Looking for a ‘patented amphibious billboard?’ Advertisers like McDonald’s, Disney and Mitsubishi apparently are. They’ve all used floating billboards by Malibu-based media supplier Billboard Boats.

The billboards can float on water or glide across sand, snow, grass, dirt or pavement. They’re airtight and light enough to be towed by a boat, Jet Ski, golf cart or bike. Advertisers can customize the size of their floating billboards, and even link several together. www.bbidisplays.com
