What has always been known in the U.S. as the Hot 100 had existed for nearly fifteen years as numerous charts, tracking and ranking the most popular singles of the day in several areas. During the 1940s and 1950s, popular singles were ranked on three significant charts:
• Best Sellers in Stores
• Most Played by Jockeys
• Most Played in Jukeboxes

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.
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.
The Billboard Hot 100 is still the standard by which a song's popularity is measured in the United States. The Hot 100 is ranked by radio airplay audience impressions as measured by Nielsen, sales data compiled by Nielsen (both at retail and digitally) and streaming activity provided by online music sources.
