ABSTRACT
Imagine that your friend Aimee is sitting at her computer, navigating through the Web and exploring a variety of sites. She goes to a search engine to locate possibilities for tonight’s entertainment in Boston, and as she does so, an icon on her desktop updates the current temperature and weather conditions in her area. When she continues her search for evening activities, the search engine provides her with several sites that seem related to what she’s looking for, from newspaper Web sites to entertainment guides to travel brochures. As she scans these sites and learns what she wants to know, a few pop-up ads appear o¡ering her subscription to entertainment magazines and discounts on tours of Boston. A¤er a few minutes, Aimee has –nished scoping out Boston’s evening scene, so she logs o¡ the network and calls her friends to plan for the night’s activities.
