This chapter assesses the key motivations for those looking to oppose or protest against event bids, the strategies employed by successful movements and how bid campaigns have engaged, successfully and unsuccessfully, with groups in an attempt to mitigate their impact. It focuses on the growing interconnectedness of oppositional groups and associations, the acceleration of protest campaigns mediated through social networks, the increasing digital mediation of protest and resistance and the narratives employed by such groups to challenge bid orthodoxies. Foley argued that as events are incorporated into boosterist strategies, designed to assuage the multiple and complex problems associated with de-industrialisation in advanced western liberal democracies in particular, there are consequences in terms of the amplification of democratic deficits or legitimation crises. Historically, expressions of opposition to bidding for an Olympic Games, a FIFA World Cup or even a peripatetic cultural event have varied in their organisation, mobilisation, visibility and, ultimately, success.
