The Attorney General's Commission on Pornography determined that the largest consumer group of pornography was boys aged 12-17. This was back in the mid-1980s, before the Internet. Back then boys most likely encountered pornography in magazines at a friend's house or in the trash, or on late-night cable TV.
While those are still dangers, parents today need to be aware that pornography is available to virtually every form of multi-media and communications technology. Porn is easily accessible on the Internet, but many parents don't realize how many ways kids have to access the Internet. In addition to computers, porn can be accessed through cell phones, PDAs, portable video games, and iPods. In addition, pornographers target children through e-mail spam and spyware on music and video game sites popular with teens.
