Over the past few years the web has grown to several hundred million pages, while just a few of them get most of the visits. Such sites, called portals, attract visitors, advertisers and provide lots of valuable content at no charge to the visitors. The portals attract a disproportionate amount of the Internet advertising dollars and have the ability to influence the success of new electronic commerce ventures. In this paper we show the evolution of portals from a web in which all pages are equally accessible. In addition, we show the impact of technological developments and added services.
