The greatest technical innovation for the video disc was the addition of digital stereo sound
using exactly the same system as CDs. At this point, the format was re-released - this time
with a name that finally stuck. Hail the Laserdisc!
Today's Laserdisc format is a 12in double-sided disc, LP in size, but with a CD's shiny surface,
analogue video quality far better than that of VHS, S-VHS, Hi-8 or Betamax video tape,
and CD-quality digital stereo sound.
