I review some developments in the large-N gauge theory since 1974. The main
attention is payed to: multicolor QCD, matrix models, loop equations, reduced
models, 2D quantum gravity, free random variables, noncommutative theories,
AdS/CFT correspondence.Comment: 13.1pp., Latex, 2 figs; v2: 2 refs added. Talk at Large Nc QCD 200
