NEW YORK (AdAge.com) -- Mark Hass, CEO of the global PR firm MS&L, has left the agency to pursue other opportunities.
Until a replacement has been named, John Farrell, the president of Publicis Groupe's Specialized Agencies and Marketing Services, will work with the agency's leadership team to manage the firm, the company said in a brief statement.
Mr. Hass has been with the Publicis Groupe-owned agency since it purchased his firm, Hass Associates, in 2002. He ascended to the worldwide CEO position in 2005, succeeding Lou Capozzi.
No reasons were given for Mr. Hass' departure.
Under Mr. Hass' leadership, MS&L has been aggressive in rolling out new-media programs for clients through programs like its Blogworks practice and blog, which has posts going back to April 2005. That year it helped establish the FastLane blog for General Motors, which featured posts from Vice Chairman Bop Lutz and was noted for bringing a level of transparency to the automaker.
In a letter to industry contacts obtained by Ad Age, Mr. Hass said he is looking at opportunities with agency and corporations and completing a writing project on how companies and their leaders can "create value in an internet age by aligning themselves with a higher purpose." He also indicated he might start an independent PR firm.
M&SL suffered a blow recently when Philips Electronics moved its PR business to Omnicom Group, after a review. Recent wins include Evian and Puma.
