Original article from Wikipedia seems to be too long for "Psychology wiki".
Maybe we should copy a brief definition from http://en.wikipedia.org/wiki/Portal:Pornography
"The depiction of erotic behavior (as in pictures or writing) intended to cause sexual excitement is known as Pornography. This has become a multibillion dollar industry. Ninety-five percent of the world's population has been exposed to pornography. Examples of pornographic materials include adult videos, magazines, live shows, phone sex, cable/pay per view, selected internet sites, art, etc."
