Not content with owning Hollywood management companies and entertainment flackeries, the advertising conglomerate Interpublic has quietly moved from a minority to a majority stakeholder in Endeavor talent agency’s NY-based Endeavor Marketing. I’m told that IPG has held a 40% interest since 2005 but has now moved up to a 50%-plus holding in the company that reps such brands as American Express and Revlon. Run by CEO Mark Dowley, Endeavor Marketing keeps raising cash for the tenpercentery as well as gives the agency a foot in the door to the lucrative corporate branding market which all the Hollywood agencies are chasing these days. CAA and Willaim Morris in particular have very active corporate consultancies. And United Talent last year opened UEG (United Entertainment Group), a NY-based branded entertainment firm that’s a joint venture between UTA and Jarrod Moses. So it was surprising that the recent New York Times profile on Endeavor didn’t even mention that agency’s aggressive move in the marketing area begun back in 2000. Dowley came from McCann and IPG before joining Endeavor in 2003. I hear he’ll stay on.
