I haven't heard anyone talk about this, but the PS2 was the first time I recall seeing a blue LED in a consumer product. I remember being really wowed by it, as just a few years prior I saw 5mm blue LEDs being sold in an electronics hobby catalog for $95 each.

I've mused about this a few times over the years (e.g. https://twitter.com/cederman/status/641507163639148544), and it is interesting how big a deal it was at the time on gaming forums.

A DVD player was a major selling point for some people when they bought the PS2. For others, myself included, it was the blue LED.
