  Two long-lived senders play a dynamic game of competitive persuasion. Each
period, each provides information to a single short-lived receiver. When the
senders also set prices, we unearth a folk theorem: if they are sufficiently
patient, virtually any vector of feasible and individually rational payoffs can
be sustained in a subgame perfect equilibrium. Without price-setting, there is
a unique subgame perfect equilibrium. In it, patient senders provide less
information--maximally patient ones none.
