By the second half of the 1960s, NRI recognized that its limited resources would preclude it from maintaining its leadership position within the industry in the coming decade. James Morrison Smith thus set out to find a partner/buyer. In 1968, McGraw-Hill Education agreed to purchase NRI, after having bought the correspondence division (20%) of Capitol Radio Engineering Institute in 1964. By this time, over one million students had completed an NRI course. McGraw-Hill had anticipated this would open a new market for technical books, while NRI hoped a significant advantage to the acquisition would be their ability to utilize the vast technical publishing resources of its new owner. The McGraw-Hill name began appearing in the NRI Journal in 1970. It was 1973 when the McGraw-Hill name began appearing in catalogues of copyright entries for NRI courses in the U. S. Library of Congress, and 1974 when it started to appear in magazine advertisements. After completion of the deal, the school was renamed once again to NRI Schools, and became part of a newly established McGraw-Hill Continuing Education Center.
