Will & Grace and Roseanne last season helped paved the way for the popularity of the multicamera format this season with shows like The Neighborhood, The Cool Kids, Murphy Brown and spinoff The Conners.

That format never went out unless you don't count The Big Bang Theory, Last Man Standing, Moms ect.
