Since then, OMD has grown into one of China's most successful, culminating in the win of the Johnson & Johnson business last summer.
Barry Cupples, Omnicom Media Group's Asia Pacific CEO, said: "Maggie is one of the pillars upon which we have built our global business. It is due to personalities like Maggie that OMD has enjoyed the success it has seen over the last ten years."
Choi, who will remain based in Hong Kong, said: “it’s an exciting time for media agencies. Evolving client needs, fast changing market dynamics and the continued proliferation and segmentation of media platforms are all huge opportunities as well as challenges. It’s a great pleasure to be working
with a great and passionate team.”
The shift in Choi's role will give Cupples more time to focus on acquisitions, diversifying its services and fine-tuning the positioning of the OMG media agencies OMD and PHD.
