There’s still not a lot of 3D programming on cable or broadcast to satisfy those first buyers of 3D televisions. But IHS Screen Digest says today that the technology is about to find a real foothold among fans of Blu-ray discs. Some 3.2 million homes this year will have the equipment needed to watch Blu-ray discs in 3D. That a 305% increase over last year. The 3D discs can be played on Sony’s PlayStation 3 consoles as well as 3D-enabled Blu-ray players. Hollywood, of course, sees a cash opportunity. Studios will release about 65 titles on 3D Blu-ray this year, IHS says. That total will include 15 from Disney such as Tron, Beauty And The Beast, and The Lion King. As a result, the research firm predicts that US consumers will spend $160.8 million this year on discs that provide 3D images to 3D-enabled TV sets. IHS figures that consumers will buy 5.7 million 3D discs at an average of $28.33 a pop. That contrasts with $28.4 million last year based on 900,000 discs selling for $31.09 apiece. The big reason for the increase is that 3D is catching on with early adopters. IHS adds that 3D discs are catching on in the UK, Germany, and France.
