Michael Moore, of the University of Utah, and Richard Nash recognised the potential of an Internet chess server and created its first incarnation, hosted at lark.utah.edu and accessible through telnet. The official opening date of the ICS was January 15, 1992. John Chanak, William Kish, and Aaron Putnam moved the server to a host machine at Carnegie Mellon University in July 1992, and took over its operation. Although it was buggy and suffered from lag problems, the server was popular among a small group of chess enthusiasts. Over time, many features were added to the ICS, such as Elo ratings and support for graphical clients, and the server was made more stable.
