Movies or TV shows you didn't realize were not set during the time they were made

I just found out Freaks and Geeks, that was made in 99/2000 was actually set in 1980. Never noticed it before.
Can we stop the mirrors before this becomes a whole thing pls?

Sooooooooryyyyyyyyy your majesty.
Didn't realize the Internet was running out of data already
I know. I surprise even myself being bothered by it. I thought I was cooler than this.

Fwiw I legit don't have a single response for any of them so that may be part of it.
