The college left its partnership with the Pestalozzi-Froebel Teachers College, named Norman Alexandroff as its president, and filed the Columbia College of Expression as a not for profit corporation on December 3, 1943. On February 5, 1944, the college re-filed as a not for profit corporation and changed its name to Columbia College. During the late 1940s and early 1950s, the college broadened its educational base to include television, journalism, marketing, and other mass-communication areas. Alexandroff also oversaw the development of the extension campuses of the school, Columbia College Pan-Americano in Mexico City, Mexico, and Columbia Los Angeles in Los Angeles, California. Both of these campuses became independent of its parent in the late 1950s. Prosperity was short lived, however, and by 1961, the college had fewer than 200 students and a part-time faculty of 25.
