Another indexing system, WAIS (Wide Area Information Server), is developed by Brewster Kahle.
The WAIS protocol and servers were primarily promoted by Thinking Machines Corporation (TMC) of Cambridge, Massachusetts. TMC produced WAIS servers which ran on their massively parallel CM-2 (Connection Machine) and SPARC-based CM-5 MP supercomputers. WAIS clients were developed for various operating systems and windowing systems including Microsoft Windows, Macintosh, NeXT, X Window, GNU-Emacs, and character terminals. TMC, however, released a free open source version of WAIS to run on Unix in 1991.
