The agency will start work in January on an integrated PR programme to celebrate the brand's heritage and ‘Every Day’ role in people’s lives.
Launch PR will initially work on a three-month project for the brand, reporting to Yakult UK PR manager Sonya Hayden. There is currently no retained agency in place.
Hayden said: "Launch’s creative thinking and results-driven mindset impressed us from the start and we’re delighted to be working with it in our anniversary year."
Launch PR founder and creative lead Johnny Pitt said: "Launch will mark its 15th birthday next year and has a proud history of working on anniversary campaigning for leading brands. Yakult has been in British people’s lives for 20 years now and that story needs celebrating."
