They actually were, but I'd question how many people actually knew about it.
I was 15 with no credit card so i didn't know about them !
The only reason i even invest in bluray is because DD are so screwed up.
I can take my bluray and load it onto my home server and watch it anywhere in my houes and anywhere i have internet connections. until dd offers me that i will be forced to buy blurays.
of course i'm sure i'm not using the blurays as the movie studios want. i'm sure they'd want me to have to buy it on every media device i have and then when they become obsolete they'd want me to rebuy it again.
