Battersea Dogs and Cats Home have today launched a new form of digital outdoor advertising in which a dog on a billboard appears to follow shoppers as they walk past. Created by OgilvyOne UK as part of the charity’s "#LookingForYou" campaign, the billboards are activated by a tag contained in leaflets that are handed directly to passersby at the Westfield Stratford shopping centre in East London. The RFID tag starts a video of Barley, a former Battersea dog, who begins to interact with the viewer.
