DescriptionTime-sharing is a technique which provides many users simultaneous access to a central computer through remote terminals so that each of them appears to have access to the machine on a full-time basis. The companies included in this project are representative of those companies which were founded during the period of 1964 through 1980 that offered time-sharing services. They used mainframe computers to provide these services and usually offered their customers access to software applications as well as billable cycles of machine time. The time-sharing companies offered customers remote access to powerful computers over communications networks so they could run their applications themselves using their own software or that provided by the time-sharing service provider. This differentiates them from remote processing services companies such as EDS or ADP where the service provider ran the job for the customer.
