Second AI Winter
From approximately 1987 to 1993, AI research entered a second sustained contraction as commercial expert-system vendors collapsed, the Lisp machine market failed, and DARPA substantially reduced funding for AI programmes following unmet expectations from the preceding boom.
Commercial Lisp Machine Market: Symbolics and LMI
From 1980 onwards, Symbolics Inc. and Lisp Machines Inc. (LMI), both founded as spin-offs from the MIT Artificial Intelligence Laboratory, commercialised dedicated hardware workstations designed to run Lisp natively, offering large address spaces, garbage collection in hardware, and early graphical interfaces tailored to AI development.
