Last year I wrote about the future of music in a world where reproduction (copying) of music costs virtually nothing. The old model was that the publisher controlled the means of reproduction and artists made their living by promoting the sales of their recorded product for the publisher. Now that copying is free, the publisher has lost control. Artist are moving to a new mode where they give their music away to promote themselves and make their living through selling tickets live performances.
Now a Princeton University economist has come out saying the same thing. Of course, being an economist, he has numbers to back up his argument. But remember you read it here first.
