In the late 1990s, individuals with a personal computer and access to the Internet, using a program called Napster, began to offer free digital copies of copyrighted sound recordings for download by other users. Although the recording companies and music publishers were successful in obtaining an injunction against Napster for copyright infringement, millions of individuals in the United States and overseas continued to share digital files of copyrighted recordings using a subsequent generation of file-sharing computer programs...Since September 2003, the recording industry has filed more than 18,000 lawsuits against individuals, claiming billions of dollars in damages based on P2P file sharing and consequent violations of federal copyright laws..
