The 1970s began with the decline of rural-based shows (such as "The Beverly Hillbillies", "Green Acres" and "Mayberry RFD") and the rise of socially conscious programming (such as "All in the Family", "M*A*S*H" and "Maude"). The resulting change also spurred the return of live audiences, starting with "Here's Lucy" (CBS, 1968–1974), which starred Lucille Ball and served as a prototypal impetus to the new subject matter, and ultimately "The Mary Tyler Moore Show" (CBS, 1970–77). The series' pilot episode, "Love is All Around", had been initially filmed using the single-camera method. The results were not satisfactory to Moore or the producers, who then decided to shift to multiple cameras. Since the first several episodes were taped in late summer, the pilot's first taping was not received well due to bad insulation and poor audio. The second taping, however, provided better air conditioning and a better quality sound system to the stage. Critical reception thus improved, and the show used the multi-camera format thereafter, and became a major success during its seven-year run.
