DESCRIPTION:BitTorrent is the most popular P2P content delivery applicatio
 n where individual users share various type of content with tens of thousa
 nds of other users. The growing popularity of BitTorrent is primarily due 
 to the availability of valuable content without any cost for the consumers
 . However\, apart from required resources\, publishing (sharing) valuable 
 (and often copyrighted) content has serious legal implications for user wh
 o publish the material (or publishers). This raises a question that whethe
 r (at least major) content publishers behave in an altruistic fashion or h
 ave other incentives such as financial. In this study\, we identify the co
 ntent publishers of more than 55k torrents in 2 major BitTorrent portals a
 nd examine their behavior. We demonstrate that a small fraction of publish
 ers are responsible for 66% of published content and 75% of the downloads.
  Our investigations reveal that these major publishers respond to two diff
 erent profiles. On one hand\, antipiracy agencies and malicious publishers
  publish a large amount of fake files to protect copyrighted content and s
 pread malware respectively. On the other hand\, content publishing in BitT
 orrent is largely driven by companies with financial incentive. Therefore\
 , if these companies lose their interest or are unable to publish content\
 , BitTorrent traffic/portals may disappear or at least their associated tr
 affic will significantly reduce.\n\nThe work is based on the paper in CoNe
 xt 2010.\n\nRuben’s home page: http://www.it.uc3m.es/rcuevas\n
