Billboard Hot 100

The Billboard Hot 100, also known as simply the Hot 100, is the music industry standard record chart in the United States for songs, published weekly by Billboard magazine. Chart rankings are based on sales (physical and digital), online streaming, and radio airplay in the U.S. A new chart is compiled and released online to the public by Billboard's website on Tuesdays but post-dated to the following Saturday, when the printed magazine first reaches newsstands. Since July 2015, the weekly tracking period for sales has been Friday–Thursday. It was initially Monday–Sunday when Nielsen started tracking sales in 1991.
