It’s been a long time coming, but Amazon is finally upgrading its Video on Demand service to include high definition content from major studios and broadcasters. More than 500 HD movies and TV shows will be available initially, in addition to the 40,000 it already has in standard definition, which will be accessible not only through a computer but also on compatible standalone devices.

This includes the Roku digital player box, TiVo Series3, TiVo HD and TiVo HD XL DVRs, Sony televisions connected to the company’s Bravia Internet Video Link device, and Panasonic Viera Cast-enabled HDTVs. Amazon users can rent HD movies for $3.99 to $4.99 apiece or purchase TV shows in high-def for $2.99. At least for now, Amazon is not selling HD movies – though standard definition titles are available for around $14.99.
