Information glut is a phrase that comes to mind.
Information explosion is the experience.
The Web explosion is occurring because a critical mass of enabling technologies and market conditions has met a pent-up demand for a new way of linking people and information. These market enablers touched off an explosion of demand for Web services, providing people with a new and better way of linking up with information. Previously, the Information Age had inundated people with data that was out of date, incomplete, or irrelevant. What we needed instead, and what the Web provides, is a way for people to easily access the information they need, when they need it. To access the Web, you need a browser, a modem, and an Internet service provider.
