CUC is generally considered the first company to develop software independently and to have pioneered the field of programming services.

Trimble headed a project to computerize the air traffic control system of the Federal Aviation Administration.

In April 1960 the company had an initial public offering of stock shares, and grew to three managers, 37 mathematicians, 6 physicists, and 3 engineers.

[6] Later in 1960 CUC established a division to sell computer time and in Spring 1961 opened an office in Los Angeles.

[9] In 1965 the Computer Usage Education subsidiary was formed, headed by Ascher Opler, which published software books and offered courses.

Kubie and Reynolds left in July 1968 and the company changed direction under new president Charles Benton, Jr. from IBM's Federal Systems Division.

Other potential mergers were discussed, including Ross Perot who by now had founded his own service business Electronic Data Systems.

[9] CUC negotiated a contract to manage computer facilities at the Firemans Fund Insurance Company, which restored profitability for a time.
