Dive Brief: 

• Publicis Groupe's MediaVest is AdWeek's U.S. Media Agency of the Year. 
• In 2013, the agency saw its revenue grow 30%. 
• The growth in business was led by the big win of the highly sought-after Honda account. 

Dive Insight: 

MediaVest certainly has a lot to be proud of this year. With high revenue growth and the scoring of major deals, the agency has cause for celebration. Not only did MediaVest score big name new clients, but a great deal of revenue growth came from growing its relationships with existing clients. That is the mark of true agency ability — to grow both with new clients and existing.
