I mentioned recently that Amazon might be going into the video download business. Now it’s made its move with a service called Amazon Unbox. Dave Taylor does a good walk-through of the service.

Amazon is becoming the hub for both digital and paper media, and as Robert Scoble mentions, it is pushing out innovations as fast as Google does. If anyone is in a strong position to make links across the divide between paper and digital, it’s Seattle’s biggest books store.
