Uber is switching its $600 million ad buying business from WPP to rival Omnicom, according to two people familiar with the matter. Uber began a competitive pitch for its media business in March. Florian Adamski, Omnicom Media Group CEO, said in a statement that its agencies would make its "strategic data capabilities" central to its work for Uber. Omnicom media agencies have notched up a handful of sizeable wins since the beginning of July. New business has included the $585 million Beiersdorf account, the $150 million global HSBC business, and the $150 million brief from lottery operator Allwyn Entertainment, according to marketing industry tracker COMvergence.
