The article talks about how the Internet has changed how businesses operate, with many companies adopting new e-business models. E-business is more than just having a website or selling things online, it's about integrating customer needs, technology, and processes. There are digital products that can be sold online, like software, and physical products that need to be shipped, like books. Different types of companies are using e-business, like traditional "bricks and mortar" companies, online "dot coms", and hybrid companies like Amazon. Studies have shown that the value of information technology in businesses is often seen in terms of competitive advantage rather than just productivity gains.
