I remember its rival, HD DVD, and how Microsoft bet on HD DVD. The Xbox 360 had an expensive add-on that enabled the use of the discs. No games supported it.
Meanwhile, the PS3 shipped with a Blu-ray player in it and retailed for about half of what Blu-ray players were going for, in 2007. Just like PS2 helped push DVD adoption (though it was well on its way when the PS2 came out), the PS3 definitely contributed to Blu-ray. Both formats offered promising results, but only one was given away with every PS3.
