Hi Dave, I think if it is video over HTTP, it is counted as web media. But I am not sure how they did it. Maybe they just decided for a few web sites that provide video that all their traffic is web media. What I am more concerned about is really where rtsp stands. I have no feeling for how common it still is today. Cheers, Silvia.
