#20: Laverne & Shirley’s Ratings Begin Cooling by 1980 After its Peak
By 1980, the show was still popular but no longer dominating television the way it had during its peak years. After reaching the No. 1 spot in the ratings earlier in the decade, viewership slowly began declining as new programs competed for audiences.

The shift in ratings signaled that the show had likely passed its commercial peak, even though it continued attracting millions of viewers each week.
