Year it was supposed to blow: 1997–
What happened: Augmented reality was first defined in 1997 by Roland Azuma who said AR is when the real world is augmented with real information. You’ve seen in in professional settings, most prominently in sports—the first down line in football, for example. However when it comes to consumer applications, augmented reality just hasn’t panned out. We’ve seen many iterations of this AR in the past few years from nearly every electronics company ranging from Nintendo to AT&T. Some games have proven the technology useful, but we’re still waiting for that one app to change our mind.
