Amazon really has diversified since it first started selling books in 1995. It's one the internet's biggest brands and has begun leveraging this recognition by offering video on demand.

Amazon Unbox, as it's called, will have movies and television shows available for download and playback in Amazon's own media player. You can choose to rent or buy the videos. Rented videos will be time limited.

You will need a speedy broadband connection as an hour of playback will take up 1GB but you can watch films as they're downloading. The files are in wmv format with an accompanying .amaz file for copyright protection. The Unbox player is not compatible with the Apple's operating system.

Videos may be transferred to protable media players that are Plays for Sure compatible.
