It's a thing you
like, but it doesn't seem to actually be terribly important to making a successful show. (Which is fine, incidentally. I like plenty of things that aren't popular.)
The
10 most popular shows on broadcast TV in the US, as of March:
- Sunday Night Football
- NCIS
- FBI
- Blue Bloods
- Young Sheldon
- Chicago Fire
- Ghosts
- 60 Minutes
- Chicago Med
- The Equalizer
Of those, only Sunday Night Football has particularly deep lore, and they have commentators who will
insist on sharing it with viewers the moment it's relevant, and it's debatable how much viewers care more about what's happening knowing it's only the second time a left-handed field kicker from Notre Dame whose last name ends in a "Y" has kicked three field goals in a single game since 1965.
For everything else, everything else is succeeding based on delivering a satisfying story, of whatever sort, on a weekly basis.
