Saturday Night Live is an American sketch comedy series created and produced by Lorne Michaels for most of the show's run. The show has aired on NBC since 1975. After the 1979–80 season, Michaels attempted to take a break and appoint writer Al Franken his successor. However, then-president of NBC Fred Silverman passed on Franken and gave the job to associate producer Jean Doumanian, bringing in a brand new cast and mostly new writers, and resulting in the most critically unstable season in SNL's history. Doumanian was fired and replaced with Dick Ebersol, who brought in a new cast, keeping only Eddie Murphy and Joe Piscopo. Murphy and Piscopo became breakout stars and restored the show's popularity.
