The first in the series aired in November 2004 as a Dateline NBC segment called Dangerous Web. The operation was set up in a home in Long Island, NY, to which 18 men came over two-and-a-half days after making an appointment for sex with a minor. One of the men in the investigation was a New York City firefighter, who was later fired by the FDNY.

Predators scouring the Internet, targeting children for sex: It's a national problem that Dateline has helped uncover. We got such an overwhelming response from our last investigation— some 15,000 emails from parents, grandparents, teachers and law enforcement— telling us to "keep up the good work," and "keep the issue alive." On Wednesday night, April 26, Dateline is back with the fourth undercover investigation. This time, we traveled to small town America. Even far from the big cities and suburbs, vulnerable young teens are not far from danger. A warning: some of what you're about to see is explicit.

This report airs May 17, Wednesday, 9 p.m.: This month, millions of people have been watching our investigations into computer sex predators — among them, some of the suspected predators themselves. And what's most surprising is that even knowing that they may be walking into a sting is not enough to keep some of them away. Tonight, we're back in Florida, where we started our investigation last week. We want to remind you that some of what you'll see and read is explicit.

And once again, even men who've seen our reports show up at the door. We should let you know, some of what you'll see and read below is explicit. This report first aired on NBC, Sept. 13.

It's what prompted our entire series of predator investigations: Grown men sending graphic e-mails to young teenagers. And now, it's what has forced a powerful congressman out of office in the scandal that's consuming Washington. Representative Mark Foley of Florida is accused of having sexually explicit online chats with underage teens. Dateline's latest investigation also uncovers some prominent men caught in what police say are criminal acts. They, too, risk losing their jobs... and in some cases, perhaps even their freedom. Again, we want to warn you that some of what you’re about to see is explicit. This report airs Friday, Oct. 6.
