As far as Blu-Ray vs. HD DVD goes, it denotes we ‘have passed the point of no return now, with each passing day, it seems less likely that a compromise will be reached on a next format’ (Block, 2005). Toshiba forced to conclude by admitting failure and announcing that they would stop manufacturing HD DVD discs. What I am trying to expound is that not only excellent technologies ensure success, but also other important factors are involved.
In the mid 1990s, high-definition (HD) television sets were becoming increasingly popular. However, consumers were unable to record or play back this HD content because it required a storage medium capable of holding the larger amount of data for HD video. The breakthrough came with Nakamura's invention of the blue laser diode in 1995, making it possible to develop formats to record and play HD visual content (Blu-Ray and HD DVD extract).
Based on Nakamura’s discovery, Sony started to develop projects applying the new diodes. In February 2002, the project was officially announced as Blu-Ray, and the DVD Forum, chaired by Toshiba. The two formats have very similar technologies, besides using a blue laser to read and write data, they use similar methods for encoding media onto discs. However the two competing formats had significant differences that made each incompatible with the other (including older DVD players) despite both formats delivering clear high-definition pictures and sound. However Blu-Ray exhibited superior quality to HD DVD in some technical respects. Compared with HD DVD, Blu-Ray discs have a larger storage capacity, up to 50GB; Blu-Ray discs are encoded with region codes, this means that they have a higher level of security; most importantly, when the Play Station 3 add-on HD DVD drive was launched, Blu-Ray gained a terrific advantage.
Actually, it is impossible that the two formats are in existence at the same time. They are relying on content providers,...
