Home Media Magazine’s research branch, Home Media Research, announced that the between January 1 and September 30 Blu-ray sold 2.6 million units versus a total sales of 1.4 million HD-DVD discs.

This announcement, which indicates an almost 2 to 1 ratio of Blu-ray sales to HD DVD, was a bit of a killjoy for the HD DVD camp who were thrilled by the record setting success of Transformers on HD DVD. Through September, a total of 3.01 million Blu-ray discs have been sold and 1.97 million HD DVDs have been sold according to Home Media Research.

HD DVD is the next generation hi-definition format developed by Toshiba Corp. The format is also supported by Microsoft, whose Xbox 360 console has an expansion which allows it to play HD DVDs. HD DVD also has the support of Time Warner Inc’s Warner Bros, Paramount Pictures and DreamWorks Animation SKG Inc — the latter two of which have signed deals to exclusively provide HD DVD for the next 18 months.
