The penultimate final frontier, adverts directly in front of your eyeballs 24/7, and tracking not just your position but your attention.

Only step beyond this is neural implants putting purchasing decisions directly into your grey matter.

Maybe the next step of the business plan is to sell blue (or green) screen shirts to individuals on which AR glasses can display targeted advertising that only you see (eg: everyone you see in those shirts is wearing Nike gear, but everyone I see is wearing Ralph Lauren because I am fancy).

Then everyone whose shirt is used to display ads can get revenue-share.
