Part of the Internet acronyms and lingo glossary: A pop-up ad is a pop-up window used for advertising. When the program is initiated by some user action, such as a mouse click or a mouseover, a window containing an offer for some product or service appears in the foreground of the visual interface.
If a banner ad just sat there in the corner of the screen, a pop-up would make you stop what you were doing. âWe could have put in controls for those, and we should have,â Eich said. By the fall of 1997, pop-up ads showed up on several of the biggest sites, including GeoCities, AOL and The New York Times. âThey proliferated for one simple reason: They were effective,â says Rich LeFurgy, founding chairman of the Interactive Advertising Bureau and now an industry consultant at Archer Advisers.
