William Franklin "Billy" Graham, Jr. (born November 7, 1918) is an American evangelical Christian evangelist, ordained as a Southern Baptist minister, who rose to celebrity status in 1949 reaching a core constituency of middle-class, moderately conservative Protestants. He held large indoor and outdoor rallies; sermons were broadcast on radio and television, some still being re-broadcast today. In his six decades of television, Graham is principally known for hosting the annual Billy Graham Crusades, which he began in 1947, until he concluded in 2005, at the time of his retirement. He also hosted the popular radio show Hour of Decision from 1950 to 1954. He repudiated segregation and, in addition to his religious aims, helped shape the worldview of fundamentalists and evangelicals, leading them to appreciate the relationship between the Bible and contemporary secular viewpoints.
