Perminute yes. The cost of producing all music ever has probably been higher than all movies ever just because of volume. TV is less clear would be interesting to see the numbers.

I'm not sure why total volume really matters that much. A more relevant metric would be production cost compared to sale price. A music album costs about $15 at the most, and I would imagine that the biggest pop records only cost a few million dollars at the most. A new movie costs around the same, but a few million dollars is very cheap for a movie with a wide release. Of course, I could just be way off on my estimates of producing a major pop music album.
