This was a somewhat interesting book detailing and describing the changes and methods employed for Evangelism in America. A historical book that does a fairly good job of providing an overall picture from the town-to-town evangelists, Methodism, television and radio evangelists such as Oral Roberts, and the pinnacle of modern evangelism, Rev. Billy Graham. Explores some of the successes and problems associated with different methods and then points to some of the current methods employed such as Evangelism Explosion, Campus Crusade, etc.
This is not a "how to" book on evangelism, but rather a who, when, where and why book.
