Adblock the real world

As augmented reality moves from handheld devices like the iPhone to graphical-overlay glasses (soon!), it will be able to — for example — block out real-world display advertising. Sort of the way ads are currently digitally inserted into broadcast of sporting events. (A passing thought from an article on AR in The Atlantic, which yes, I am going to keep linking to every single month, because the Atlantic is the best magazine evar.)
