While pornography has been present throughout human history in various forms, such as ancient erotic art to more modernized motion pictures, research shows an increase in use over recent decades given the rise of technology and accessibility.

Pornography, meaning any media intended to depict or describe sexual content to heighten sexual arousal or pleasure, can serve many purposes. Users may seek sexual pleasure, find it a fun way to fight boredom, or turn to it because they are down or stressed and perhaps want to escape their feelings.
