William Franklin Graham Jr. was an American evangelist, ordained Southern Baptist minister, and civil rights advocate, whose broadcasts and world tours featuring live sermons became well known in the mid- to late 20th century. Throughout his career, spanning over six decades, Graham rose to prominence as an evangelical Christian figure in the United States and abroad.
According to a biographer, Graham was considered "among the most influential Christian leaders" of the 20th century. Beginning in the late 1940s and early 1950s, Graham became known for filling stadiums and other massive venues around the world where he preached live sermons; these were often broadcast via radio and television with some continuing to be seen into the 21st century. During his six decades on television, Graham hosted his annual "crusades", evangelistic live-campaigns, from 1947 until his retirement in 2005. He also hosted the radio show Hour of Decision from 1950 to 1954. He openly repudiated racial segregation, at a time of intense racial strife in the United States, insisting on racial integration for all of his revivals and crusades, as early as 1953.
