Nostalgia is too big a force in pop culture to belong to any one institution. But Netflix owns a bigger percentage of it than most, simply because the past is built into its business model.

“If you liked that, you’ll like this” is the watchword of the streaming service’s algorithm. But it’s also the essence of cultural nostalgia: the longing to find some “this” that reproduces the cherished pleasures of some long-ago “that.”

As Netflix has shown us, there are different ways to chase the thrills of yesterday. You can reboot it, as when “Fuller House” brought the characters of “Full House” into 2016. You can revive it, as with the coming continuation of “Gilmore Girls.”

Or — as in Netflix’s two throwback shows of the summer, “Stranger Things” and “The Get Down” — you can rethink it.
