Apparently CD Singles are in the process of leaving this mortal turntable, for the duke box in the sky. Various retailers are removing them from sale to use the retail space for something that they can actually sell.
Maybe I missed something, but I didn't actually know that CD Singles still existed, though I know the technology was available once. When CDs launched I remember seeing singles, as oddities that they tried to sell cheap, full length CDs were - and still are - too expensive. I never bought a CD single, I've only ever bought full length CDs, I thought that singles had been such a failure that they had been withdrawn a decade ago!
Apparently this death is the result of evil cyber-pirates stealing the songs from the poor record companies, and giving it away to the rich consumers in the form of MP3s.
I'm not in favour of theft or unlicensed duplication, but I don't think the odd CD duplicated or the odd MP3/Ogg is a worry. Rather the massive factories churning out millions of counterfeit CDs and DVDs outside the reach of the law, is a bit more of a problem. If real CDs and DVDs were cheaper, then most people wouldn't bother copying them or buying counterfeit versions, they'd just buy the real thing, because it's easier.....
