Swedish clothing retailer Hennes & Mauritz has launched a U.S. media review, per sources.
The company spends close to $25 million annually on U.S. ads, according to Nielsen.
The incumbent is WPP Group's MediaCom, which has elected not to defend, sources said. A list of contenders was not immediately available.
MediaCom declined to comment, referring queries to the client. An H&M rep did not return a call.
The retailer entered the U.S. market in 2000 and now has over 200 stores. H&M reported worldwide sales of roughly $1.4 billion in 2010.
