Most people think of the Internet as an innovation that allows them to stay in touch with friends, access information and stay entertained for hours. Sadly, there are also thousands of people across the country who use this technology for a more sinister purpose—trading child pornography.

It's estimated that more than 5 million pornographic pictures and videos of children are circulated on the Internet every day. "Part of the reason for this show is for us to be educated about what the word pornography really means," Oprah says.

To help Americans understand the severity of the problem, Lisa Ling travels to Milton, Florida, to document the arrest of a suspected child pornographer.
