A post on The Next Web reminds us that the CD was thirty years old this month. As the story explains, the work began in the 1970s, Philips and Sony both in optical recording medium of music, leading to a common standard published in 1982. The key attribute of the compact disc is not so much their size - even if it was the most obvious difference vinyl before - but the fact that the music stored in digital form, rather than analog.

At that time, it probably seemed like a technicality to most people, but had two important consequences. Firstly, began the transition from a world of analog musical recordings - LPs and cassettes - which was digital. And second, created the precondition for the emergence of file sharing in the 1990s after MP3 compression technology has been developed, and the internet was available for general users - especially the younger ones. Services such as Napster would not have been as popular if it was not convenient digital files on CD sitting there waiting to be ripped, downloaded and shared. And why it was so easy to do because the CD came without any protective mechanism against copying whatsoever.

So how the hell did Philips, Sony and music industry what should appear, in retrospect, a big mistake? Why not worry about people copying files from the CD New? The answer is very simple: because when the CD came out, there was nothing I could copy a CD.

A year after the appearance of the CD business, IBM launched its first PC version had an internal hard drive, the IBM PC XT. Your ability? A spacious 10 MB. The CD contains about 700 MB, which means that the songs uncompressed generally require about 50 MB of storage each. The cost of any hard drive can store even a single song became so great at that time, the idea that digital piracy is patently absurd, as it would have been much cheaper to buy another copy of the CD to a hard disk for storing successively.



But what has been overlooked and dramatic reduction of the constant price per MB of hard disk space that will be held in the coming decades. Today, we have reached a point where you can buy a 1 TB hard drive for about $ 80, which means that the cost to store the contents of an entire CD in MP3 format is about $ 0,005 - and continues to decline.
The CD is a wonderful symbol of the failure of the music industry to see deeper, underlying trends in technology, and where it would lead. At the time, this meant that no one was worried about the idea that people copy and digital files from CD because they forgot that technology would make possible tomorrow what seems impossible today. This now means that the copyright industries are still trying to preserve unsustainable business models of the twentieth century rather than planning technologies have incredible than 10 times 20 or even 30 years. Just look at the history of CD and digital piracy to see how far it can go - and how wrong our assumptions may be present.
