There was an interview recently on NPR with Mike Shur where he talks about why sitcoms tend not to get made anymore.

Basically, under the new market conditions of streaming no studios are willing to greenlight the production of a sitcom the way they used to be. 22 episode seasons where the writers have the opportunity to flesh out the vibe and characters of the show. That old model usually lost money upfront but then made shitloads back once the show went into syndication.

Instead, all the studios want 10 episode seasons of sitcoms that never get the chance to get off the ground or take their time to develop. They then sell the streaming rights to as many places as possible, kind of like syndication except for that it makes way less money. The whole thing is a race to the bottom and they generally wont take a chance on anything. Instead they would rather fund the hundred-millionth police-action-drama because, unlike comedy, that kind of content tends to be universally understood across cultural lines around the world. Everybody understands cops chasing bad guys, but what is or isnt funny depends on cultural perspectives.

So ultimately we have ended up in this world where sitcoms are still among the most widely consumed content, but virtually everyone watching them is watching sitcoms that ended 10-20 years ago.

That said, I do like most of the new sitcoms I have seen that managed to get made in this sitcom enshitification era
