Abstract-Various tools are available for increasing the speed of content dissemination such as embeddinigs in some popular web pages, sharing in some other social networks, and advertisement. In particular, when individuals pass through a content provider to distribute contents, they can benefit from tools such as recommendation systems. The content provider can give a preferential treatment to individuals who pay for advertisement. In this paper we study competition between several contents, each characterized by some given potential popularity. We study competition through advertisements that are placed at the beginning of the dissemination of contents. We answer the question of when is it worthwhile to invest in advertisement as a function of the potential popularity of a content as well as its competing contents. The competition between similar contents (e.g. news channels) over a finite set of potential destinations. We then consider a second model in which there is also competition on advertisement space. We compute the equilibrium strategy and identify its structure and properties for each one of the situations.

Internet growth has allowed unprecedented widespread access to cultural creation including music and lms, to knowledge, and to a wide range of consumer information. At the same time, it has become a huge source of business opportunities. Along with great bene ts that this access to the Internet provides, the open and free access to the Internet has encountered large opposition based on political, economical and ethical reasons. An ongoing battle over the control on Internet access has been escalating on all these fronts. In this paper we describe rst some of the ideological roots of free access to the Internet along with its main opponents. We then focus on the problem of Internet piracy and analyze the e ciency of e orts to reduce the availability of copyrighted creations that are available for non-authorized free download.

“…When µ is less than 1 or greater than 11, the difference in the percentage of peers without the file is small. However, the case r = 1 has a much better file availability than the case r = 0.5 for µ in the range [1,11]. Figure 15 also shows that the proposed model matches the simulation well when λ is 0.03 and µ increases from 0 to 15.…”

We analyze in this paper the transient behavior of a simplified model for torrents in P2P networks. We consider a large number of peers interested in a file which is initially available at a small fraction of the population. Our model has as parameters the number of interested peers, the rate of arrival of download request, the rate at which peers propose files for upload, the degree of the free riding phenomenon etc. Our goal is to predict the impact of measures against P2P networks on their performance. We provide a Markov model that describes the detailed dynamics of the system. We analyze the model first under the assumption of an infinite population-an approach based on a branching process. This process is shown to provide a bound for the behavior of the system with finite population. We obtain the extinction probabilities for this process as well as approximations to the expected time till extinction. We then study the case of a finite population for which we establish the mean field limit. We show that the limit simplifies to a well studied epidemic model in case of no free riders. The fluid limit allows us to evaluate the behavior of the expected duration of a torrent, the expected number of nodes that eventually receive the file and the maximal availability along with the time at which it is achieved. We finally use these results to evaluate the efficiency of measures against unauthorized file sharing and their impact on file bundling.
