Why Did Blu-ray Win the Format War?
A format war describes competition between mutually incompatible proprietary formats, typically for data storage devices and recording formats for electronic media such as the format war between the Blu-ray Disc and HD DVD optical disc standards for storing high definition video and audio. These standards emerged between 2000 and 2002 and attracted both the mutual and exclusive support of major consumer electronics manufacturers, personal computer manufacturers, television and movie producers and distributors, and software developers.
Several disc formats that were initiated to better the performance on DVDs were developed, among which Blu-ray by Sony and HD-DVD by Toshiba are the most popular ones. The first HD-DVD player released in March 2006, Sony followed its step with the first Blu-ray player. Later but not worse, Sony was in the green tree because Warner Brothers supporting HD-DVD announced to stop releasing HD-DVD films in 2008. Subsequently, many other retailers in North America claimed to support Blu-ray only. Thus Blu-ray won the format war.
Then why did Blu-ray win the war?
Firstly, Blu-ray has much larger storage capacity. The storage capacity of a single-layered Blu-ray disc is about 25 or 27GB while that of a double-layered one can reach 46 or 54 GB. It is also possible to get four-layered or even eight-layered ones the storage capacity of which can respectively reach 100 and 200 GB.
Secondly, Blu-ray has higher compatibility. According to Blu-ray Disc Association (BDA), all accredited Blu-ray players are able to play DVD-ROM, VCD and CD. In some aspects, we can say that HD-DVD can be replaced by Blu-ray because Blu-ray has possessed some of the advantages that have been had by HD-DVD only.
