Why doesn't YouTube/Google Video post full videos?

I was curious.

I don’t understand why YouTube doesn’t post full videos (i.e. videos that are 1–2 hours long.) It’s often frustrating when you have to hunt and peck to find the “next installment” and the “next one after that”. For most music vids, that’s fine. (I don’t watch those). I am talking about documentaries and shows like that. It’s watch the first nine minutes, then the next 7.58 minutes and then the next 11 minutes, etc etc.

At one point, I remember watching a few videos on Google that were longer (1–2 hours). Now, I go on Google and all they have is “YouTube” videos (!)...once again, sliced up in segments.

Does anyone know why this is done? Andy ideas if this will ever change?

I wish they had full shows.
