New data from Home Media Research shows that Blu-ray is continuing to lead in high definition media sales. As of August 5th, the top 10 best selling high definition movies are all available on Blu-ray, and half of those exclusive to the format. Warner Brother's '300' leads the pack, followed by 'The Departed', 'Casino Royale', 'Planet Earth', and 'Pirates of the Caribbean: Dead Man's Chest'.
Noticeably absent from the list is Universal who didn't have a title which sold enough copies break into the top 20. Paramount made it to 17th with their release of 'Babel', but if there wasn't a Blu-ray version of the title, it would have fell well short of making the list. All Blu-ray studios were represented in the Top 20 (including Lionsgate with their release of 'Crank').
