WPP’s GroupM has continued its shopping spree with the acquisition of South African mobile marketing agency Yonder Media.

GroupM has confirmed it has acquired a majority stake in Yonder, as part of its wider strategy to develop its capabilities in digital media. The terms of the deal have not been released.

Founded in 2005, Johannesburg-based Yonder employs around 30 people and reported revenues of ZAR 20m ($1.4m) for the year-ended 28 February 2015.

The agency works with brand including Toyota, Fanta and First National Bank, and specialises in mobile and social media strategy, media planning and buying and app development.

WPP now claims to generate revenues of around $500m in South Africa, employing approximately 26,000 people.

It comes a week after GroupM announced the acquisition of global digital agency Essence.

Managing a media spend of over $700m, London-based Essence employs 500 people in the UK, New York, San Francisco, Seattle, Singapore and Tokyo. It will continue to operate independently under WPP and GroupM.

Last month, WPP revealed it has completed 38 acquisitions in the first nine months of the year, the majority of which involve companies with digital and data expertise.
