Operation Avalanche was a major United States investigation of child pornography on the Internet launched in 1999 after the arrest and conviction of Thomas and Janice Reedy, who operated an Internet pornography business called Landslide Productions in Fort Worth, Texas. It was made public in early August 2001 at the end of Operation Avalanche that 100 arrests were made out of 144 suspects. It was followed by Operation Ore in the United Kingdom, Operation Snowball in Canada, in Germany, Operation Amethyst in Ireland and in Switzerland.
