CompuServe

CompuServe was an American technology and communications company and one of the first major commercial online services. Established in Columbus, Ohio, in 1969 as Compu-Serv Network, it initially operated as a business-oriented time-sharing and remote-access service. Its computers were rented to corporations that needed processing capacity, while the company also developed an independent network business based on leasing otherwise unused mainframe capacity. The company’s consumer significance began in the late 1970s. In 1979, it worked with Radio Shack to sell evening access to its computers under the MicroNET name. The arrangement made productive use of capacity that was idle outside business hours and introduced personal-computer owners to interactive online services. The consumer operation was subsequently marketed as the CompuServe Information Service, or CIS. H&R Block acquired CompuServe in 1980 and supported an aggressive expansion of the service, helping it become one of the largest consumer information providers in the United States. During the 1980s and early 1990s, CompuServe offered a broad collection of services that anticipated many features later associated with the public internet. Members could exchange electronic mail, participate in moderated forums, use real-time chat, download software, access news and financial information, make travel arrangements, and play online games. The service also operated extensive libraries and supported communities managed by independent system operators. Its CB Simulator, introduced in 1980, became an influential commercial multi-user chat service. CompuServe was also an important venue for early online publishing and file exchange, including the distribution of images and software. CompuServe made notable technical contributions. It developed networking and file-transfer systems for its proprietary service and offered an X.25 interface to corporate customers. Its engineers created the Graphics Interchange Format, or GIF, in 1987 as a practical color-image format for online distribution. GIF later became widely used across the World Wide Web. The company also introduced or hosted influential services such as EaasySABRE, which gave consumers direct access to airline and hotel booking functions, and online games including MegaWars III and Island of Kesmai. The company expanded beyond the United States through arrangements with Fujitsu and Nissho Iwai in Japan, where a Japanese-language service known as NIFTY-Serve was developed, and through a Hong Kong joint venture with Hutchison Telecom. It also sold network connectivity and transaction-processing services to businesses. Its commercial network supported corporate hosts, financial-information applications, and large volumes of dial-up payment-authorisation traffic. CompuServe’s position weakened in the 1990s as America Online, Prodigy, commercial internet service providers, and the open World Wide Web offered simpler access, richer graphics, and more economical pricing. A complex transaction arranged with WorldCom led to AOL acquiring CompuServe in 1997. AOL retained the name as a sub-brand for a time, but stopped introducing new CompuServe-branded products in 2002. The original service, later known as CompuServe Classic, was finally discontinued in 2009. Although the brand is defunct as a general online service, CompuServe remains historically important for helping define consumer online communities and for popularizing technologies and practices that became standard on the internet.

CompuServe began in 1969 in Columbus, Ohio, as Compu-Serv Network, a subsidiary of Golden United Life Insurance. Its original purpose was to provide internal computing capacity for its parent while building a commercial time-sharing business. Customers connected remotely to company-operated computers and rented processing time, initially using the service primarily for business applications. The company gradually shifted toward packaged applications and network services rather than simply selling raw computer time. It became an independent public company in 1975 and changed its corporate name to CompuServe Incorporated in 1977. A proprietary packet-switching network, built with minicomputer-based network nodes, allowed the company to connect customers to host systems and later to offer connectivity to corporate networks. The network evolved to use several technologies, including X.25 interfaces, Frame Relay, ATM, and IP. Consumer access developed from an effort to use mainframe capacity during evenings. In 1979, Radio Shack marketed the service as MicroNET. The experiment attracted personal-computer users, and in 1980 the operation was renamed and promoted as the CompuServe Information Service. H&R Block acquired the company in 1980 and invested in its expansion. By the mid-1980s, CompuServe was a leading consumer information service, sold through computer retailers and supported by forums, software libraries, email, news, financial data, chat, games, and technical assistance. A distinctive feature of the service was its community structure. Independent system operators ran topic-specific forums and libraries, while users could communicate through message boards and live chat. Sandy Trevor’s CB Simulator, launched in 1980, became one of the service’s best-known applications. CompuServe also supported early online publishing, including newspaper text services, and hosted early online entertainment such as the 1985 comic Witches and Stitches. Its file-exchange systems helped users distribute software and images at a time when consumer internet access was not yet broadly available. The company’s technical legacy includes GIF, introduced in 1987 by engineer Steve Wilhite. The format was designed to make color images practical to exchange among different types of microcomputers and subsequently became a major web-image standard. CompuServe also developed its own file-transfer protocols, including the B and B+ protocols, and created services that connected consumers to specialist databases. EaasySABRE, introduced in 1985, enabled users to search and book flights and hotels through an interface linked to the Sabre reservation system. CompuServe expanded internationally in the second half of the 1980s and early 1990s. Fujitsu and Nissho Iwai helped establish a Japanese-language service, NIFTY-Serve, while a Hong Kong venture with Hutchison Telecom also gained subscribers. The company developed WorldsAway, an interactive virtual environment, with Fujitsu. Alongside its consumer business, CompuServe Network Services sold corporate connectivity and supported financial-information applications and payment-authorisation traffic. By the early 1990s, CompuServe was one of the three best-known consumer online services in the United States, alongside Prodigy and America Online. Its growth was constrained by relatively high connect-time costs, text-oriented interfaces, and increasingly intense competition. AOL’s more accessible pricing and graphical software, followed by internet service providers and the World Wide Web, changed consumer expectations. CompuServe lost market share and was acquired by AOL in 1997 through a transaction involving WorldCom. AOL eventually ended new CompuServe-branded product development in 2002. The legacy service continued under the CompuServe Classic identity until its closure in 2009.
