And I remember very well the words "blue laser" used for describing that technology.
Describing [i]what[i] technology? Are you implying that George Lucas invented Blu-ray in 1983, before even MPEG had been invented?
At best, perhaps, he was getting excited about someone else's idea for, say, an improved laserdisc using a blue laser. Extrapolating that to Blu-ray is like claiming Henry Ford invented the Tesla Roadster.
