Napster was a pioneering online platform launched in 1999 that allowed users to share and download music files for free. It utilized a peer-to-peer (P2P) network, enabling individuals to connect directly with one another to exchange songs, primarily in the MP3 format. This innovative approach quickly gained popularity, attracting millions of users and transforming how people accessed music. However, Napster faced significant legal challenges from the music industry, which argued that the service facilitated copyright infringement. In 2001, a court ruling forced Napster to shut down its file-sharing service. Despite its closure, Napster played a crucial role in shaping the future of digital music distribution.
