To Catch a Predator

To Catch a Predator is a television program designed to catch adults trying to have sex with children below the age of 16. People were lured to meet with a decoy under the pretense of sexual contact and then confronted. Show host Chris Hansen clarified in an interview with NPR News that these subjects should be labeled as potential sexual predators, and not pedophiles. "Pedophiles have a very specific definition, people who are interested in prepubescent sex," he stated. 
The series premiered in November 2004, and featured 12 investigations in total held across the United States. The investigations were conducted as undercover sting operations with the help of on-line watchdog group Perverted-Justice. Since the third installment, law enforcement and other officials were also involved, leading to the arrests of most individuals caught. No new episodes have aired since December 2007.
NBC affiliates WTMJ in Milwaukee, KSHB in Kansas City and WBRE have also done local versions of "To Catch a Predator". Various spin-offs have aired in the same format, including "To Catch a Con Man", "To Catch an ID Thief", "To Catch a Car Thief" and "To Catch an i-Jacker", which featured iPod thieves. "To Catch a Predator" is also aired on FX and Crime &amp; Investigation Network in the United Kingdom, the Crime &amp; Investigation Network in Australia and New Zealand and FOX Crime in Portugal.
