A Brief History of A.I.
1950's: Computers process concepts as well as data; the first laboratories and conferences focusing on artificial intelligence are organized.
1960's: Advances include industrial robots; an expert system that maps the structure of complex chemicals; robot vision; and simple voice recognition.
1970's: Computers, learning from experience, evolve their own rules of behavior; language analyzers draw valid inferences from newspaper articles; and a computer becomes the world backgammon champion.
1980's: Fuzzy logic, a form of analysis based on assigning varying weight to data, is used by industry; expert systems expand rapidly; huge databases are used in a search for complex patterns in financial markets and the weather; and venture capital pours in as expectations outdistance performance.
1990's: Though the term is rarely used, artificial intelligence advances on every front -- including chess, with a computer for the first time beating the world champion.
