Unlike many interviewers, King had a direct, non-confrontational approach. His reputation for asking easy, open-ended questions made him attractive to important figures who wanted to state their position while avoiding being challenged on contentious topics. King said that when interviewing authors, he did not read their books in advance, so that he would not know more than his audience. Throughout his career, King interviewed many of the leading figures of his time. According to CNN, King conducted more than 30,000 interviews in his career.
