The first advertisements on the Web were whatever size the designer chose–the designer probably did the ad as well as the page. As internet advertising matured, predefined sizes became helpful, so that page designers would know how big a hole to leave for an ad, and ad agencies could prepare advertisements that would fit into many different Web pages, as they do in newspapers. The Ad Unit Task Force of the Internet Advertising Bureau (www.iab.net) has identified standard “Interactive Marketing Units.”
