Oral Roberts began his career as a tent evangelist in the late 1940's, appearing at rallies and evangelical crusades throughout the United States and the world. He was at his peak of popularity as an evangelist in the 1950's and 1960's. His meetings were popularized by his fiery and rapid-fire style of delivery, and the ever present lines of people hoping to obtain their healings.
In the late 1970's, Oral Roberts' career began to take a different course as he founded the university that bears his name and began to move away from the crusades and concentrate on the medium of television. His folksy, homespun style and fatherly character made him a popular personality, and his television programs expanded throughout the country.
Oral Roberts' television program, books and university have all become a central distribution point for the health and wealth gospel and his promotion of the "seed faith" doctrine has brought in untold millions to his organization.
