Why Blu-ray?

In the middle of June 2006, the first blu-ray discs were born, and released on the 2oth of June, 2006. As we know, Blu-ray is the future (or as i see it coming), but the question is why blu-ray? isn't there any one that tried to top the new blue laser technology?

Toshiba, a famous Japanese company, that for sure everybody heard about because of their great reputation in making laptops and other computer-related devices, created a new disk storage technology, the Hd Dvds (High-Definition Digital Versatile Disc). 'HD DVD is derived from the same underlying technologies as DVD. Since all variants except the 3x DVD employed a blue laser with a shorter wavelength, it can store about 3¼ times as much data per layer as its predecessor (maximum capacity: 15 GB per layer instead of 4.7 GB per layer).' http://en.wikipedia.org/wiki/HD_DVD#Disc_structure

So? Which is better? Which 1 are we going to use in the future?

On Tuesday, February 19, 2008, Toshiba announced that it was to drop its format in the HD DVD 'war' with Sony, pioneer and other participated companies. The "High definition optical disc format war". In January, 2008, the main company supporting HD DVD — announced it would no longer develop, manufacture and market HD DVD players and recorders, which holded the blu-ray as victorious.
