It's not like having closed campaigns with a beginning, middle and end point was some rare thing that never appeared until 2000 when Paizo started doing Adventure Paths.
Closed campaigns like that was default way we played over 20 years ago in HS. It just made sense. And we played homebrew settings and adventures since published adventures were hard to come by and expensive and we really had no ideas that magazines like Dungeon or Dragon even existed. I saw few times White Dwarf magazine in bookstore that had some foreign magazines but price was ridiculous ( 3-4x times original retail price). When fast internet came around in 2005/6, we mostly relied on scanned pdf and those were for most part books with player options or occasional setting book.
Published adventures were more USA/UK thing. In eastern/south eastern Europe, make your own adventure and setting was usually only option.
