Jukebox in the sky, or in our hands?

HD vs year

Further to our discussion of streaming vs downloading a couple of weeks ago, here’s a short article from Digital Renaissance, “The Future of Private Copying,” that came out about a year ago, in which the author gives projections for the average size of a hard drive. I’ve taken the data from that article* and plotted it; note that it’s a straight line on a semi-logarithmic scale (that is, the size of hard drives is increasing exponentially, Kryder’s Law). Also note that the average song is about 5 MB (0.005 GB) as an MP3 and about 25 MB in a lossless format. As the author writes, “How will this development affect private copying? When music fans can say: “I have all the music from 1950-2010, do you want to copy?” What kind of business models will be viable in such a reality?”

I’d love to see something similar forecasting the use of the wireless spectrum, which I know is a bit up in the air right now because of the delays in switching from analog to digital television broadcasts. If anyone can point me to a good reference, I’d really appreciate it.

*I haven’t sourced the data, but a quick troll through Dell and Apple’s site suggests that the numbers are in the right ballpark, and the shape of the curve is documented. It is an extrapolation though, which is always a bit dangerous.

The spectrum is there. It all depends on regulation and deployment costs in a country like the US. For instance, in Korea, SK Telecom has had MelOn, a streaming music service, since 2004. AFAIK, you can subscribe and stream all you want to your phone….

I would say that storage is free, bandwidth is where you pay. And you end up paying the provider of said bandwidth plus the fees to cover the licensing of the material. Since in the US, the copyright complexities and general craziness of the recording industry, and the propriety-stuff-first thinking of the wireless carriers, it becomes orders of magnitude harder. But only from a business perspective. This is all easy from a technology standpoint, and really, advantageous from a cost perspective.
