Shawn Fanning, John Fanning, Sean Parker, 1998
Napster has often been called the fastest-growing business in history. It was co-founded in 1998 by Shawn Fanning, his nephew John Fanning and Sean Parker as an independent peer-to-peer file-sharing service. Napster was named after Shawn Fanning’s nickname, which he got for his nappy hair under his baseball cap. Within a year the service had ten million users. Napster allowed them to easily share MP3 files with each other. In 1999 the company was sued by metal band Metallica for copyright violations. But because of the huge publicity, Napster grew even bigger. In 2011 Rhapsody acquired Napster and restructured it completely.
