A new chart is compiled and officially released to the public by Billboard on Tuesdays.
The first number one song of the Hot 100 was "Poor Little Fool" by Ricky Nelson, on August 4, 1958.
On June 17, 1957, Billboard discontinued the Most Played in Jukeboxes chart, as the popularity of jukeboxes waned and radio stations incorporated more and more rock-oriented music into their playlists.
The week ending July 28, 1958 was the final publication of the Most Played By Jockeys and Top 100 charts, both of which had Perez Prado's instrumental version of "Patricia" ascending to the top.
Billboard has adjusted the sales/airplay ratio many times to more accurately reflect the true popularity of songs.
Billboard has also changed its Hot 100 policy regarding "two-sided singles" several times.
Radio airplay, which, unlike sales figures and streaming data, is readily available on a real-time basis, and is tracked on a Monday to Sunday cycle (previously Wednesday to Tuesday).
On August 4, 1958, Billboard premiered one main all-genre singles chart: the Hot 100.
The Hot 100 quickly became the industry standard and Billboard discontinued the Best Sellers In Stores chart on October 13, 1958.
At times, when singles sales were robust, more weight was given to a song's retail points than to its radio airplay.
As the decades passed, the recording industry concentrated more on album sales than singles sales.
The Billboard Hot 100 is the music industry standard record chart in the United States for singles, published weekly by Billboard magazine.
