NBC to offer free episode downloads

Is NBC's digital distribution strategy clear to anyone out there. Shows are available on Amazon Unbox, Hulu, and now on NBC Direct. Where does the user end up, hard to tell. What drives them to one of these sites. Also hard to tell. How does the consumer find out that the episode is free with commercials on one distribution platform, and available for permanent ownership on another. Beats me. Why did they create Hula in the first place and when we they end that partnership with Fox. (I'm guessing it closes in a year.) We are watching NBC go through a great big learning curve. And it will be interesting to see what they do next.
