MediaDefender, Inc. (now Peer Media Technologies) was a company that fought copyright infringement[1] that offered services designed to prevent alleged copyright infringement using peer-to-peer distribution. They used unusual tactics such as flooding peer-to-peer networks with decoy files that tie up users' computers and bandwidth.[2] MediaDefender was based in Los Angeles, California in the United States. As of March 2007, the company had approximately 60 employees[3] and used 2,000 servers hosted in California with contracts for 9 Gbit/s of bandwidth.[3]
These types of organizations are being hired to attempt to stymie peer-to-peer (P2P) traders through a variety of methods including posting fake files online and recording individuals who contribute copyrighted material, but also marketing to individuals using P2P networks.[4]
