Ever heard of Blue Marble? If not, it’s a marketing service offered by an Austin, Texas based firm, Phillips & Company, that puts QR codes on rooftops.

Blue Marble^™ is a patent-pending marketing service offered by Phillips & Company that enables any business to transform its rooftop into a space-accessible billboard by integrating a dynamic QR code into the physical site, taking an aerial or satellite image from space and making it accessible in leading navigation applications like Google Earth^® and Google Maps^®.

It’s an interesting idea, although I’m not sure if I see it being the most effective form of advertising. In theory, yes, it could reach a large audience, but realistically the people who end up scanning the code are probably those stumbling upon it on accident. It takes about a year for the QR code to show up on Google, so it’s possible that could change in the future.
