Fuller held revival meetings down the West Coast of the United States, and soon began using radio as a method to get his message out. By 1930, he was regularly broadcasting Calvary's Sunday school services as well as Bible study programs in the local area. Eventually, the time he spent on the radio broadcast conflicted with the time he spent pastoring his church, so he either resigned his pastorship or was fired in 1933 and formed the nonprofit Gospel Broadcasting Association to support his radio efforts.
