I think Blu-Ray won because you can't abreviate HD DVD, its already abreviated. So when going on and on about 1 format or the other it was just easier to say, 'I watched a fabulous BD today on my new BD player. The BD quality was excellent, I love BD's"!!! Than to say, "I watched a fabulous HD DVD today on my new HD DVD player. The HD DVD quality was excellent, I love HD DVD's"!!! See what I mean?
So forget about Sony's deep pockets, double & triple layer discs, security issues and all that nonsense. HD DVD just had too long of a name!
