The emergence of high definition players followed the entry of HDTV televisions into the mainstream market in the mid-2000s. Consumer-grade high definition players required an inexpensive storage medium capable of holding the larger amount of data needed for HD video.[3] The breakthrough came with Shuji Nakamura's invention of the blue laser diode,...
