Moore's show proved so popular that three other regular characters, Valerie Harper as Rhoda Morgenstern, Cloris Leachman as Phyllis Lindstrom and Ed Asner as Lou Grant were also spun off into their own series, and again featured Brooks and his former production partner Allan Burns as producers. The premise of the single working woman's life, alternating during the program between work and home, became a television staple. After six years of ratings in the top 20, the show slipped to number 39 during season seven. Producers asked that the series be canceled because of falling ratings, afraid that the show's legacy might be damaged if it were renewed for another season. Despite the decline in ratings, the 1977 season would go on to garner its third straight Emmy Award for Outstanding Comedy. During its seven seasons, the program won 29 Emmys in total (Moore herself winning three times for Best Lead Actress in a sitcom). That record remained unbroken until 2002, when the NBC sitcom "Frasier" won its 30th Emmy.
