We develop a model with two rival content providers where each is vertically integrated with a network operator. We are interested in determining a vertically integrated firm''s incentives: i) not to distribute its content over the rival network (network discrimination) and/or ii) not to allow the rival content access to its network (content discrimination). The equilibrium market structure and the number of contents that are available on the two networks is a monotonic function of the strength of consumer preferences for content variety. The equilibrium outcome is inefficient, but banning discrimination does not increase market efficiency. Discrimination, when it is practiced by one firm, harms its rival but not the competition.
