E-business refers to conducting business electronically and integrating technology like the internet to streamline processes. In the late 1990s, many companies rushed to adopt e-business due to hype, but costs were high and customers were still uncomfortable using the internet. This led to the dot-com crash. Now, internet penetration is higher, costs are lower, and companies have refined their e-business models. E-business allows for speed, convenience, customization and new ways of defining product value compared to traditional business. The key benefits are cost reduction, increased sales, improved customer service and expanded markets.
