According to a study conducted by the Software Publishers Association, 70% of the people in the United States getting access to the Internet do so through an online service such as America Online, CompuServe, or the Microsoft Network. The remaining 30% get their access from Internet Service Providers (ISPs).

People who do use an ISP tend to remain connected two hours more per week than online service users. Only 21% say they've made purchases online
