DoubleClick is nearing an acquisition of ad management firm Falk eSolutions, its strongest rival in Europe, where Mediacom, mediaedge:cia Netherlands and ZenithOptimedia are Falk clients, writes ClickZ, citing a source familiar with the deal, which has apparently been in the works for some two months. Falk's AdSolution platform offers ad delivery for publishers and advertisers.

DoubleClick was acquired last year by Hellman & Friedman and JMI Equity and later sold off its email division to Epsilon. Last year, in order to offer rich media compatibility, Falk purchased Commflash's parent company.
