A9's Low Popularity & Slower Growth

NetRatings sent out some Amazon stats in advance of their earnings report. Interesting to me was a breakout on A9. It shows growth from the fourth quarter of 2004 to the same period of 2005. However, growth from the third to the fourth quarter of 2005 is nowhere near as much as Amazon itself or the Amazon-owned Internet Movie Database. Traffic to both those sites is much higher than A9:
