Twentieth Century-Fox is sure kicking out the stops for the launch of Digital HD (DHD), its new early-release electronic sell-through initiative. The first DHD title, Ridley Scott’s sci-fi thriller “Prometheus,” is available for download starting today, three weeks before it appears on DVD and Blu-ray. The high-definition downloads will cost $15, roughly half the list price of a Blu-ray disc, and are available from Amazon, Apple’s iTunes, Best Buy’s CinemaNow, Walmart’s Vudu and via Xbox Live and the PlayStation Network. Fox has even put aside its objections to what it regards as Google’s facilitation of piracy and will make DHD titles available via both YouTube and the Google Play store. Links to “Prometheus” on those services will also appear on ESPN.com as apart of a promotion with that nework. Going forward, all new releases from Fox will get the DHD treatment ahead ahead of Blu-ray and DVD.
