ambush marketer
n.— «Beginning on Friday, the Chinese government will begin restricting advertising space in Beijing, giving preference to the official sponsors of the Olympic Games. The restrictions are meant to clamp down on so-called ambush marketers, which are companies that are not official sponsors but hope to gain some halo effect from the Games. One advertiser that is likely to suffer the most is Nike, which has broad marketing ambitions in China but no qualifying sponsorship deal.» —“Olympic Sponsors to Benefit Under a Tougher Stance in China” by Stephanie Clifford New York Times July 11, 2008.
