Pop-up ads are a type of online advertising on the World Wide Web intended to enhance web traffic or capture email addresses. It works when particular web web-sites open a new web browser window to display advertisements. The pop-up window containing an advertisement is usually generated by JavaScript, but can be generated by other indicates too.

A variation on the pop-up window will be the pop-under advertisement. This opens a new browser window, behind the active window. Pop-unders interrupt the user much less, but aren’t observed until the desired windows are closed, making it more tricky for the user to figure out which Internet internet site opened them.

For early advertising-supported web web-sites, banner ads had been sufficient revenue generators, but in the wake of the dot com crash, costs paid for banner advertising clickthroughs decreased and lots of vendors began to investigate much more effective advertising procedures. Pop-up ads by their nature are difficult to ignore or overlook, and are claimed to be far more successful than static banner ads. Pop-ups have a much higher click rate than internet banner ads do (about every 14,000th popup ad is clicked on).

Pornographic web sites are among one of the most frequent users of pop-up ads. Some especially vicious types of pop-up ads (once again, most frequently observed in connection with entertainment internet sites) appear to have either been programmed improperly or have been specifically designed to “hijack” an user’s World wide web session. These forms of pop-ups at times spawn several windows, and as every single window is closed by the user it activates code that spawns another window — occasionally indefinitely. This is at times referred to by users as a “Java trap”, “spam cascade” or “Pop-up Hell” amongst other names. Often the only strategy to stop this is to close the browser.

Opera was the first major browser to incorporate popup-blocking tools; the Mozilla browser later improved on this by blocking only popups generated as the page loads. Within the early 2000s, all significant internet browsers except Web Explorer (then the most popular browser and still as of 2006) allowed the user to block unwanted pop-ups almost completely.

In 2004, Microsoft released Windows XP SP2, which added pop-up blocking to World-wide-web Explorer. Lots of users, however, remain unaware of this capacity, or else pick out not to use it. Many others aren’t able to use it at all, as they do not use Windows XP SP2, but older versions of Windows. Some users install non-Microsoft ad-blocking software program instead.
