For many, “The Cosby Show” has become unwatchable since the dozens of sexual assault allegations against Bill Cosby entered the media spotlight. Some networks, such as TV Land, have pulled the show from their lineups. (Others, like Bounce TV, initially did the same, only to resume airing reruns up until the verdict came in this year. It remains available to stream on Amazon Prime Video.)

But “A Different World,” the popular “Cosby” spinoff that ended its original run 25 years ago this week, doesn’t seem to have inspired the same amount of hand-wringing as its predecessor.

Among the many pieces that have been written about Mr. Cosby’s legacy and how we square it with the man himself, few pay much attention to “A Different World,” which he created. And articles about the sitcom — including a spate of them last fall around another milestone, the 30th anniversary of its September 1987 premiere — tend to mostly leave Mr. Cosby’s transgressions out of it. When the “black-ish” creator Kenya Barris added “grown-ish” earlier this year, he openly cited “A Different World” as an influence and expressed hope that his own show could have a similar cultural impact.

Some of the reasons for this continued affection are obvious. While Mr. Cosby’s name appears in the credits for each episode, he only appeared on screen in three of them, all in Season 1. And after that season, which centered on Denise Huxtable’s (Lisa Bonet) transition to university life at the fictional Hillman College, the series was completely revamped.
