Plinking.

I have always viewed the advertising-funded model for Web 2.0 businesses to be rather close to interruptive marketing for my liking (and yes I view adwords as quasi-interruptive as the tendency for people to ignore the right-hand column of websites would seem to suggest).

Perhaps, Plinking or product placement linking is the answer. If linkable visual or text content allows the viewer/reader control of the click-through without impinging on their online experience, then we are getting much closer to true permission marketing.
