The Internet represents an extraordinary opportunity to converse with people all over the world; online communities provide a framework in which to exchange ideas and information, build relationships, and interact. People who often frequent a specific community are referred to as "members," and loyal members consider these communities part of their "corner of the Net" (meaning they stop in every time they get online to check on things). In the industry, online communities are considered one of the three big C's: content, commerce, and community. Businesses, especially dot-coms, try to create online communities of users and subscribers to attract more customers, build loyalty with their audience, and grow a database of contacts for marketing. Ultimately, the business model is either to sell these lists or to get a variety of sponsors to advertise to the community's special needs.
