BMW Slaps Audi Dealership With Giant BillboardMatt Hardigree4/23/10 7:45pmFiled to: Billboard WarsAd WatchAudiBmwAudi of Hong KongAudi v BMWBMW v AudiAudi BillboardBMW BillboardTop811EditPromoteShare to KinjaToggle Conversation toolsGo to permalinkThe wall above Audi of Hong Kong is so gigantic it visually consumes their dealership. BMW clearly understood that, buying the space to use for a gigantic middle finger-like billboard over their German competitor. The billboard wars just went global.This whole tête-à-tête started last April when Audi put up a small billboard in California that said "Your move, BMW" with a picture of the Audi A4. BMW fired back with a giant picture of an M3 with the word "Checkmate" above it. Audi re-responded and that was the end of it until now.
