Since NBC was the broadcast arm of the Radio Corporation of America (RCA), its chief David Sarnoff approached his decisions as both a broadcaster and as a hardware executive; NBC's affiliates all had the latest RCA broadcasting equipment, and were often the best-established stations, or were on "clear channel" frequencies. Yet Sarnoff's affiliates were mistrustful of him. Paley had no such split loyalties: his and his affiliates' success rose and fell with the quality of CBS programming.[1]
