If you were in any doubt of the enclosure-acts-like enabling power of rights technology, or the jeremiads of Cory Doctorow et al, then pay attention to what Andrew just pointed out:
“So has no one else pointed out that until today, all those Music Videos in the iTunes store were free to watch? That kind of sucks, no?”

No, they weren’t. While there were a selection of music videos in the store that were free to watch (and I do miss their passing), it didn’t have anywhere near the range of the ones that are available now. Certainly a lot of major artists never had any videos there.
As someone who works for one of the majors (Sony BMG) on digitizing the entire catalog for the company, I can tell you that we never bothered to digitize our library and encode to high-end format that Apple is offering (h.264). But now that AOL, Yahoo and Apple have begun offering a higher-end service, we’ve digitized more than 7000 videos (we only had a handful before, all done in lowend codecs, streamed primarily).
Even if videos turn out to be a lousy business, we have now digitized the entire catalog that we didnt have before. We have it at 25 MB/sec. too.
