Most employers have distinct policies against the accessing of any kind of online pornographic material from company computers, in addition to which some have also installed comprehensive filters and logging software in their local computer networks. One area of internet pornography that has been the target of the strongest efforts at curtailment is child pornography. Because of this, most internet pornography websites based in the U.S. have a notice on their front page that they comply with 18 USC Section 2257, which requires the keeping of records regarding the age of the people depicted in photographs, along with displaying the Name of the company record keeper.

The production of child pornography has become very profitable, bringing in several billion dollars a year, and is no longer limited to pedophiles. Philip Jenkins notes that there is "overwhelming evidence that [child pornography] is all but impossible to obtain through nonelectronic means." In 2006, the International Centre for Missing & Exploited Children (ICMEC) published a report of findings on the presence of child pornography legislation in the then-184 INTERPOL member countries. It later updated this information, in subsequent editions, to include 196 UN member countries. The report, entitled “Child Pornography: Model Legislation & Global Review,” assesses whether national legislation: (1) exists with specific regard to child pornography; (2) provides a definition of child pornography; (3) expressly criminalizes computer-facilitated offenses; (4) criminalizes the
