New media companies continue to have a hard time managing piracy, also known as, digital theft. While file sharing and peer to peer file sharing would factor in to digital theft since is one of the means of piracy, not all file sharing and peer to peer filing would be considered illegal activity. For background, file sharing is the act of transferring files from one computer to another. Peer to peer file sharing (aka P2P file sharing) allows someone to access things such as music, movies, or book using a P2P software. For example, Amazon allows you to loan someone a book from your library which is totally legal.
Hollywood is still fighting the piracy battle. Brad Stone and Brian Stilter wrote an article that appeared in the New York Times, titled, "Digital Pirates Winning Battle With Studios" that covered the enormous efforts the makers of the move Dark Knights made with the creation of a anti piracy campaign that failed. The movie was illegal reproduced despite all of their efforts.
