When you sell ads you need to give your customer some idea of who will see the results of their investment. That explains this rather odd partnership of two sister companies: Erudite Inc., who makes tracking and security devices for shipping containers, and GBoards Inc. who is selling advertising on those shipping containers. In a promotion related to the 2008 Olympics, the companies have created the China8 Project. In May a dragon-headed ship will sail to China carrying humanitarian aid and merchandise giveaways. The trip will test out Erudite’s tracking and be, literally, an advertising vehicle. According to the Puget Sound Business Journal, offshore cell phone provider SeaMobile has signed on as the first advertiser. A 40-container advertising package is $1.2 million and the plan is to place the ad-covered containers in various locations in Shanghai and Beijing for 180 days.
