According to the New York Times, Fox is about to try another tactic to enhance sales of its movies, by offering downloadable UltraViolet copies for sale a full three weeks ahead of their release on Blu-ray / DVD or for video on-demand rental. The first movie to get the treatment will be Ridley Scott’s Prometheus later this month, and Fox is pricing the copies at about $15, down from the $20 of previous releases. Other flicks on deck for the early digital sale treatment are Abraham Lincoln: Vampire Hunter, The Watch and Ice Age: Continental Drift. Fox is apparently calling the setup Digital HD, or DHD, as it rolls out in 50 different countries all at once. Read the full story at Engadget.
