High-Definition Format Wars: Blu-ray vs. HD DVD

When it comes to the high definition format, you should think of the Blu-ray first. But before, there was a big format war waging between HD-DVD and Blu-ray to fight for the dominant media standard for content in high definition.
Actually, apart from the two main high definition systems, there are other competitors, such as Taiwan's FVD (Forward Versatile Disc), China's EOD (Enhanced Video Disc), and so on. But here, we will focus on the Blu-ray vs HD DVD battle to know how Blu-ray win the high-definition format war.

Overview of the Format War between Blu-ray and HD DVD

The first high-definition television was released in 1998, but they didn't gain popularity until the 2000s after becoming more affordable. During this time, in response to issues with scaling DVDs into a higher resolution format, there was a desire in the industry to create a new, high-definition, optical disc-based video format.
Afterwards, Sony pioneered the Blu-ray format, and with support from companies like Philips, Apple, Dell, and Panasonic, the format was established by the collective Blu-ray Disc Association. Toshiba pioneered the HD DVD format, which had backing from companies like Microsoft and was established by the DVD Forum. They all hope that their format would become the standard so a war was inevitable.
Competitive advantages of HD DVDCompetitive advantages of Blu-ray

1. Low manufacturing costs

2. Cheaper products

3. Flexibility to easily have HD and   conventional version on the same DVD

1. Better product quality

2. Large storage capacity

3. Added security

4. Higher availability

After years of development and attempts to create a single standard, the format war reached consumers in 2006, when the two formats were released two months apart. And finally, Blu-ray win the war while HD DVD was officially discontinued in 2008.

Reason why Blu-ray Win the War

There are mainly two reasons that people want to convert BDMV to MKV or MP4:
1.Capacity is the key. Blu-ray had 40% more capacity and PS3 as backer. HD DVD had nothing special to counter with.
2.Gain traction from the big studio like Disney, Fox, MGM, Warner Bros, etc.
3.Wal-Mart supermarket and online rental company Netflix both announced plans to support Blu-ray exclusively, and at the same time, the death of HD DVD format.

PriceMore expensive than HD DVDNot so expensive
I think the big difference between Blu-ray and HD DVD is the cost. Usually, the Blu-ray disc is more expensive than HD DVD. In addition, the cost of Blu-ray player is also expensive. But Blu-ray devices have been designed to be backwards compatible with both DVDs and CDs, so there should be no problem playing your old collection of movies and music on Blu-ray player.
