The music business has changed dramatically in the last couple of decades since the massive expansion of the internet, the development of music file compression algorithms, and the concept of anonymous file-sharing services. The business has perhaps been slow to respond to the technological change having attempted, often through the law, to try and stem the tide of illicit file sharing with scant regard for the fact that those who use such systems to obtain digital goods, such as music, are now entrenched and rather reluctant to go back to the old model of paying for those goods.
