Very similarly, many other companies benefit from introducing e-commerce into their business models, even smaller companies that market their products through third-party suites such as e-bay are booming. Thus, the internet can help a company to diversify in two ways: (a) Diversifying customer-base (ex: selling on ebay or on own website through e-commerce solutions) and (b) Diversifying product range (similar to what HP did). Moreover, the internet enables faster communication by the means of VoIP (Skype, IM, Yahoo!) and e-mail, and of course the easy promotion of a business by the means of social networking websites such as twitter or Facebook. Furthermore, websites such as YouTube and Vimeo are just more cheap promotional methods to increase customer base or help in the launch of a new product. Not only that but web 2.0 can also help a company earn more revenues, such as revenues from advertisements on owned website and revenues from selling products from related industries and acting as an agent.
