Hot Singles Sales: (per Billboard) 'the top selling singles compiled from a national sample of retail store, mass merchant and internet sales reports collected, compiled, and provided by Nielsen SoundScan.' The chart is released weekly and measures sales of physical commercial singles.Charts are ranked by number of gross audience impressions, computed by cross-referencing exact times of radio airplay with Arbitron listener data.' Hot 100 Airplay: (per Billboard) approximately 1,000 stations, 'composed of adult contemporary, R&B, hip hop, country, rock, gospel, Latin and Christian formats, digitally monitored twenty-four hours a day, seven days a week.There are several component charts that contribute to the overall calculation of the Hot 100. The Hot 100 is ranked by radio airplay audience impressions as measured by Nielsen BDS, sales data compiled by Nielsen Soundscan (both at retail and digitally) and streaming activity provided by online music sources. The Billboard Hot 100 is still the standard by which a song's popularity is measured in the United States. The Hot 100 quickly became the industry standard and Billboard discontinued the Best Sellers In Stores chart on October 13, 1958. On August 4, 1958, Billboard premiered one main all-genre singles chart: the Hot 100. The week ending Jwas 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. 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 Best Sellers in Stores, Most Played by Jockeys and Most Played in Jukeboxes charts continued to be published concurrently with the new Top 100 chart. The Top 100 combined all aspects of a single's performance (sales, airplay and jukebox activity), based on a point system that typically gave sales (purchases) more weight than radio airplay. On the week ending November 12, 1955, Billboard published The Top 100 for the first time. This was one of the main outlets of measuring song popularity with the younger generation of music listeners, as many radio stations resisted adding rock and roll music to their playlists for many years.ДЄlthough officially all three charts had equal 'weight' in terms of their importance, Billboard retrospectively considers the Best Sellers in Stores chart when referencing a song's performance before the creation of the Hot 100. Most Played in Jukeboxes ranked the most played songs in jukeboxes across the United States (20 positions).It ranked the most played songs on United States radio stations, as reported by radio DJs and radio stations (20 to 25 positions). Most Played by Jockeys was Billboard ' s original airplay chart.This chart ranked the biggest selling singles in retail stores, as reported by merchants surveyed throughout the country (20 to 50 positions). Best Sellers in Stores was the first Billboard chart, established in 1940.At the start of the rock era in 1955, there were three charts that measured songs by individual metrics: This chart ranked the most popular songs regardless of performer based on record and sheet sales, disk jockey, and jukebox performances as determined by Billboard 's weekly nationwide survey. Д«efore 1955, Billboard 's lead popularity chart was the Honor Roll of Hits, established in 1945. The chart's current number-one song is ' Easy on Me' by Adele. As of the issue for the week ending on January 15, 2022, the Billboard Hot 100 has had 1,132 different number one entries. The first number one song of the Billboard Hot 100 was ' Poor Little Fool' by Ricky Nelson, on August 4, 1958. A new chart is compiled and officially released to the public by Billboard on Tuesdays but post-dated to the following Saturday. Radio airplay, which, unlike sales figures and streaming, is readily available on a real-time basis, is also tracked on a Friday to Thursday cycle effective with the chart dated J (previously Monday to Sunday and before July 2015, Wednesday to Tuesday ). This tracking period also applies to compiling online streaming data. The weekly tracking period for sales was initially Monday to Sunday when Nielsen started tracking sales in 1991, but was changed to Friday to Thursday in July 2015. Chart rankings are based on sales (physical and digital), radio play, and online streaming in the United States. The Billboard Hot 100 is the music industry standard record chart in the United States for songs, published weekly by Billboard magazine.
