Omnicom's OMD unit this morning named Ben Winkler its chief digital officer. Winkler who was senior vice president-director of digital at Interpublic's Initiative, was one of two top digital appointments announced. The other was Colin Sutton, who joins OMD as head of OMD Word, the media agency's social media unit, from managing director of GroupM's M80.

Before Initiative, Winkler was vice president-interactive media at the Martin Agency, and before that, media director of i33 Communications.

He reports to OMD US CEO Alan Cohen. Sutton will report both to Winkler and Cohen.
