For all the hype about NBC's unprecedented online video coverage of the Olympics, and the massive ratings they have seen so far, there is one major demographic slipping through the cracks.

According to a MediaLife story, fewer girls aged 12 to 17 are tuning in to the 2008 Olympics than tuned in to the 2004 Olympics in Athens.

While overall viewership is up 14 percent from Athens, rating for teenage and tween girls fell 11 percent. It's an interesting point to note for advertisers attempting to reach this choice demographic.
