In the 21 years since Cosby's Huxtable family departed prime time, many (although certainly not all) sitcoms have adopted a much more realistic, even cynical, view of the dynamics of domesticity and the wider world.
Indeed, it was in reaction to Cosby's sugar-coated unreality that the creators of Seinfeld decreed there'd be no learning and no hugging on their series.
While the show featured a group of nihilistic friends, a cohort of family-based comedies that rejected the smug certainties of The Cosby Show also emerged, including Roseanne, Everyone Loves Raymond (a not-so-subtly subversive series written off as Cosby-lite'n'white by those who didn't watch it), Everyone Hates Chris, and Malcolm in the Middle.
The Middle, which makes a welcome return this Monday, belongs to that lineage of shows, which accept the frayed and fractious nature of family ties as quite normal while simultaneously celebrating them.
If you've never watched it, it's well worth a look. About the struggling Midwestern middle class Heck family, the role of wife and mother Frankie is played by Patricia Heaton, who occupied the same position in Raymond, and husband/father Mike is played by Neil Flynn, best known as Scrubs' eternally put-upon janitor.
They're great as barely-holding-it-together parents and the young actors who play the three kids are all terrific too.
The characters are sharply drawn enough that you'll quickly understand the rhythm of this family's life if it's your first encounter with them.
Although the humour often veers towards the zany, like so many American sitcoms, it's strongly enough rooted in emotional truth that it remains recognisably human.
In the hour-long, season four premiere, Frankie becomes obsessed with winning the position of preferred parent. Bittersweet comedy ensues.
• The new series of The Middle starts tomorrow, 7.30pm, on TV2.
