Popup

"The overall definition of a pop-up is a browser window that appears out of nowhere as you are viewing content on the web."

"There are three primary types of pop-ups: those that appear when clicking something on a web page, those that appear at random, and those that appear without user intervention, the most aggravating variation. More often than not, these busy windows exclusively display ads for content the user has no interest in." One of the best ways to get rid of popups is to upgrade your browser. Please at least up to Google Chrome, it helps keep you very organized."Instead, there is a graphic within it that appears to be another pop-up window."

[] James Loftus

=pop-up ad = A type of window that appears on top of (over) the browser window of a web site that a user has visited. In contrast to a pop-under ad, which appears behind (in back of) the browser window, a pop-up is more obtrusive as it covers other windows, particularly the window that the user is trying to read. Pop-ups ads are used extensively in advertising on the Web, though advertising is not the only application for pop-up windows. [] -Lisa
