Yep. IBM's holographic data storage research had some significant technical successes, but interest declined after it became pretty clear that it would not compete with the improving price/performance of existing storage technologies. Here's a link to an article that sums up many of the challenges: http://www.techradar.com/us/news/computing-components/storage/whatever-happened-to-holographic-storage-1099304
Still, I enjoyed producing informative articles and dramatic photos, such as this one -- http://vig.extremetech.com/media/images/16655.jpg -- for IBM's research news reports.
