Step 1 : Introduction to the question "Which game show took an unsuccessful spin as a late-night talk show host in 1989?"
The Pat Sajak Show was a late-night television talk show which aired on CBS from 1989 to 1990. The show was hosted by Pat Sajak, best known as host of the game show Wheel of Fortune. In order to do the talk show, Sajak left the NBC daytime version of Wheel, but remained the host of the syndicated nighttime version. On April 9, 1990, CBS announced the cancellation due to low ratings, which were generally half the level of Carson's, and were further diminished by The Arsenio Hall Show, which had been launched the same month as Sajak's show.
