Pop-up ads or popups are a form of online advertising on the World Wide Web intended to attract web traffic or capture email addresses. It works when certain 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 means as well.

pop-under advertisement,opens a new browser window hidden under the active window. Pop-unders do not interrupt the user immediately and are not seen until the covering window is closed, making it more difficult to determine which web site opened them.
This is very helpful information. Now i know more about the pop-under. By the way, I dont like both of them.
