The story

On 1 February 2001 MediaSentry was founded by Aaron Fessler in Morristown, New Jersey.

On 13 June 2005 MediaSentry was acquired by SafeNet. SafeNet sold the MediaSentry division to Artistdirect in April 2009.

In late 2007 the University of Oregon, represented by Oregon Attorney General Hardy Myers, refused to provide information on its students to the RIAA, questioning the tactics used by MediaSentry in one of its investigations. The next year Central Michigan University accused MediaSentry of violating its students' privacy after the company ignored a ruling that it was illegally operating without a private investigator's license.

In January 2009 the RIAA canceled their usage of MediaSentry for undisclosed reasons.

In August 2009, ARTISTdirect restructured MediaDefender and MediaSentry, creating Peer Media Technologies.
