A compact chronological index of major AI milestones. For narrative depth, see History.

1950s

  • 1950 — Alan Turing publishes Computing Machinery and Intelligence; introduces the Turing test.
  • 1956 — Dartmouth Workshop coins the term “artificial intelligence.”
  • 1956 — Logic Theorist (Newell & Simon) proves theorems via search.
  • 1958 — McCarthy creates Lisp; Rosenblatt develops the Perceptron.

1960s–1970s

  • 1966 — ELIZA (Weizenbaum) simulates conversation; Shakey robot begins autonomous planning.
  • 1969 — Perceptrons (Minsky & Papert) analyzes perceptron limits.
  • 1975 — MYCIN expert system for medical diagnosis.

1980s

  • 1986 — Rumelhart, Hinton & Williams publish backpropagation for multilayer networks.
  • 1987 — LISP machine market crash contributes to an AI winter.

1990s–2000s

  • 1997 — Deep Blue defeats Kasparov at chess.
