Good morning, and welcome to the new Omnicom, following its completion of the $13B mega-deal to acquire Interpublic Group (IPG), instantly making it the world’s largest holding company.

Omnicom

There is still a lot of work to be done within both agencies, as they continue to explore further cost-saving measures, which will unfortunately, result in most staff being laid off.  This will also take place here in Canada at all levels within the agencies under Omnicom and Interpublic.

As we mentioned last week, with two giant holdcos and millions of dollars in agency fees, CMO's will also have to make some tough decisions.
