Season 19 premiered on September 25, 1993 with host Charles Barkley and musical guest, Nirvana. The season's finale was hosted by Heather Locklear with musical guest Janet Jackson on May 14, 1994 and concluded with the cast singing So Long, Farewell, as it was the final season for Phil Hartman, Rob Schneider, Julia Sweeney, and Melanie Hutsell also did not return for season 20.
Norm MacDonald, Jay Mohr and Sarah Silverman made several appearances during monologues earlier on in the season before being added as featured players to the cast; veteran comic actor Michael McKean also joined the cast mid-season as a repertory player for the final six episodes. Silverman did not stay for the following season.
The previous system of organizing the cast into three categories was abolished, with all five members of the middle group upgraded to repertory status.
