A&M Records Inc. v. Napster Inc.
During the early 2000s, music fans freely shared their favorite songs online. Every day, they went to Napster and other peer-to-peer music sharing services to exchange thousands and thousands of MP3 files. They had access to almost every type of music and artist. There was just one problem. No one was paying for anything. Musicians, songwriters, producers, and record companies were losing millions of dollars.

So A&M Records and other companies affiliated with the Recording Industry Association of America filed a lawsuit against Napster and its creator Shawn Fanning. (Fanning was a college student at Northeastern University when he began the file-sharing service in 1999.) The suit accused Napster of contributory and vicarious copyright infringement. The case landed in the United States Court of Appeals for the Ninth Circuit. There, Napster was found guilty on both counts, and the site was forced to shut down in 2002. Several years later, a similar file-sharing service known as Grokster also had to cease operations when the Supreme Court ruled against it in MGM v. Grokster.
