Parent comment was (I think), specifically talking about sitcoms from what I understood.
Sitcoms are - and I know this is a little condescending to point out - comedies contrived to exist in a particular situation: situation comedy → sitcom.
In the old day, the "situation" needed to be relatively relatable and static to allow drop-in viewers channel surfing, or the casual viewer the parent described.
Soap operas and other long-running drama series are built differently: they are meant to have long story arcs that keep people engaged in content over many weeks, months or years. There are throwbacks to old storylines, there are twists and turns to keep you watching, and if you miss an episode you get lost, so you don't ever miss an episode - or the soap adverts within them, their reason for being for which they are named - in case you are now behind with everything.
You'll find sports networks try to build the story arc around games too - create a sense of "missing out" if you don't watch the big game live.
I think the general point is that in the stream subscription era, everything has become like this "don't miss out" form, by doubling down on the need to see everything from the beginning and become a completist.
You can't easily have a comedy show like Cheers or Married... With Children, in 2026, because there's nothing to keep you in the "next episode" loop in the structure, so you end up with comedies with long-running arcs like Schitt's Creek.
The last set of sitcoms that were immune to this were probably of the Brooklyn 99, Cougartown and Modern Family era - there were in-jokes for the devotees, but you could pick up an episode easily mid-series and just dive in and not be totally lost.
Interesting exception: Tim Allen has managed to get recommissioned with an old style format a couple of times, but he's had to make sure he's skewing to an older audience (read: it's a story of Republican guys who love hunting), for any of it to make sense to TV execs.
