 1992 and 1993 saw great changes in late-night talk shows: Jay Leno took the place of Johnny Carson, David Letterman switched networks and time slots, and Chevy Chase and newcomer Conan O Brien started their own shows. After the dust cleared from the greatly-hyped "talk-show wars", Chase emerged as the undisputed loser. While the show s format differed little from that of its competition, and a star of Chase s caliber had no trouble finding well-known guests, the show simply failed to resonate with viewers, and ground to a humiliating halt as it was finally pulled off the air in mid-show.
