Porn sites are responsible for the latest revolution in the industry of pornography, since the popularization of the videocassette and porn video stores. Thanks to porn sites, anyone is able to access pornographic content from anywhere having an internet connection and most important, anonymously. The possibility of anonymous access to porn was something near to impossible until the popularization of the internet and it’s no surprise that one of the first uses of the web was to trade naughty pictures among users.

In the beginning, porn content was restricted to Usenet groups, until pages and connections become good enough to organize content in websites (porn content is heavy, since its composed mostly by pictures and video files). Then, all porn sites were free, and all users had free access to any pornographic content. Later, webmasters started to realize that most people would pay to see porn if that was the only option. Commercial websites had to offer something more to the users, such as more hardcore pictures or special videos. Today, the vast majority of porn sites are paid and the few free sites still survive thanks to advertising of other products such as sex toys or even other paid porn sites.

Currently, porn sites comprise the largest part of the internet content. Porn sites are so common that one of the biggest issues of the computer world today is to find a way to limit such content. Several attempts have been made to avoid and restrict the access of porn sites by children and people in countries where pornography is forbidden by cultural or religious issues. There is also the problem of child pornography in which the internet also plays a major role. Police is fighting fire with fire by using the internet to find child pornographers. The larger the bandwidth of porn sites become, more content they are able to comprise.
