If a scene from the past was regarded as particularly brilliant, then the best way to revive it would be for the scene to be re-made with current models and producers, just as Hollywood re-makes its best films for new generations of audience.
Uhh...no. I'm going to agree with Noise on this one - the simple fact is that certain things aren't going to be as good the second time, and moreover, in a way it's somewhat rude to the original actresses I would think to just say "oh, we're writing you out and casting someone else as you". Imagine if someone for instance went back to all the videos with Paris Kennedy from PFG, and remade them with Kym (from the "newer" videos) instead. It would be kind of like a slap in the face.
That, and I don't think anyone would ever be able to recreate the best pie sandwich ever from Heather VS Paris =P
As for messydom's ideas on a sort of "past videos" annex, I agree that there should be some way to acquire some of these older videos. Even dis-counting the places that closed down from not wanting to publish anymore, there are still easily dozens of other videos to be had, and collecting them for either free or low cost re-release would be great for people seeking them. (In my case, I'd love to get ahold of the Dunk Tank Divas videos from Wamtec - they were some of the earlier videos to actually have nudity in the dunk tank, and I swear since then it's like everyone panicked about having too much sexual content or something, because we're only just recently having ONE dunk tank company starting to do nude scenes again, Dunktankbabes).
While I agree with the notion that too much free content diminishes if someone would spend money on a newer title, I also disagree with it in the same thought: I would think that seeing a few OLDER videos and their quality would make me more likely to shell out cash for newer releases if they hold my interest. In the case of Messygirl for instance, if you have a membership (which I did), you have access to a rather large collection of clips and various video releases, and several of the older clips with Linda and Sara and other now-gone models ended up being the basis for my purchases of newer videos. I suppose it differs from person to person though.
