Season 23 (2006-2007)Edit

Season changes:

  • Both Jeopardy! and Wheel of Fortune began broadcasting in high definition television.
  • Merv Griffin died of prostate cancer on August 12, 2007, at the age of 82. He created two game shows, such as Jeopardy! in 1964, and its sister show Wheel of Fortune in 1975. King World went out of business on August 20, 2007, to become CBS Television Distribution, which currently produced other syndicated shows.
  • This is the last season to be produced by KingWorld, which had been distributed since the first season.
  • The opening credits have changed to a blue starry background, where many photographs are seen throughout before the Jeopardy! logo came into view. When Johnny Gilbert said "This is Jeopardy!", the Jeopardy! logo came into view, and is set on a starry blue and orange background with a grid pattern, with the Jeopardy! logo in blue. Finally, the Jeopardy! logo then zooms forward, in which the "A" reveals the 2002-2009 set.
  • The gameplay round, and Daily Double title cards changed its color to a starry blue background with the text appearing in orange.
  • The contestant intros and Final Jeopardy! winnings strip change its color to black with white borders and use Franklin Gothic.
  • Korinna is not used on video clues, as well as in the Final Jeopardy! segments; these are changed back to CG Omega, and continued to use that font to this day.
  • The position labels in the closing credits, as well as the copyright notice and the "Created by Merv Griffin" text, have their strips removed, and all credits from Executive Producer to Senior Technical Supervisor/Coordinating Producer have their font changed to Helvetica.
  • Lisa Finneran, Rocky Schmidt, and Gary Johnson are promoted to supervising producers.
  • Also, on this episode, which aired on November 6, 2006, Johnny Gilbert is credited as the announcer for the first time, and technical supervisor Bob Sofia became an associate producer.
  • The set receives a few minor facelifts to accommodate the transition to HDTV.
  • New contestant podiums were added to the set; the contestant podiums were spaced wider apart so that a camera shot can be trained on a single contestant within a 16:9 ratio frame without showing the other contestants on the sides of the screen.
  • The game board is now consisted of a nearly seamless projection wall.
  • Also, during the first two weeks of taping, the ring-in lights on the contestant lecterns are in red LED.
  • In the first full closing credit roll episode of the season, the split-screen background changes to a blue starfield with light blue bars, one on the top and one on the bottom, with the Sony Pictures Studios credit scrolling to a stop on the center-right.
  • On later full credit rolls of this season, the Sony Pictures Studios credit fades in at the center-right.
  • The last KingWorld logo first appeared on the December 25, 2006 Christmas episode, before KingWorld closed its doors. In this version, the 1998-2006 logo graphic was remade in 3D with silver trim in the background, the logo text was tilted, and the sky in the background was changed from golden brown to blue and white.
  • The last KingWorld logo, however, does not begin to be used by Jeopardy! until the December 25, 2006 Christmas episode.
