NBC selling William & Harry interview on iTunes

Matt Lauer’s highly-promoted William & Harry interview, which aired on the Today Show and Dateline NBC, is available for $1.99 on iTunes. So who would pay to download the 38-minute clip, especially when all of the video is available to watch for free on MSNBC.com? Apparently a fair number of people, as the interview is ranked #2 in the list of most popular TV shows on iTunes right now.
