This is a short case study intended to introduce students to the world of electronic commerce as currently conducted on the World Wide Web (WWW) and the Internet. It does not focus on any particular firm, though it will be referenced by other cases. The case provides students who have access to Mosaic, or other Web browsers, with guided assistance in learning about the WWW's applicability to electronic commerce. Those without access to a browser will still gain a solid understanding of the possibilities. The case has three main sections. In the first, we look at an exciting new technological opportunity - the World Wide Web. Here we introduce the Internet, the Internet communications protocols (TCP/IP), the World Wide Web, and Web browsers such as Mosaic. In the second, we see how both small and large organizations are learning to harness this new opportunity to electronic commerce. The final section is intended to provide students with a high level understanding of how Web applications are constructed.
