The new documentary Downloaded tells the story of Napster, the file-sharing service that ushered in a new era of digital music. Launched in 1999 by a group of friends that met on the Internet, Napster grew to 20 million users -- many of them living on college campuses -- before being shut down by a court order in 2001. Before he traveled to South by Southwest to premiere Downloaded, director Alex Winter (who starred with Keanu Reeves in the Bill & Ted's Excellent Adventure films) joined John Schaefer to talk about Shawn Fanning, Sean Parker and Napster's other co-founders.
