A professor at a Catholic university in Manhattan teaches a lecture on evangelicalism to undergraduates each semester. The lecture starts with a photo of Billy Graham, and the professor asks students to identify him. The reaction to this question is consistent, although the specifics of the students' responses are not detailed.

The topic is explored further in an article available from Christianity Today. Further information on the lecture and the students' reactions can be found in the full article, which discusses the concept of spiritual revival and its significance in the context of evangelicalism.
