The agency will handle digital and social work for all Cadbury brands, which include Dairy Milk, Marvellous Creations, Wispa and Creme Egg.
Elvis was appointed after a competitive pitch against We Are Social and AKQA. Cadbury’s owner, Mondelez International, initiated the process in order to consolidate Cadbury’s roster of digital agencies into a single shop.
Lucy Evans, the marketing manager at Cadbury, said: "We have a packed year ahead, and Elvis’ expertise and creative flair will help us deliver world-class digital and social campaigns."
Elvis previously ran a social media campaign to publicise that Creme Eggs are only sold for three months of the year and encouraged Facebook fans to "have a fling" with the snack. It was Cadbury’s most successful European social media activity to date.
Tanya Brookfield, the managing director at Elvis, said: "Our work for the Creme Egg brand has been recognised and awarded globally, and this win will see a continuation of best-in-class digital and social campaigns across all Cadbury brands."
Cadbury’s creative and media agencies, Fallon and PHD, are unaffected.
