Say Goodbye to Amazon Unbox. Say Hello to Amazon Video On Demand. Launched on Wednesday, this new video streaming service does as it drab name says; it offers streaming, ad-free video on demand. PC owners can stop taunting their OS X friends as the new Video On Demand service is compatible with Macs (finally!). If you own a Tivo, a Windows Media Center extender box (can we say Xbox360 instead?) or a Sony Bravia Internet Video Link TV, you can join the streaming party, too. While not as slick as Hulu (or free for that matter), the Amazon interface is functional with all the typical controls to control playback and view in fullscreen mode. It offers Amazon’s entire catalog of 40,000 movies and TV show which exceeds Hulu and Netflix in sheer volume of content. Movie rentals are $2.99 to $3.99 while TV rentals are $1.99 and expire 24 hours after purchase. With a free 2 minute preview available for all videos, you can at least try before you buy. Overall, we must say that Video on Demand is a respectable attempt at streaming video. Enjoy the Hoopla while you can, though, as you, Amazon, may be upstaged September 9th.
