Comment The answer? END COPYRIGHT (Score 1) 417
Not in one step. First we halve the time to termination of copyright on all new and existing copyright material. If after a year that wasn't too traumatic, halve it again. And so on.
I'm pretty sure artists will keep producing. Movies will still be made. (there does not seem to be a high correlation between cost and financial success in the movie business. And anyhow, a large part of profits seems to come from theatre showings).
