Grooveshark, a subsidiary of Escape Media Group, is an online music streaming service based in the United States. It has a search engine, streaming service, and recommendation application. Users can stream and upload music that can be played immediately or added to a playlist. As of January 2012, Grooveshark has been sued for copyright-violations by all the major music companies, namely EMI Music Publishing, Sony Music Entertainment, Warner Music Group, and Universal Music. For one suit complaining about copyright-infringement, the liabilities have been estimated at seventeen billion U.S. dollars. Concerns about copyrights led Google, Apple and Facebook to remove Grooveshark's applications from Google Play, the App Store (iOS) and Facebook platform respectively. In response, Grooveshark has stated that it operates under a 'safe harbor' provision of U.S. law. Grooveshark is a rich Internet application that originally ran in Adobe Flash.
