Title

Portals: pointers to the future? : Traditional information providers grapple with this new online strategy

Abstract

Presents a view of portal sites as a radically different model from those currently embraced by traditional information companies. The concept of a portal as a starting point that Web users pass through is an uncomfortable one for most traditional services, which are designed to be one-stop destinations for information. It will become increasingly difficult for even the largest data warehouses to compete with the rising volume of Web content if closed end information models are not abandoned in favour of distributed ones which better reflect the reality of what is available to information consumers. Dow Jones Interactive Publishing is among the first to embrace a distributed model by indexing the sites which it believes have customer value, regardless of whether they offer their content on the subscriber service
