Ad account shakeup.

Some big-money advertising accounts have moved around the L.A. metroplex during this year's third quarter. All the switches involve billings worth at least $100 million, and all the clients work in the media sector.

Lions Gate Entertainment, based in Vancouver but with a large L.A. footprint, earlier this month moved its $130 million account to Initiative, a New York-based unit of Interpublic Group. The business previously belonged to Palisades Media Group in Santa Monica. During the same week MGM moved its $100 million account from Palisades to Rubin Postaer & Associates, also in Santa Monica.

Finally, Expedia Inc. parted company with Interpublic's Deutsch/LA in Marina del Rey. The travel site gave the $170 million account to Doner, an independent agency in Southfield, Mich. Doner beat another local agency--Omnicom Group's TBWA\Chiat\Day in Playa del Rey--for the business.

However, the biggest L.A. media cookie remains on the table. News Corp.'s Fox film divisions have put their $1 billion consolidated account into play. Interpublic has dropped out of competition because it won the business from competitor Lions Gate. Until now, New York-based Mindshare has handled most of the Fox media buys.
