You know, I was thinking about this...a regular purchaser of porn was telling me that he liked TGP's better because TGP/MGP give you a bunch of pics/vids of the same scene. My guess is that it's usually enough to "finish" which is what the customer wants afterall. While tube sites have a huge amount of content, it seems that they do not usually have all of the videos in a specific set in the same place, so you may get one or two clips from a specific scene. maybe this drives the customer to purchase to get the entire scene and "finish". Just a thought. There may be some truth to it.
