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.One recent entry into the free pornography website market are Thumbnail gallery post sites.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 Galleries—samplings of full-sized content provided and hosted by the commercial sites to promote their site.A 2015 study finds "a big jump" in pornography viewing over the past few decades, with the largest increase occurring between people born in the 1970s and those born in the 1980s.While the study's authors note this increase is "smaller than conventional wisdom might predict," it's still quite significant.There was a rapid growth in the number of posts in the early 1990s but image quality was restricted by the size of files that could be posted.The method was also used to disseminate pornographic images, which were usually scanned from adult magazines.
Pornographic images had been transmitted over the Internet as ASCII porn but to send images over network needed computers with graphics capability and also higher network bandwidth.
One of the early Gopher/FTP sites was at tudelft and was called the Digital Archive on the 17th Floor (List of websites founded before 1995).
This small image archive contained some low quality scanned pornographic images that were initially available to anyone anonymously, but the site soon became restricted to Netherlands only access.
On the Web, there are both commercial and free pornography sites.
The bandwidth usage of a pornography site is relatively high, and the income a free site can earn through advertising may not be sufficient to cover the costs of that bandwidth.
Around this time frame, pornography was also distributed via pornographic Bulletin Board Systems such as Rusty n Edie's.
