P2P Porn
Definition
Peer to peer porn is erotic and sexual material made by and for peers.
History
There's a long history of amateur porn on the internet. In fact, it may have a longer history that professional porn.
Before modern bandwidth capacity, people would share erotic stories and ASCII based images on BBoards and Usenet. Later, as bandwidth increased, people started sharing pictures. Often, these were scans of magazine photos.
The high costs of scanners, software and hardware for photo/video editing, and bandwidth made it challenging for people without professional equipment to create.
Enclosure of Porn
The twentieth century with its rise of corporate industrialism, saw with it an enclosure of porn and erotica.
The encompanying cultural enclosure eventually lead to the Hays Code. The Hays Code, the predecessor to the moderb MPAA, censored film, including nudity. Pre-Hays Code (enforcement) had films with nudity and, including peep shows showing beastiality.
The nineteeth century had a great circulation of cheap erotic "pamplets", through small shops stands. They operated similarly to the "head shops" of today.
Modern Developments
With recent bandwidth, camera, hardware and software developments, pornography is increasingly being made by more people.
Websites, specialist and generalist, list "amateur" or peer porn along side "professional" porn.
Unsimulated Sex in Media
A trend in the indie movie field, is blurring the line between porn and mainstream film, through unsimulated sex.
This is also the case in online video. Outside of YouTube's culturally restrictive censoring system, independent life vloggers include sexual content of their individual sites.
Future
Peer porn is often made for recognition from the peer community. That allows the coverage of fetishes not normally served through the neoliberal porn system. This implicitly can defy cultural notions of what is sexual and erotic.
