AOL today announced that it has signed partnerships with several Hollywood studios to offer full-length movie downloads for $9.99 to $19.99. AOL made deals with 20th Century Fox, Sony Pictures Home Entertainment, Universal Pictures, and Warner Bros. Home Entertainment Group. Once downloaded, the movies can be viewed offline on Windows-based PCs and “compatible portable devices.” AOL did not specify a file format, but it is all but certain that the company will use Microsoft’s Windows Media format. AOL becomes the fourth major digital movie store, after Movielink, CinemaNow and Guba. Apple has been long-rumored to launch a large online movie store this year.
