Category: Billboard 100
The Billboard Hot 100 is the music industry standard record chart in the United States for singles, published weekly by Billboard magazine. Chart rankings are based on radio play, online streaming, and sales (physical and digital).
The weekly sales period was originally Monday to Sunday when Nielsen started tracking sales in 1991, but since July 2015, this has been changed to Friday to Thursday. Radio airplay which, unlike sales figures and streaming data, is readily available on a real-time basis is tracked on a Monday to Sunday cycle (it was previously Wednesday to Tuesday). A new chart is compiled and officially released to the public by Billboard on Tuesdays.
