In this chapter we revisit some portal research we conducted in Bangladesh and in Australia, the data collection of which was conducted in the early 2000s. We then investigate the evolution of these different types of web portal and how they compare ten years later. The concept of a web portal has been around for some time, but in the last few years the portal concept has gained considerably in importance as new types of portal are developed and new uses found for portal technology. This chapter begins with a brief classification of the types of portals in use today. Developed and developing countries experience different problems in making use of e-commerce and see the advantages and problems of using portals rather differently. In the chapter we examine and compare case studies of a Horizontal Business-Business Industry Portal in Melbourne, Australia, and a Vertical Industry Portal in Dhaka, Bangladesh.
