20th Century Fox launched an initiative designed to spur digital sales, offering its sci-fi thriller "Prometheus" for sale through several major online retailers three weeks ahead of the movie's release on DVD and Blu-ray disc.
The Ridley Scott film is one of 600 titles to be sold digitally in high-definition for less than $15 -- a discount from the typical retail price of $20.
The movies are available online through Amazon, Apple Inc.'s iTunes store, BestBuy's CinemaNow, Google Play, YouTube and Wal-Mart's Vudu, as well as through entertainment stores connected to the Sony PlayStation and Xbox game consoles.
"With almost 800 million broadband-connected devices, and millions of people accessing entertainment on these devices, we feel the medium's time has come," said Mike Dunn, president of 20th Century Fox Home Entertainment.
