Marketers aren't willing to waste any potential ad space these days. We've covered the advantages of mobile billboards before, but this bus, which I saw from the 15th floor of Toronto high-rise, not only had its sides and back plastered in ads, but the top of its roof as well.
It's an excellent ad medium considering high rises, both residential and commercial, are ubiquitous in big cities around the world. That and the fact that more people are using public transit due to higher gas prices and heightened environmental awareness, makes it safe to assume mobile roof-top ads will become a mainstream form of advertisement.
