1、 Steve JobsFebruary 6, 2007With the stunning global success of Apples iPod music player and iTunes online music store, some have called for Apple to “open” the digital rights management (DRM) system that Apple uses to protect its music against theft, so that music purchased from iTunes can be played
2、 on digital devices purchased from other companies, and protected music purchased from other online music stores can play on iPods. Lets examine the current situation and how we got here, then look at three possible alternatives for the future.To begin, it is useful to remember that all iPods play m
3、usic that is free of any DRM and encoded in “open” licensable formats such as MP3 and AAC. iPod users can and do acquire their music from many sources, including CDs they own. Music on CDs can be easily imported into the freely-downloadable iTunes jukebox software which runs on both Macs and Windows
4、 PCs, and is automatically encoded into the open AAC or MP3 formats without any DRM. This music can be played on iPods or any other music players that play these open formats.The rub comes from the music Apple sells on its online iTunes Store. Since Apple does not own or control any music itself, it
5、 must license the rights to distribute music from others, primarily the “big four” music companies: Universal, Sony BMG, Warner and EMI. These four companies control the distribution of over 70% of the worlds music. When Apple approached these companies to license their music to distribute legally o
6、ver the Internet, they were extremely cautious and required Apple to protect their music from being illegally copied. The solution was to create a DRM system, which envelopes each song purchased from the iTunes store in special and secret software so that it cannot be played on unauthorized devices.
7、Apple was able to negotiate landmark usage rights at the time, which include allowing users to play their DRM protected music on up to 5 computers and on an unlimited number of iPods. Obtaining such rights from the music companies was unprecedented at the time, and even today is unmatched by most ot
8、her digital music services. However, a key provision of our agreements with the music companies is that if our DRM system is compromised and their music becomes playable on unauthorized devices, we have only a small number of weeks to fix the problem or they can withdraw their entire music catalog f
9、rom our iTunes store.To prevent illegal copies, DRM systems must allow only authorized devices to play the protected music. If a copy of a DRM protected song is posted on the Internet, it should not be able to play on a downloaders computer or portable music device. To achieve this, a DRM system emp
10、loys secrets. There is no theory of protecting content other than keeping secrets. In other words, even if one uses the most sophisticated cryptographic locks to protect the actual music, one must still “hide” the keys which unlock the music on the users computer or portable music player. No one has
11、 ever implemented a DRM system that does not depend on such secrets for its operation.The problem, of course, is that there are many smart people in the world, some with a lot of time on their hands, who love to discover such secrets and publish a way for everyone to get free (and stolen) music. The
12、y are often successful in doing just that, so any company trying to protect content using a DRM must frequently update it with new and harder to discover secrets. It is a cat-and-mouse game. Apples DRM system is called FairPlay. While we have had a few breaches in FairPlay, we have been able to succ
13、essfully repair them through updating the iTunes store software, the iTunes jukebox software and software in the iPods themselves. So far we have met our commitments to the music companies to protect their music, and we have given users the most liberal usage rights available in the industry for leg
14、ally downloaded music.With this background, lets now explore three different alternatives for the future.The first alternative is to continue on the current course, with each manufacturer competing freely with their own “top to bottom” proprietary systems for selling, playing and protecting music. I
15、t is a very competitive market, with major global companies making large investments to develop new music players and online music stores. Apple, Microsoft and Sony all compete with proprietary systems. Music purchased from Microsofts Zune store will only play on Zune players; music purchased from S
16、onys Connect store will only play on Sonys players; and music purchased from Apples iTunes store will only play on iPods. This is the current state of affairs in the industry, and customers are being well served with a continuing stream of innovative products and a wide variety of choices.Some have
17、argued that once a consumer purchases a body of music from one of the proprietary music stores, they are forever locked into only using music players from that one company. Or, if they buy a specific player, they are locked into buying music only from that companys music store. Is this true? Lets lo
18、ok at the data for iPods and the iTunes store they are the industrys most popular products and we have accurate data for them. Through the end of 2006, customers purchased a total of 90 million iPods and 2 billion songs from the iTunes store. On average, thats 22 songs purchased from the iTunes stor
