Anheuser-Busch InBev is down to three finalists in its domestic media agency search. OMD, MediaCom and Spark remain contenders, sources said.
Incumbent Starcom, which has handled research and media planning since 2011, was defending. The brewer began contacting agencies about its North American business in the spring and launched a review in July.
Top AB InBev brands include Budweiser, Bud Light, Stella Artois and Beck's. Busch Media, the company's in-house group, continues to run the brands' media buying.
Domestic media spending on all brands came to about $575 million last year, according to Kantar Media, and was more than $177 million in the first quarter of 2014.
Representatives for AB InBev did not return calls.
