Consumer electronics retailer RadioShack is disbanding its in-house Circle R Group advertising unit and assigning its $250 million ad account to Havas' Arnold Worldwide unit, reports
The Wall
Street Journal. It's unclear whether RadioShack's media buying account was impacted by the move. Carat handles RadioShack's media account. Former Carat President Charlie Rutman joined Havas' MPG
unit as CEO this month.
