Using a specially designed Facebook app and social-network analysis, the current authors revealed that approximately half of campaign-related conversations are initiated intentionally by campaign participants—individuals who deliberately create opportunities to talk to conversation partners in ways aligned with the campaign sponsor's commercial objectives. The other half emerge in everyday conversation. Participants also deliver the brand message into about half of the social-network clusters to which they belong. For a higher proportion of network clusters to be activated, everyday conversation should be facilitated.
