Media Post: Pop-up vs. Pop-under: Researchers See No Difference
A good discussion of the pop scene, highlighting research that suggests that pop-ups and pop-unders are considering with equal disdain by users. Some disagree with this prognosis, most notably iVillage that made a big thing about dropping pop-up, but then continued to serve pop-unders.
Personally I think that it is fair to lump them together given that they both hijack the user experience by opening a browser. To suggest, as Peter Naylor, VP, general manager of sales at iVillage does, that the ìdifference is up vs. down, white vs. blackî is simply laughable, something that I'm certain that his audience will point out to him in due course.
