We consider the game theoretic model of competitive information diffusion recently introduced in Alon et al. (2010) [1]. We show that for the case of 2 competing agents, there exists a Nash Equilibrium for this game on any tree. We also present an example to show that this is not necessarily true for 3 or more agents.
