In 1932, a KFWB personality, Al Jarvis, began playing recorded music, a rarity on radio at the time, where music was usually performed live. He called his show "The World's Largest Make Believe Ballroom." In 1946, KFWB brought in two disc jockeys from New York City: Maurice Hart of WNEW, whose morning drive time show "Start the Day Right" was described as "Words and Music Straight from the Hart," and Martin Block, who shortened Jarvis' title to "The Make-Believe Ballroom." In those days, the DJs selected their own music, either from KFWB's extensive record library, or new songs brought to them by "song pluggers." Old and new, vocal and instrumental were mixed together to the disc jockey's choice.
