Westlaw - History

History

Both Westlaw and LexisNexis started in the 1970s as dial-up services with dedicated terminals. The earliest versions used acoustic couplers or key phones; then smaller terminals with internal modems. Westlaw's terminal was known as WALT, for West Automatic Law Terminal.

Around 1989, both started offering programs for personal computers that emulated the terminals, and when Internet access became available, an Internet address (such as westlaw.westlaw.com) became an alternative that could be selected within the "Communications Setup" option in the client program, instead of a dial-up number. West's program was known as Westmate. It was based on Borland C++ around 1997, and then changed to a program compiled on a Microsoft platform that incorporated portions of Internet Explorer. This was the first program to incorporate HTML; prior to that, Westmate had "jumps" indicated by triangles instead of "links." Shortly after that, both publishers started developing web browser interfaces, with Westlaw's being notable for the use of "web dialogs," emulating the piling of open books on a table. Westmate was discontinued on June 30, 2007.
