One agency source added that “the portfolio is so big” that Wrigley may consider splitting the account between two agencies.
Agencies believed to be participating in the review include Agenda, Agency.com, Digitas and Tribal DDB.
Sources say Wrigley may announce its result as early as the end of the month.
The review comes during an active summer for the brand in China. In July, Wrigley launched a cost benchmarking exercise in the market connected with its media account. MEC, the incumbent agency on the account, Starcom and Zenith Media were confirmed to be involved in the process, designed to assess the client's media buying needs. Sources suggest OMD was also involved.
