Spurred in part by the sale of 2 million PlayStation 3 consoles, Sony officials have claimed that, according to research data, cumulative sales of Blu-ray discs have surpassed those for HD-DVD for the first time.

According to Nielsen VideoScan, the consumer research firm for the VHS and DVD sell-through industry, in addition to an overall lead in sales to date, Blu-ray movies outsold those released for the HD-DVD format by more than a 2-to-1 margin during the first week of January. This equates to 47.14 HD DVD titles sold for every 100 Blu-ray titles.

The report also found that Blu-ray titles outsold HD-DVD releases by nearly a 3-to-1 margin during January's second week, with 38.36 HD-DVD titles sold for every 100 Blu-ray releases.

Sony officials also revealed that, according to an online survey of approximately 100,000 current PlayStation 3 owners conducted by the company, 90 percent have watched a Blu-ray movie on their console.

This high percentage is likely helped by the bundled Talladega Nights Blu-ray disc with the first 500,000 units of PlayStation 3. But even apart from that, 80 percent of those surveyed plan to purchase further Blu-ray movies, while 72 percent of respondents stated that they plan to rent a Blu-ray movie in the near future.

Doesn't surprise me one bit.

I predicted months ago in the "Blu-Ray vs HD-DVD" thread that this may happen.
