I think it's pretty easy to come to the fact that PS2 helped DVD, not the other way around. In pretty much every region it launched in, we have stories of DVD sales skyrocketing, while before the sales were meh, at best. If it was DVD that helped PS2, DVD would have been becoming very popular on their own. Then people saw the PS2 could play DVDs, so they bought it.

Of course, that's not what happened. DVD players were already around half the price of the PS2. No one was picking it up that early in its life for DVDs. What happened was gamers were buying the new Playstation, and knowing it could also play DVDs, they thought "Well, might as well pick up a couple DVDs to test them out."

@ OP

I don't think people are picking up on what you did there. But, yes, PS4 is selling for the same reason PS1, PS2, and, on a slightly smaller level, the PS3. Games. 

By the logic of the OP PS4 only sold good because of PSVR.

Not just with one sentence but the very first sentence lolll xD

You only have 1 chance to make a 1st impression.  It's very difficult to reverse public perception after starting out on the wrong foot.  Microsoft may have quickly reversed its policies, but what they could not reverse was the sour taste they left in the mouths of their target consumers who flocked to Sony.  The PS3's launch woes were primarily price related.  The majority of consumers are not interested in a $600 or even $500 video game console (all the more baffling how Microsoft did not know this after watching their main competitor stumble out of the gate the previous gen).  But a price drop heals this instantly.  Having to walk back disastrously bad policies and PR is a much more difficult wound to heal with the consumer.  

PS2 sold during 12 or so years but was a fad and did sell just because of its dvd capabilities? fucking lol

That unabandoned failure managed to sell 90M and get some very good games.

The X1 reveal was so fever pitch you had to watch it. Although a Sony supporter I've always also had all Microsoft's offerings. Including Xbox one s 

But that reveal for the standard casual gamer rwas a disaster I've never seen anything like it. It's cost Microsoft the whole gen now Sony are getting so far ahead it's almost impossible to fail now with ps5

Doesn't the PS4's controller have a touch pad? Do game's still make great use of that these days? I know it's not a central selling focus at least nowadays, but it's still apart of the hardware that doesn't seem to be highly praised that much.

I'm just saying even Sony like to be a little different with their hardware sometimes, sure it might not always succeed but it's good when companies at least try. As well even the PS4 is not without it's own "fad" although I don't really think that's the best term to call it.

No one ever bought a PS1 because it played CD's hhaha wtf dude? How old was you in around 94,95 to think people actually played CD's on a psone? Ill give you the ps2 with a DVD player though. Ps2 was like the same price as a dvd player when it came out. Bargain.

The "PS1 and 2 only sold that well because they had DVD/CD" argument has never held up and still doesn't.
