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.Children born in the 1980s onward are also the first to grow up in a world where they have access to the Internet beginning in their teenage years, and this early exposure and access to Internet pornography may be the primary driver of the increase.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.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.
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.
Some free websites primarily serve as portals by keeping up-to-date indexes of these smaller sampler sites.
These intents to create directories about adult content and websites were followed by the creation of adult wikis where the user can contribute their knowledge and recommend quality resources and links.
These files could then be downloaded and then reassembled before being decoded back to an image.
Automated software such as Aub (Assemble Usenet Binaries) allowed the automatic download and assembly of the images from a newsgroup.
The most common form of adult content is a categorized list (more often it's a table) of small pictures (called "thumbnails") linked to galleries.
