National CSS was founded by Bob Bernard and Ken Bridgewater in 1966 as Computer Software Systems, performing technical consulting services. In 1967 they were joined by Dick Orenstein and started to create a timesharing company using IBM's 360/67 with a system based upon the CP67 and CMS programs developed by IBM's Cambridge Science Center. NCSS focused on providing its customers with remote, online interactive program development capability including source language program debugging and later the use of 4GL products (NOMAD). NCSS went public in 1970, and after some serious downsizing during the recession of the early 1970s became a strong, profitable company during the mid and late 1970s. NCSS was sold to Dun & Bradstreet in 1979 and continued as a separate division within D&B.
