Although WPP Group and its ad holding company rival Publicis Groupe have been concentrating more in Asia and other emerging markets for their digital acquisitions lately, it seems there are still a few independent targets to be found in the U.S. One of the remaining ones was Seattle’s PBJS, which was just picked up by Publicis. Terms weren’t disclosed. The five-year-old shop concentrates on on “multichannel events” and branded entertainment, including webcasting and video production. The main thing that drew Publicis to PBJS was access to the agency’s biggest client: Microsoft (NSDQ: MSFT). That could bring more closeness between Microsoft and Publicis, which is working with the software giant, as well as Yahoo (NSDQ: YHOO), Google (NSDQ: GOOG) and AOL (NYSE: TWX) on an open source ad network. The 26-person PBJS will continue to operate independently, though it will exist within Publicis Events Worldwide unit. Founder and CEO Bob Bejan will remain in that role, reporting to John Farrell, President & CEO of SAMS. Release (PDF)
