Radio: Big Show

Beginning next week, the U.N. General Assembly goes on television with a commercial sponsor: the Ford Motor Co. While the session lasts (probably more than a month), Ford will pick up the tab for 15 hours a week (CBS-TV, 11 a.m.1 p.m., 3-4 p.m. Mon. through Fri.) over a network of 21 stations—the largest time sale in TV history.
