Augmented reality (AR) has been picking up steam for a little over a year now, so it was really only a matter of time before digital folks figured out a way to capitalize on it. Enter Brightkite, an Android and iPhone app that teamed up with Best Buy to run GEO-targeted ads on your cell phone, served up by Google. Arguably, though, Foursquare has been dabbling in a similar, but smaller, approach for several months.
The jury may still be out on whether this is incredibly effective advertising or an invasive annoyance. Either way, it’s an amazing application of mobile and AR.
