Dive Insight: 

• Originally projected for the end of 2013, the merger of Omnicom and Publicis still has no set closing date in sight.
• One hurdle holding up the finalization of the world's largest agency holding company is the delay of China's antitrust approval, but the deal has been approved by the U.S., the European Union, and 12 other countries already. 
• Because of the global nature of the deal, tax agreements are also a sluggish process. 

Dive Insight: 

The agency world has been anticipating this merger for quite some time. The deal will set a lot of precedents for the industry as a whole, not including the unprecedented size of the merger. The question to ask is, is this drawn out merger process reflective of how every approval will be within the Omnicom-Publicis juggernaut? If so, the merger could cause the companies to lose some speed — and, therefore, advantage — to other companies.
