A report by Screen Digest says that a recent survey from Warner Home Video found that more U.S. households are using their PS3s to play Blu-ray movies. PS3 users spent 15 percent of their console time devoted to Blu-ray movies in the last quarter of 2007, but spent 23 percent of their time during the first two months of 2008 doing the same activity. Additionally, households using the PS3 as a Blu-ray movie player increased from 53 percent in September 2007 to 80 percent in early 2008.

Still, Screen Digest had some doubts about the significance of the statistics: "The timing of the Warner research, which was carried out in late 2007 and early 2008, means it is impossible to quantify how much the usual Christmas gift-giving season (and subsequent increase in new BD homes) would have increased consumer spending on BDs without the promotions - or, indeed, whether the uplift is sustainable. Furthermore, the relative lack of strong games titles for the PS3 over this period is also likely to have contributed to the console’s use as a BD player. Nonetheless, the sheer size of the PS3 installed base means that even a minimal increase in average per household BD buy rates could have a substantial impact on total hi-def software sales, a fact which played a major role in Warner’s decision to abandon Toshiba’s HD DVD format in favour of Blu-ray earlier this year."
