Zd,
If I understand you correctly,you're suggesting that the music industry hasn't made sufficient effort to market sound quality and, if they had (successfully) educated consumers on the subject, they wouldn't be "bleeding to death" (my original phrase). You're point is taken, but - in the big picture - it's hard to see how a better effort would have materially changed the fate of the major labels. Every bit of market research I've seen (and I banked the industry for decades) says that high performance (or hi-rez) formats - at best - offer only a short term sales bump.
SACD (to cite just one example) was Sony's (futile) attempt to sell high quality sound. It was generally acclaimed for performance, assailed for convenience (effectively copy protected) and ended up essentially still born. Even more successful hi-rez roll-outs like Blu-Ray (to use your video example), have proven to provide an early bumps as enthusiasts replace their collections with higher quality versions. From a small early base, rapid growth lasts a few years and then fades. Price premiums are lowered and sales plateau, then fade. That's where Blu-Ray stands today. Like other hi-rez formats, it has demonstrated a limited life span.
BTW, SACD was marketed very aggressively in Japan (where new formats are taken up at a much higher rate than in Europe or the US) and still tanked quickly.
Bottom line: Most people in the business believe that, over the long haul, only a small % of the market will pay a premium for high performance entertainment software. This may be enough to sustain a profitable boutique industry, but there's little evidence that it will support a mass market industry. Hence my original observation about shrinking record companies having little to do with SQ. There's little evidence that there are enough $ chasing SQ to support a mass market record industry that attempts to differentiate itself (from cheaper, lower quality SQ alternatives) on that basis.
BTW, the question has been studied to death. I believe that you'll continue to see proprietary hi-rez music formats (even for downloaded and/or streamed content) because the content companies will seek the short-term sales bump. In the end, I don't believe that they'll ever be viewed as a long term, mass market solution to bringing sufficient $ back to the table to revive the business.
