The campaign was scheduled for three weeks, but it was extended to eight weeks. During the campaign Graham spoke to 350,000 people, by the end, 3,000 of them decided to convert to Christianity. It was subsequently described as the greatest revival since the time of Billy Sunday. After this crusade Graham became a national figure in the United States.
