We investigate large-scale effects induced by external fields,phenomenologically interpreted as mass media, in multiagent models evolvingwith the microscopic dynamics of the binary naming game. In particular, we showthat a single external field, broadcasting information at regular timeintervals, can reverse the majority opinion of the population, provided thefrequency and the effectiveness of the sent messages lie above well-definedthresholds. We study the phase structure of the model in the mean fieldapproximation and in numerical simulations with several network topologies. Wealso investigate the influence on the agent dynamics of two competing externalfields, periodically broadcasting different messages. In finite regions of theparameter space we observe periodic equilibrium states in which the averageopinion densities are reversed with respect to naive expectations. Suchequilibria occur in two cases: (i) when the frequencies of the competingmessages are different but close to each other; (ii) when the frequencies areequal and the relative time shift of the messages does not exceed half aperiod. We interpret the observed phenomena as a result of the interplaybetween the external fields and the internal dynamics of the agents andconclude that, depending on the model parameters, the naming game is consistentwith scenarios of first- or second-mover advantage (to borrow an expressionfrom the jargon of business strategy).
