The whole PS2 succeeding because of the DVD boom is a bit of a history rewrite, which only really popped up after Sony itself claimed around the PS3's launch that the PS2 pioneered DVD. Cheap DVD players were already becoming popular in some households before the PS2 launch - the PS2 didn't seem to have a super tangible effect on this outside of giving gamers an excuse to buy DVDs.
Of course at this point we can't prove either side is more correct with more detailed data that we just don't have, so the PS2 succeeding because of a "fad" is a claim that can just be thrown around!
The PS4 doesn't need to be special compared to the others in the 100m club, it doesn't need an extra ego stroke or to take shots at its older brothers or the Nintendo systems to feel better. If we really want to start defining fads, I can guarantee each of the highest selling systems moved many units to those that don't usually buy systems just due to word of mouth, popularity, or because it was a status symbol. My buddy's non-gamer dad owns a Switch because it's popular, and I believe coincidentally also had a PS2 for that same reason!
You should check out my YouTube channel, The Golden Bolt! I review all types of video games, both classic and modern, and I also give short flyover reviews of the free games each month on PlayStation Plus to tell you if they're worth downloading. After all, the games may be free, but your time is valuable!
