The work will focus on building the Fage-owned brand and promoting it as a healthy lifestyle product to consumers.
Unity will work closely with Fage UK’s PR and social media manager Alison White to extend existing comms, including a recipe-based website, which was relaunched at the start of the year.
Unity will also work with Total's brand ambassadors in food, nutrition and fitness.
Unity co-founder Nik Done, who will be heading the account, said: ‘I’ve been eating Total for years, so I am particularly happy to be working on this account. We hope this campaign will help generate real brand love in 2013.’
The Greek yoghurt market in the UK is valued at £73m, with Total currently the leader with a 33% value share of the market.
