Based in Hong Kong, O’Donnell (pictured) will focus on driving transformational partnerships with media owners and technology platform providers around the world.
Annie Rickard, global CEO of Posterscope in London, said O'Donnell's sound knowledge of the sector and the region would "drive Posterscope forward as we invest in our business to deliver global solutions for our clients".
The appointment marks the first global role outside London for Posterscope, which underscores the importance of Asia for the division's growth.
O’Donnell has over 25 years of OOH advertising experience, most recently at Kinetic Worldwide. He spent eight years with the company in Europe and Asia, and resigned from his post as regional CEO last September. Prior to that, he worked at Clear Channel in the UK and in the technology startup space.
