7.19 Music and Video Piracy
The popular practice of downloading music and video files raises several technological, business and legal issues.Music
Music downloading and swapping is very popular on the Internet. An estimated five billion songs, amounting to 38,000 years of music, were swapped on peer-to-peer websites in 2006 (i.e. largely illegally), while 509 million were purchased online. {1}. In the UK, the number of illegal music downloads was estimated to be 1.2 billion in 2010. {2} Although a 2006 study by A. Zentner concluded that file sharing contributed to only a 7.8% drop in sales, {3} music retailers have naturally tried to suppress the activity. The seamless integration of Apple's iPod and iTunes store (hardware with easy-to-use and pay-for content) greatly contributed to the popularity of both product lines, and Apple first introduced Digital Rights Management (DRM) to control the subsequent distribution of its music. Songs could be copied no more than five times, could not be played on non-Apple machines, and could not be burned in CDs more than seven times.
Nonetheless, programs to break DRM security software appeared widely on the Internet, and Apple abandoned this approach in the face of customer opposition and the appearance in 2007 of the Amazon online music store, which offered music without these restrictions (and indeed with the blessing of the big recording companies). The impecunious, particularly students, had long objected to DRM, but the contest on an industry level was between copyright owners and companies supplying the devices, software and services to carry the music, i.e. companies like Dell, Microsoft and Time Warner Cable, where the big players ultimately won.
Music is not only sold as discrete audio files to be saved on computer hard disks or mobile phone flash memories, but as streaming media. Web video, music and other large media files are broken into chunks by streaming software, sent as chunks over the Internet, and played as a continuous sequence of chunks at the client computer. Popular streaming software includes Microsoft's Media Player and Apple's QuickTime. Streamed files must be viewed 'live': they cannot be saved and copied or sold on.
Videos
Though the transmission of MP3 music files does tie up Internet resources, much more demanding are videos, where a single, high-quality film may take a whole day to download, even over broadband connections. Some 160 million Americans in August 2009, for example, watched over 25 billion videos on the Internet. YouTube accounted for 40% of this viewing, but the remainder was services from sports, news and entertainment companies. {8} The resources used were phenomenal, and called on several technologies.
Two were the file download and streaming mentioned above, but a third was what is called Peer to Peer (P2P) technology. P2P transmission operates by segmenting the file and sending the segments over a large network of computers, employing the hard disks, processing power and bandwidth allowances of hundreds and sometimes thousands of participating machines. Even otherwise idle computers are pressed into service. The most commonly used P2P net employed today is that designed by BitTorrent, which indeed carries 30-50% of all US Internet traffic. Much of that traffic consists of media files used in breach of copyright, but BitTorrent Inc itself and other companies provide legal P2P facilities, as this technology provides an efficient and scalable means of handling large files. Akamai, for instance, a major P2P network distribution supplier, maintains a network of 84,000 servers in 72 countries.
