The emergence of Facebook represents one part of a more general shift in power away from
corporations and toward consumers (as highlighted, for example, by Lafley, 2006), one person’s
views or described experience can now reach millions of people in a very short period of time and, in turn, strangers are able to rally into communities and online groups with shared agendas. These consumer communities can help brands by harnessing emotional engagement and brand support or endorsement; for example, in the United Kingdom in 2007, Cadbury decided to reintroduce the confectionary brand Wispa, after a popular campaign on Facebook. Of course, the converse is also true; an online “mob” culture can be created quickly and easily to challenge a particular brand’s identity, service, or practices.
