BINAC, the world's first commercial, electronic, stored program, digital computer passed verification tests here, at 3747 Ridge Ave., on April 7, 1949. Customer acceptance of UNIVAC I, the world's first open market, commercial computer, followed on March 30, 1951. J. Presper Eckert and John W. Mauchly, co-inventors of ENIAC, led the development of both of these pioneering machines, which launched the commercial computer age.
