Napster

 Napster

What: A peer-to-peer file sharing service that allowed people to share MP3s

When: 1999-2001

Why: The sharing of music was illegal under copyright.  Many musicians and companies took legal action

Metallica: Were the most famous/vocal of those rallying against it.  They had an unreleased, demo version of a song leaked on to it and then played on radio stations.

Spotify: This sharing of music took it thoroughly out of the physical realm and into the digital.  It was clear that people wanted to have access to music on a large scale. It inspired Spotify, which is well known for paying artists next to nothing for streams.
