Extranet, Extranet: Changing Publishing Paradigms A Case Study of Extranets in Advertising

The Internet, Intranets and Extranets are completely changing the way corporations and governments are working and doing business. This paper defines Extranets, Intronets and Supranets and examines the electronic commerce domain matrix. The research concerns the relationship between inter-organizational systems in an existing cooperative supply chain and the Internet, using an Extranet. A Case Study of the AdOnline Project of the large publishing company, John Fairfax Holdings Ltd, illustrates how the Internet has been incorporated into the existing framework of the company and why it has been done this way. This Extranet enables favoured business associates to gain access to the core-business systems of the Fairfax publishing departments.
