Comparison of high-definition optical disc formats

This article compares the technical specifications of multiple high-definition formats, including the now obsolete HD DVD and still in-use Blu-ray Disc; two mutually incompatible, high-definition optical disc formats that, beginning in 2006, attempted to improve upon and eventually replace the DVD standard. The two formats remained in a format war until February 19, 2008, when Toshiba, HD DVD's creator, announced plans to cease development, manufacturing and marketing of HD DVD players and recorders.
