It happened to the record industry first. While popular music had long been available on radio, it could be argued that a true music industry as we know it today didn’t arise until the 50‘s and 60‘s when distributable media and players became widely available. To summarize – you bought your music on record, then on 8-track, then on cassette, and then on CD once again. Sounds very much like a ‘cartel’, or “association of suppliers with the purpose of maintaining prices at a high level and restricting competition”. Record companies (not artists generally) held the content and the means of distributing it to us the passive consumer.
But that’s where technology turned. CD drives in computers plus early sharing software like Napster meant that instead of getting good at mashing the pause button on your stereo so recording to cassette stopped before the adds kicked in, you could rip a whole CD to MP3 in minutes and upload it for anyone who was also connected to the net. You could also bypass the record stores entirely by downloading songs, for free. It meant you didn’t have to buy your music a fourth time in some other format – you now controlled the file. No it wasn’t legal, but it was what the people wanted.
