History

The first chart published by ''Billboard'' was "Last Week's Ten Best Sellers Among The Popular Songs", a list of best-selling sheet music, in July 1913. Other early charts listed popular song performances in theatres and recitals in different cities. In 1928, "Popular Numbers Featured by Famous Singers and Leaders" appeared, which added radio performances to in-person performances. On January 4, 1936, ''Billboard'' magazine published its first pop chart based on record sales. Titled "Ten Best Records for Week Ending", it listed the 10 top-selling records of three leading record companies as reported by the companies themselves. In March 1937, the "Songs with the Most Radio Plugs" chart debuted with data from a separate company. In October 1938, a review list "The Week's Best Records" was retitled "The Billboard Record Buying Guide" by incorporating airplay and sheet music sales, which would eventually become the first trade survey of record popularity. In the July 27, 1940, issue, the first "Billboard Music Popularity Chart" was published for week ending July 20, with separate listings covering retail sales, sheet music sales,

The final accolade of a successful song was a position on the "Honor Roll of Hits", introduced in March 24, 1945, initially as a 10-song list, later expanded to 30 songs, which ranked the most popular songs by combining record and sheet sales, disk jockey, and jukebox performances as determined by ''Billboard's'' weekly nationwide survey. This chart amalgamated different records of the same song by different performers as one, and topping the first chart was "

(BDS), ''Billboard'' obtained its data from manual reports filled out by radio stations and stores. For different musical genres, which stations and stores are used separates the charts; each musical genre has a core audience or retail group. Each genre's department at ''Billboard'' is headed up by a chart manager, who makes these determinations. According to the 50th-anniversary issue of ''Billboard'', prior to the official implementation of SoundScan tracking in November 1991, many radio stations and retail stores removed songs from their manual reports after the associated record labels stopped promoting a particular single. Thus, songs fell quickly after peaking and had shorter chart lives. In 1990, the

singles chart was the first chart to use SoundScan and BDS. They were followed by the Hot 100 and the R&B chart in 1991. Today, all of the ''Billboard'' charts use this technology. Before September 1995, singles were allowed to chart in the week they first went on sale based on airplay points alone. The policy was changed in September 1995, to only allow a single to debut after a full week of sales on combined sales and airplay points. This allowed several tracks to debut at number one. In December 1998, the policy was further modified to allow tracks to chart on the basis of airplay alone without a commercial release. This change was made to reflect the changing realities of the music business. Previous to this, several substantial radio and MTV hits had not appeared on the ''Billboard'' chart at all, because many major labels chose not to release them as standalone singles, hoping their unavailability would spur greater

As a result of the changes, The ''Billboard'' 200, top albums sales, genre-based albums, digital songs, genre-based downloads, streaming songs, and genre-focused streaming surveys ran on a Friday-to-Thursday cycle. Radio Songs, which informs the Hot 100, synced to the Monday-to-Sunday period after formerly covering Wednesday to Tuesday. All other radio charts and genre tallies followed the Monday-to-Sunday cycle. The move was made to coincide with the IFPI's move to have all singles and albums released globally on Fridays."Billboard to Alter Chart Tracking Week for Global Release Date"

Incorporation of digital platforms

Starting on February 12, 2005, ''Billboard'' changed its methodology to include paid digital downloads from digital music retailers such as

. This change also allowed songs to chart with or without the help of radio airplay. This meant that a song did not need radio airplay to be eligible to chart on the ''Billboard'' Hot 100. With this policy change, a song could chart based on digital downloads alone. On July 31, 2007, ''Billboard'' changed its methodology for the Hot 100 chart to include digital streams. The digital information at the time was obtained from

and AOL's streaming platforms. This change was made exclusively to the ''Billboard'' Hot 100 chart. The effect of this chart change was minuscule at the time because it was estimated to account for 5% of the chart's total points. In October 2012, ''Billboard'' significantly changed the methodology for their country, rock, Latin, and rap charts, when it incorporated sales of digital downloads and streaming plays into what had been airplay-only charts. Another change was that rather than measuring airplay only from radio stations of the particular genre, the new methodology measures airplay from all radio formats. This methodology was extended to their Christian and gospel charts in late 2013. These methodology changes resulted in higher positions on the genre charts for songs with crossover appeal to other genres and radio formats (especially pop) at the expense of songs that appeal almost exclusively to core fans of the given genre, which was controversial with those devotees. On February 20, 2013, ''Billboard'' announced another change in the methodology for its charts that incorporated
