If Amazon succeeds in negotiating such a service with publishers and authors, which is still a big "if" at this point, there is a huge opportunity for them to target readers of specific titles for products with advertisements. As long as the ads were unobtrusive to the reading process, this could represent an excellent targeting opportunity for businesses and a potential additional revenue stream for Amazon.

3. Authors and Publishers Enjoy Immediate Payment

Metrics will be instantly available as to who streamed what book. This allows both authors and publishers to capitalize on work that may have sat on a shelf unnoticed in the past, either online or off. This is a model that has worked well with Apple's iPad, which Amazon is .

4. Books Open Up to Wider Market

To obtain e-books from Amazon right now, you must go to Amazon's website, search for what you want, and download it. If Amazon's purported service does it right, you'll be able to tap an app on your smartphone or their forthcoming tablet and stream a book directly to your device. This huge simplification of the process will mean that everyone with access to a smartphone now has access to books, which could easily help Amazon tap into the larger global market for e-books.
