Billboard published a weekly chart in 1973 ranking the top-performing singles in the United States in soul music and related African American-oriented music genres; the chart has undergone various name changes over the decades to reflect the evolution of such genres and since 2005 has been published as Hot R&B/Hip-Hop Songs.
In the issue of Billboard dated January 6, Wonder's song "Superstition" reached number one, displacing the final chart-topper of 1972, "Me and Mrs. Jones" by Billy Paul.
The year's longest unbroken run at number one was achieved by Marvin Gaye, who spent six consecutive weeks atop the chart with "Let's Get It On".
Several acts gained the first number ones of their careers in 1973, beginning with Timmy Thomas,[4] who displaced Stevie Wonder from the top spot in late January with "Why Can't We Live Together".
In May and June, three consecutive chart-toppers were debut number ones for their respective artists, the Ohio Players, the Independents and Barry White.
