Turntable.fm was a social media website that allowed users to interactively share music. The website was run by Billy Chasen, who started it in January 2011 using revenue generated by his previous start-up to fund Turntable.fm. The service allowed users to create "rooms," which other users could join. Designated users, so-called "DJs," chose songs to be played to everyone in that room, while all users were able to talk with one another through a text interface. The service opened to the public in May 2011, and by late June had already reached 140,000 active users. The company used the Digital Millennium Copyright Act to license the music that was played on the website; because of this, only individuals from the United States were allowed to use the service.
