Computer Associates was founded by Charles B. Wang in 1976, and by 2001 grew into the world's fourth largest independent software company. In 2001 it had 18,000 employees and was the dominant supplier of mainframe utility software. Over several decades it acquired a large number of companies in the areas of system management, manufacturing and warehouse, application development, financial reporting and applications, word processing, spreadsheet and project management, business applications, security, network management, and graphics and project management, among others; and by the end of the 1980s it was the first software company to exceed one billion dollars in sales.
