Big media buyer MediaCom North America Thursday named Sasha Savic to the new position of CEO, MediaCom USA.

Most recently chief operating officer of Havas Media Group North America, Savic will start in New York in early spring reporting to MediaCom North America chief executive Harvey Goldhersz, who also serves as vice chairman and chief operating officer of MediaCom Worldwide.

”Ever since I became CEO of MediaCom North America a year ago, I knew I wanted to name a CEO for our U.S. operations,” Goldhersz said. ”I’m very happy to announce today that we’ve found precisely the right person for this important new position. Sasha is a strategic thinker and innovator with exactly the kind of extensive media agency credentials that MediaCom needs to lead our U.S. operation as we plan for 2012 and beyond.”

Savic will be responsible for the overall product, management and operation of all MediaCom activities in four U.S. cities, overseeing an agency with an estimated 700 employees and $6.4 billion in billings. Savic has also been EVP, Global Managing Director, for SMG/Publicis Groupe. Prior to that he worked in Europe and the U.S. for Universal McCann.

A native of Bosnia, Savic began his career as a founding member and producer of Youth Radio, the first independent radio station, in the former Yugoslavia.
