At the height of the pop-up wars, it seemed like there was no end in sight: the future of the Web would be one where humans adapted to pop-ups, then pop-ups found new, obnoxious ways to command humans’ attention, which would wane, until pop-ups got even more obnoxious.
But that’s not how it happened. Instead, browser vendors (beginning with Opera) started to ship on-by-default pop-up blockers. What’s more, users—who hated pop-up ads—started to choose browsers that blocked pop-ups, marginalizing holdouts like Microsoft’s Internet Explorer, until they, too, added pop-up blockers.
Chances are, those blockers are in your browser today. But here’s a funny thing: if you turn them off, you won’t see a million pop-up ads that have been lurking unseen for all these years.
Because once pop-up ads became invisible by default to an ever-larger swathe of Internet users, advertisers stopped demanding that publishers serve pop-up ads. The point of pop-ups was to get people’s attention, but something that is never seen in the first place can’t possibly do that.
