This document summarizes a study on the impact of social networking sites on e-businesses. It finds that e-businesses increasingly use social media like Facebook, Twitter, and Myspace to increase brand awareness, get customer feedback, and expand their business markets. The literature review cites sources finding benefits for e-businesses like promoting products through word-of-mouth and allowing customers to engage in conversations. However, social media also creates issues around privacy and data retention that companies must be aware of. The study examines the most popular social sites used by UK e-businesses and the reasons for their use over time.
