I was born in 92. My childhood (part of it, anyway) was in the 90s and I do remember the latter half of them fairly well. These things are never really clear cut, especially for people born around the “change” in generations.

Outside is where the mosquitos live.

I read the books first, and while there are plenty of omissions and outright changes from the source material that I disagree with, cutting Tom Bombadil is not one of them.
