Urban One was founded as Radio One in 1980 by Cathy Hughes, a then-recently divorced single mother, with the purchase of the Washington, D.C. radio station WOL-AM for $995,000. She changed the station's programming format from all-music to one that examined politics and culture from an African American perspective. Hughes purchased her second station, WMMJ in Washington, seven years later, which began to turn a profit once she converted it into a rhythm and blues station. This established Radio One's early strategy of purchasing small, underperforming radio stations in urban markets and refocusing them to serve the demographics of their communities.
