Local R&B radio in the 1950s

Indie distribution is a car trunk; major distribution is a network. Before 1955 they can coexist. Local R&B radio is the pressure valve.

Stations court urban Black listeners with music plus ads for places that will actually serve them under Jim Crow—commercial, but also a map of safe commerce. Key outlets: WDIA Memphis (Rufus Thomas, B.B. King as DJs), WHBQ’s Dewey Phillips (early Elvis *That's All Right* airplay), WLAC Nashville, WGST Atlanta, KFVD Los Angeles (Hunter Hancock).

Alan Freed’s 1951 Cleveland show already sits in a national field of R&B DJs. Some Black listeners assumed the voice was Black—Freed was white—proof that the color line was leakier than the rhetoric. In New York on WINS the show morphs from Moon Dog to Rock and Roll Party (name fight with street performer Moon Dog); Freed claims the phrase. Whatever the etymology, the NYC platform scales it.

Portable and car radios let white teens eavesdrop without entering Black clubs or shops. When Freed packages “all-Black” package shows and finds white kids filling seats, the secret audience is visible. That teenage listenership is load-bearing for rock’s 1955 crossover.
