Pernod Ricard believes it has hit on the right formula for the latest outdoor advertising for anise spirit Pernod. Its latest poster campaign, called Social Chemistry, will be unveiled this month on 2,500 sites around London, including billboards, bus stops and underground stations. Pernod was revamped two years ago and marketing director Mark Davis said: "The campaign reflects the new strategy for the brand, targeting 25 to 35-year-olds and suggesting how the ingredients and appearance of Pernod-based drinks stimulate the senses and bring to life the social occasion. Our aim is to challenge people's perceptions of the brand." {{DRINKS }}
