Internet Service Providers (ISP's), which first began to emerge in the late 1980s and early 1990s, are the businesses and organizations that provide users with Internet access and related services. These providers connect customers to customers of other service providers by way of networks. Often, Internet Service Providers (also called Internet Access Providers) are companies that provide telecommunications services including data communications access and telephone connection. The majority of telephone companies now function as Internet Access Providers as well. ISP's may be commercial, non-profit, privately owned or community-owned.
