Around this time frame, pornography was also distributed via pornographic Bulletin Board Systems such as Rusty n Edie's.These BBSes could charge users for access, leading to the first commercial online pornography.Sites containing thumbs that lead to galleries with video content are called MGP (Movie Gallery Post).The main benefit of TGP/MGP is that the surfer can get a first impression of the content provided by a gallery without actually visiting it. Linklists unlike TGP/MGP sites do not display a huge amount of pictures.When a user purchases a subscription to a commercial site after clicking through from a free thumbnail gallery site, the commercial site makes a payment to the owner of the free site.
These are free websites that post links to commercial sites, providing a sampling of the commercial site in the form of thumbnail images, or in the form of Free Hosted Galleriessamplings of full-sized content provided and hosted by the commercial sites to promote their site.
The most abusive form of TGP is the so-called CJ (abbreviation for circlejerk), that contains links that mislead the surfer to sites he or she actually didn't wish to see. A linklist is a (frequently) categorised web list of links to so called "freesites*", but unlike TGPs, links are provided in a form of text, not thumbs.
It's still a question which form is more descriptive to a surfer, but many webmasters cite a trend that thumbs are much more productive, and simplify searching.
This type of distribution was generally free (apart from fees for Internet access), and provided a great deal of anonymity.
The anonymity made it safe and easy to ignore copyright restrictions, as well as protecting the identity of uploaders and downloaders.
