Warner Home Entertainment has a reason to be proud, as their movie, The Departed, has sold over 100,000 units since its release in February, effectively becoming the first movie to reach that milestone. This accomplishment was helped by the fact that they support both HD-DVD and Blu-ray formats.
While Warner is not the only format-neutral studio, it has been the most aggressive, releasing more titles than any other studio, and even planning to release (and license to other studios) its own hybrid format (dubbed “Total Hi-Def”) sometime later this year.
