There's been much chatter about this Vodafone case study, which looks at an ad campaign created by advertising agency JWT for telecom giant Vodafone Egypt prior to the revolution. The study implies that the revolution happened.. due to this ad. With a straight face. While the case study is the usual chest-thumping we see so often in advertising, and the campaign has won a MENA Cristal Award just the other day, the tagline "the power between your hands" was uncomfortably ironic for those who recall that Vodafone shut off the network services back when they were really needed.
