The new billboard - Advertising in store windows

Selling Ad Space Into Store Windows: The New Billboard Business

As marketers and media buyers scramble for more street-level advertising space in big cities, store windows are emerging as a new kind of billboard business. Store operators and building owners are going for the idea because it turns underused window space into cash. A growing number of marketers like it because new technology can make window advertisements three dimensional and interactive -- and more likely to directly engage pedestrians.

Again, thanks to AdAge for this insight into the newest way that advertising will start to invade our lives and our sanity... although I do think that the interactive 3D animations would be fun and could hopefully provide some higher purpose. Combine this space with the technology of billboards with eyes* that I posted an article about ("Billboards that look back" June 2) a few weeks ago, and it is also a highly targeted media.

*These 'eyes' are cameras that capture data about passers-by, e.g gender, approx. age, etc
