The adult industry has been losing the stigma that has been attached to it for so long. It has become a mode of general entertainment. Porn has been existent and is probably as old as civilization itself, starting from the early erotic art of the Roman Empire.

Base reliefs on buildings and on various artifacts depicting images of copulation and other sexual acts have been excavated and serve as proof that the concept of porn is not something new. Though it is difficult to pinpoint an exact period as to when it all started, the modern understanding of porn started during the early nineteenth century, when the Victorians unearthed erotic artifacts from the ruins of Pompeii and suppressed them from being exhibited in public.

This was done in order to not allow the 'obscenities to deprave and corrupt those whose minds are open to particular immoral influences.' The established nature of the porn industry is the not the result of an unimpeded journey. However, the adult industry has battled many odds and emerged strong. The estimated net value of all forms of adult material, including those which are available online, was somewhere between $2.6 billion and $3.9 billion in the United States alone in 2001.

This industry has also been a major deciding factor in establishing the video format wars in the early 70's between Betamax and VHS, and has consequently staked its part in the Blu-ray and HD-DVD format debates.

Of course, in such a strong industry, an underground offshoot is bound to develop. As a result, we are now seeing the rise of a lot of amateur porn. Besides the usual print and video formats, the Internet has played a major role in serving this end, since practically everything is leaked and posted on the Internet and is available to almost anyone with basic browsing knowledge.

The adult industry has broken cultural taboo barriers and is challenging well established norms of the current status quo by crossing over to media which has only recently become accessible to almost any willing individual.

Nowadays, there is a movement towards various niches in the genre for adult content. Thus, there is a tendency to catering to varying audience tastes now. You may type a search word related to porn on a search website and get an exhaustive list of links featuring every variation of the sexual act, whether it is concerned with fetishes, interracial sex, sex between all combinations of sexual orientation, and various other subtypes which defy labeling.

A lot of porn has become increasingly mainstream. Now a lot of soft-porn content is available which caters to a wider variety of audiences. These depictions usually are successful in straddling legal boundaries and restrictions, provided that they comply with regulated requirements, such as keeping material which are too explicit from being obtained by minors.

Probably the best indicator that the adult industry has fully matured has been the legalization of the sex industry in countries such as Holland. Similar measures have been observed elsewhere, particularly in the United States and Europe in the form of red light districts. Even though various factions have been opposing the industry of adult content, this industry has been growing in leaps and bounds.
