I’d say the window of overlap for “look at the computer” and “information superhighway” was actually pretty small for most people.
Maybe 1996-2001?
So then you factor in how old people would have been during that period who would have done this. Being generous, I’d say 9-18. At different ages in that range “going to my friend’s place to look at the computer” would have been a euphemism for different things.
But the range there would be from 1977-1992, which is actually pretty impressive for a cultural moment. Essentially, most millennials.
I remember use of the phrase "information superhighway" only really existing for a short window around the early days of the WWW while it was still novel and exciting and before it started to become mundane. I'd say you're bang on for the window.
Those were the best days of the Internet, and not just because I was a teenager who'd discovered there were pictures of boobs on it.
