This was a revolutionary way to download files. It was fast, it had the songs you wanted, and people could chat with one another. At Napster’s peak there were 80 million users. This file sharing boom wouldn’t come without a cost though. Napster officially started in June of 1999, and not even one year later, in December of that same year, the RIAA (The Recording Industry Association of America) sued Napster for copyright infringement, and by February of 2000 tons of Universities had banned the usage of Napster from their schools. Napster tried to negotiate, but to no avail. In April of 2000 the rock band Metallica sued Napster for copyright infringement. Napster showed concern and removed over 300,000 Napster users from the service who were downloading Metallica songs. Napster went to court throughout the year, each time making slight changes to the Napster service to help filter out copyrighted songs. They had eventually screened out 99% of all copyrighted songs, but a district court judge said Napster couldn’t enable file sharing again until they screened out 100%, and thus, shut down the Napster Service.
