LOS ANGELES – At the third annual 3D entertainment summit in Los Angeles, speakers like M. Night Shyamalan and Jefrey Katzenberg headlined the two-day event. The key takeaway from the sold out summit, which had over 800 attendees, was that 3D, though still an embryonic industry, is poised for explosive growth and will become the major force in entertainment moving forward. Chris Cookson, president of technology at Sony Pictures Entertainment, talks about the future of 3D in this keynote video.
