DRM and Business (Make-up from last week 11/4)

As I read the conflicting arguments and engaged debates about how the entertainment industry should treat its content-- as a product or marketing tool-- I realized that the very definition of music, and film, and art, is changing. DRM is the outcome of decades of conceiving of music as a tangible product. How was music conceived of, and talked about before there was any recording technology? 

It's a little disturbing that the interests of "business" and "society" are so drastically pitted against each other. This can't last for long, if one wins the other looses-- and then the winner will consequently  loose. It seems to me that society and business could never really be that separate. Maybe we have out-sourced, vertically integrated and expanded markets to the point where business benefits from the collective loss of society, but this seems like a huge mistake in the larger scheme of things, and evolutionary fatality. Using music and film content as a marketing tool seems to placate this severely unhealthy conceptual divide between society and business interests. But I'm wondering how deep this tactic can really go at this point; we need to build business around the health of society and I'm not sure this concept will ever catch on.
