It needed to be said because that question makes no sense in the situation of which you ask it. That any demographic or mix of same would necessarily be "dominant" in the context of early Internet culture, indeed even the unitary integrity the phrase "early Internet culture" grammatically implies, is an assumption. As long as you keep that, no history I can recommend is going to help you, because read with that assumption they will also make no sense. (I'll still recommend them, of course; just that I don't see them doing you any good this way.) The scare quotes are because I honestly do not understand what you mean by that term here; I think you and I might be speaking across an ocean, too.
