The BBC News website has an excellent Q&A article up at the moment dealing with the implications of DRM infested music files in the wake of the closure of Virgin Digital. In case you've not heard about this yet, Virgin Digital is closing its doors which means that any Club subscribers will now have hard drives full of media content that they can no longer play.
The article points out that we've "... been here before, most notably with the video wars between VHS and Betamax. When Sony's Betamax format lost the battle, Sony threw in the towel and started making VHS recorders instead, leaving Betamax fans reliant on aging machines."
All perfectly true, except when Sony threw in the towel with Betamax, they didn't instantly invalidate any media content that had been stored on Betamax tapes - which is precisely what's happening here.
I feel very sorry for any Virgin Digital subscribers that have been affected by this fiasco, but hopefully they'll start telling their friends to avoid DRM infested music in future and the music industry will stop treating their loyal customers as criminals.
