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.
