Visitors to PLASA 2005 who arrived by taxi may well have experienced the Cabvision system. Once inside the show they might also have seen another innovation by Devon Adsites' MD Jon Marquis - Adscreens. These are portable audio and video systems, worn like a rucksack, which can be used to promote a brand anywhere that a person can walk. "It's like a space-age sandwich board," smiled Marquis. Slightly less hi-tech is the AdJacket, following the same principle but featuring an illuminated panel which can carry a fixed advertisement poster.
