Although it will hardly come as a surprise Sony have finally thrown in the towel with their revolutionary MiniDisc format. Originally launched back in 1992 the mini disk was a direct contender to the popular CD. Marketed as being smaller than the CD and skip-free it showed promise. The popularity of CD had been underestimated however and the rise in digital media made the MiniDisc un-competitive. In 2011 sales of portable MiniDisc players ended. The last MiniDisk stereo systems will be rolling off the production lines in March. Its actually quite surprising that the format lasted 20 years.
