Arguably the PS2 helped propel DVDs too, in a way neither may have had the success without the other. DVDs had been around for around five years and the wider public wasn't all that interested, they reacted the pretty much the same as they had with Laser Disks and VCDs. High price and that loop of, not many hardware sale-->not much media creation-->not many hardware sales, meant they where pretty limited in their market penetration. Suddenly with the PS2 millions upon millions of homes suddenly had a DVD player so more movies where released on DVD, more people went and got a PS2 for the DVD player so then manufacturers scrambled to make DVD players cheaper and cheaper. By 2003 DVD players could be bought for as little as £30.VladG said:But funnily enough, the PS2 sold a ton of units on the strength of it's DVD player, not it's gaming capabilities, especially early on, creating the critical mass which in turn encouraged game development, which kept snowballing the initial success..
Without the PS2 that might never have happened, the PS2 didn't just spread games it made a media format too. Last gen Microsoft and Sony tried to do the same, Microsoft with the media extender, HD-DVD and streaming and Sony with the PS3s Blu-Ray.
